# AGENTS.md
|
||||
|
||||
This file guides code agents working in the LangBot main repository. `CLAUDE.md` is a symlink to this file.
|
||||
This file guides code agents (Claude Code, GitHub Copilot, OpenAI Codex, etc.) working in the LangBot project. `CLAUDE.md` is a symlink to this file.
|
||||
|
||||
Read `ARCHITECTURE.md` before non-trivial backend, frontend, runtime, plugin, Box, MCP, persistence, or cross-repo SDK changes. This file is the working checklist; `ARCHITECTURE.md` is the system map.
|
||||
## Project Overview
|
||||
|
||||
## Quick Facts
|
||||
LangBot is an open-source, LLM-native instant-messaging bot development platform. It aims to provide an out-of-the-box IM bot development experience with Agent, RAG, MCP and other LLM application capabilities, supporting mainstream global IM platforms and exposing rich APIs for custom development.
|
||||
|
||||
- Python backend: `>=3.11,<4.0`, dependencies managed by `uv`.
|
||||
- Frontend: `web/` is Vite + React Router 7 + shadcn/ui + Tailwind, managed by `pnpm`.
|
||||
- Backend framework: Quart served by Hypercorn on `api.port`, default `5300`.
|
||||
- Frontend dev server: `web/` on `3000`, with `VITE_API_BASE_URL` pointing at the backend.
|
||||
- Plugin/Box/runtime contracts live in sibling repo `langbot-plugin-sdk`, pinned as `langbot-plugin` in `pyproject.toml`.
|
||||
LangBot has a comprehensive web frontend — almost every operation can be performed through it.
|
||||
|
||||
## Essential Commands
|
||||
- **Python**: `>=3.11,<4.0`, dependencies managed by `uv`. Package version is in `pyproject.toml`.
|
||||
- **Frontend**: `web/` is a **Vite + React Router 7 + shadcn/ui + Tailwind CSS** SPA, managed by `pnpm`. (Note: this is NOT Next.js — the `dev` script is `vite`.)
|
||||
- **Backend framework**: Quart (the async flavour of Flask). The HTTP API and the pre-built web UI are both served by the backend on `http://127.0.0.1:5300`.

## Development Environment Setup
|
||||
|
||||
Full guide lives in the wiki: **["开发配置" / Dev Config](https://docs.langbot.app/zh/develop/dev-config)**. Summary:
|
||||
|
||||
### Backend
|
||||
|
||||
```bash
|
||||
uv sync --dev
|
||||
uv run main.py
|
||||
uv run pre-commit install
|
||||
pip install uv
|
||||
uv sync --dev # uv creates a .venv/ for you; point your editor's interpreter at it
|
||||
uv run main.py # serves API + web UI on http://127.0.0.1:5300
|
||||
```
|
||||
|
||||
On first run the config file is generated at `data/config.yaml`. DB is SQLite by default (zero setup); PostgreSQL is supported. Migrations run automatically on startup.
|
||||
|
||||
### Frontend
|
||||
|
||||
Requires Node.js + [pnpm](https://pnpm.io/installation).
|
||||
|
||||
```bash
|
||||
cd web
|
||||
cp .env.example .env # Windows: copy .env.example .env
|
||||
pnpm install
|
||||
pnpm dev
|
||||
pnpm build
|
||||
pnpm dev # http://127.0.0.1:3000 (npm install / npm run dev also work)
|
||||
```
|
||||
|
||||
Useful focused tests:
|
||||
`pnpm dev` reads `VITE_API_BASE_URL` from `web/.env` so the dev frontend can reach the backend on port `5300`. In production the frontend is pre-built into static files served by the backend on the same origin.
|
||||
|
||||
### Code formatting
|
||||
|
||||
The repo runs lint + format checks in CI. Install the pre-commit hooks so the same checks run locally before each commit:
|
||||
|
||||
```bash
|
||||
uv run pytest tests/unit_tests -q
|
||||
uv run pytest tests/integration -q
|
||||
uv run pytest tests/integration/persistence -q
|
||||
uv run pytest tests/manual/mcp_smoke.py
|
||||
|
||||
cd web
|
||||
pnpm lint
|
||||
pnpm test:e2e
|
||||
uv run pre-commit install
|
||||
```
|
||||
|
||||
Run the narrowest useful test first, then broader checks when confidence is needed.
|
||||
## Plugin System
|
||||
|
||||
## Where to Look
|
||||
LangBot's plugin system (Plugin SDK, CLI `lbp`, Plugin Runtime, and the shared entity/API definitions) lives in a **separate repository**: [`langbot-plugin-sdk`](https://github.com/langbot-app/langbot-plugin-sdk). LangBot depends on it via the pinned `langbot-plugin` package in `pyproject.toml`.
|
||||
|
||||
- Architecture map: `ARCHITECTURE.md`.
|
||||
- Dev environment guide: https://docs.langbot.app/zh/develop/dev-config.
|
||||
- Plugin runtime / CLI / SDK debugging: https://docs.langbot.app/zh/develop/plugin-runtime.
|
||||
- API-key auth: `docs/API_KEY_AUTH.md`.
|
||||
- Box deep-dive notes: `docs/review/box-architecture.md` and related files.
|
||||
- In-repo skills: `skills/` is the single source of truth for LangBot agent skills.
|
||||
- SDK repo: `../langbot-plugin-sdk/` when changing shared entities, plugin APIs, action protocol, `lbp rt`, or `lbp box`.
|
||||
### Architecture (what to know inside this repo)
|
||||
|
||||
## Cross-Repo SDK Work
|
||||
- Plugins run as independent processes managed by the **Plugin Runtime**. The Runtime supports two control transports: `stdio` and `websocket`.
|
||||
- When LangBot is started directly by a user (not in a container), it spawns and connects to the Runtime over **stdio** (lightweight/personal use).
|
||||
- When LangBot runs in a container, it connects to a standalone Runtime over **WebSocket** (production).
|
||||
- The bridge code lives in `src/langbot/pkg/plugin/` (`connector.py`, `handler.py`).
|
||||
- Relevant config (`data/config.yaml`): `plugin.runtime_ws_url` (e.g. `ws://langbot_plugin_runtime:5400/control/ws`). Start LangBot with `--standalone-runtime` to make it connect to an externally-launched Runtime over WebSocket instead of spawning one over stdio.
|
||||
|
||||
When changing SDK contracts used by LangBot:
|
||||
### Debugging the Plugin Runtime / CLI / SDK
|
||||
|
||||
This is documented in detail in the **SDK repo's `AGENTS.md`** and in the wiki page **["调试插件运行时、CLI、SDK" / Plugin Runtime](https://docs.langbot.app/zh/develop/plugin-runtime)**. The short version:
|
||||
|
||||
- Clone `LangBot` and `langbot-plugin-sdk` as siblings under one parent dir so the editor resolves shared entities.
|
||||
- Start a standalone Runtime from the SDK repo: `uv run --no-sync lbp rt` (control port `5400`, debug port `5401`).
|
||||
- To make LangBot use a locally-modified SDK: from the SDK dir, with LangBot's `.venv` active, run `uv pip install .`, then launch LangBot with `uv run --no-sync main.py --standalone-runtime` (keep `--no-sync` so your local SDK isn't overwritten).
|
||||
|
||||
### Debugging the Box (sandbox) runtime
|
||||
|
||||
The Box subsystem (`src/langbot/pkg/box/`) is the code sandbox. It picks the first available backend among **Docker / nsjail / E2B**. The standalone Box runtime is launched via the SDK CLI: `lbp box`. Backend selection details, the `lbp box` flags, and the SDK-side architecture are documented in the SDK repo's `AGENTS.md`.
|
||||
|
||||
Relevant config (`data/config.yaml`, `box:` section): `box.enabled` (master switch — disabling it also disables the native sandbox tools, skill add/edit, and stdio-mode MCP servers), `box.backend` (`'local'` = Docker/nsjail auto-pick, or `'docker'` / `'nsjail'` / `'e2b'`; also settable via `BOX__BACKEND`), and `box.runtime.endpoint` (external Box runtime base URL, e.g. `ws://127.0.0.1:5410`; empty = local auto-managed runtime). Like the plugin runtime, LangBot can connect to an externally-launched Box runtime by setting that endpoint and starting with `--standalone-box`.
|
||||
|
||||
> A common false "No supported sandbox backend (Docker / nsjail / E2B) is available" comes from Docker being installed and running but the current user not being in the `docker` group → `docker info` gets `permission denied` on the socket. Fix: `sudo usermod -aG docker <user>` and restart the backend in a shell that has the new group.
|
||||
|
||||
## Development Standards
|
||||
|
||||
- LangBot is a global project: **all code comments and docstrings must be in English**, and every user-facing string must support **i18n** (`en_US` + `zh_Hans` at minimum, plus `ja_JP` where the repo already has it).
|
||||
- LangBot is adopted in both toC and toB scenarios — always consider compatibility and security.
|
||||
- **Commit message format**: `<type>(<scope>): <subject>`
|
||||
- `type`: one of `feat`, `fix`, `docs`, `style`, `refactor`, `perf`, `test`, `chore`, etc.
|
||||
- `scope`: the affected package/module/file/class.
|
||||
- `subject`: concise description of the change.
|
||||
|
||||
### Database migrations (Alembic)
|
||||
|
||||
LangBot uses [Alembic](https://alembic.sqlalchemy.org/) for migrations, supporting both SQLite and PostgreSQL from a single set of scripts. Migration files live in `src/langbot/pkg/persistence/alembic/versions/`.
|
||||
|
||||
If you change ORM model definitions, generate a migration:
|
||||
|
||||
```bash
|
||||
# from langbot-plugin-sdk, with LangBot's .venv active
|
||||
uv pip install .
|
||||
|
||||
# from LangBot, preserve the locally installed SDK
|
||||
uv run --no-sync main.py
|
||||
# Run from the project root (requires data/config.yaml to exist)
|
||||
uv run python -m langbot.pkg.persistence.alembic_runner autogenerate "description of your change"
|
||||
```
|
||||
|
||||
For standalone runtime debugging:
|
||||
Review and edit the generated script before committing. Migrations execute automatically on startup. `autogenerate` detects schema changes (add/drop columns, tables, type changes) but **data migrations** (e.g. mutating JSON field contents) must be hand-written into the generated script. `env.py` sets `render_as_batch=True`, so SQLite's ALTER TABLE limits are handled automatically — no need to branch per database. More in the wiki ["开发配置"](https://docs.langbot.app/zh/develop/dev-config#数据库迁移).
|
||||
|
||||
```bash
|
||||
# in langbot-plugin-sdk
|
||||
uv run --no-sync lbp rt
|
||||
uv run --no-sync lbp box
|
||||
When writing a migration, follow these rules:
|
||||
|
||||
# in LangBot
|
||||
uv run --no-sync main.py --standalone-runtime
|
||||
uv run --no-sync main.py --standalone-box
|
||||
```
|
||||
- **Revision id ≤ 32 characters.** PostgreSQL stores `alembic_version.version_num` as `varchar(32)`; a longer id raises `StringDataRightTruncationError` at runtime. Prefer short, descriptive ids like `0005_add_llm_context_length`.
|
||||
- **Guard every operation against missing tables/columns.** Fresh installs build the schema via `create_all()` and then stamp the Alembic baseline, so a migration may run against a table that already has the change — or, in tests, against an empty database. Check `inspector.get_table_names()` / `inspector.get_columns(...)` before `add_column` / `drop_column`, mirroring the existing migrations.
|
||||
- **Keep a single linear head.** Chain `down_revision` to the current head; do not create branches. Run the migration tests after adding one: `uv run pytest tests/integration/persistence/ -q` (the PostgreSQL test needs a running PG via `TEST_POSTGRES_URL`).
|
||||
|
||||
Config keys to verify in `data/config.yaml` / `src/langbot/templates/config.yaml`:
|
||||
> **Legacy migration system (deprecated — do not extend).** The old 3.x migration system under `src/langbot/pkg/persistence/migrations/` (`DBMigration` subclasses in `dbmXXX_*.py`, run from `pkg/persistence/mgr.py`) is **frozen**. Do **not** add new `dbmXXX_*.py` files. The chain is capped at `required_database_version = 25` (`pkg/utils/constants.py`); those files only exist to upgrade pre-existing 3.x databases up to the Alembic baseline and are kept read-only. All new schema changes go through Alembic.
|
||||
|
||||
- Plugin runtime: `plugin.runtime_ws_url`, default Docker host `langbot_plugin_runtime:5400/control/ws`.
|
||||
- Box runtime: `box.enabled`, `box.backend`, `box.runtime.endpoint`, Docker host `langbot_box:5410`.
|
||||
- API/MCP auth: `api.global_api_key`.
|
||||
## Agent-Facing Surfaces (MCP + Skills)
|
||||
|
||||
## Change Rules
|
||||
LangBot is built to be **agent-friendly**. Three surfaces let AI agents work
|
||||
with LangBot, and they MUST be kept in lockstep with the HTTP API:
|
||||
|
||||
- HTTP API changes that should be agent-accessible must update the matching MCP tool in `src/langbot/pkg/api/mcp/server.py` and the relevant skill under `skills/` in the same pass.
|
||||
- New schema changes use Alembic under `src/langbot/pkg/persistence/alembic/versions/`; do not add legacy `dbmXXX` migrations.
|
||||
- New platform behavior belongs in platform adapters only for platform translation; pipeline/business logic belongs in `pkg/pipeline/` or services.
|
||||
- User-facing strings must support i18n (`en_US`, `zh_Hans`; include `ja_JP` where the repo already does).
|
||||
- Code comments and docstrings must be English.
|
||||
- Keep compatibility and security in mind; LangBot is used in both self-hosted/community and toB deployments.
|
||||
- Commit message format: `<type>(<scope>): <subject>`.
|
||||
1. **MCP server** — `src/langbot/pkg/api/mcp/` exposes a curated subset of the
|
||||
API as MCP tools at `/mcp` (API-key authenticated, including the
|
||||
`api.global_api_key` from config.yaml). `server.py` defines the tools (they
|
||||
call the service layer directly); `mount.py` is the ASGI dispatcher.
|
||||
2. **In-repo skills** — `skills/` is the **single source of truth** for agent
|
||||
skills (plugin/core/deploy/e2e/MCP-ops). Docs and the landing page link here
|
||||
rather than embedding their own copies.
|
||||
3. **API-key auth** — `api.global_api_key` (config.yaml) authenticates the API
|
||||
and MCP without a login session; see `docs/API_KEY_AUTH.md`.
|
||||
|
||||
## Runtime Pitfalls
|
||||
> **Maintenance rule (important).** When you add, remove, or change an HTTP API
|
||||
> endpoint that should be agent-accessible, you MUST update **both** the matching
|
||||
> MCP tool in `src/langbot/pkg/api/mcp/server.py` **and** the relevant skill under
|
||||
> `skills/` (especially `skills/skills/langbot-mcp-ops`). The API, the MCP tool
|
||||
> surface, and the skills are one system — drift between them is a bug.
|
||||
|
||||
- Local stdio Plugin Runtime disconnects do not auto-reconnect; restart LangBot if that path breaks.
|
||||
- Orphan runtime processes on `5400`/`5401` commonly break plugin debugging.
|
||||
- Use `uv run --no-sync` after locally installing the SDK, or `uv` may restore the pinned package.
|
||||
- A false Box “no backend” often means Docker is running but the current user lacks Docker socket permission.
|
||||
- Do not confuse external MCP servers LangBot connects to (`pkg/provider/tools/loaders/mcp.py`) with LangBot's own `/mcp` server (`pkg/api/mcp/`).
|
||||
- `CLAUDE.md` is a symlink to this file; edit `AGENTS.md`, not the symlink.

# Architecture
|
||||
|
||||
This document is a map of LangBot's moving parts. It is intentionally more stable than a feature guide and more concrete than the README: when you need to change behavior, start here, then follow the file references into the code.
|
||||
|
||||
For agent-specific working rules, see `AGENTS.md`. For plugin-runtime and Box-runtime implementation details, also read the sibling SDK repo: [`langbot-plugin-sdk`](https://github.com/langbot-app/langbot-plugin-sdk).
|
||||
|
||||
## What LangBot Is
|
||||
|
||||
LangBot is an open-source platform for building production IM bots backed by LLMs, agents, RAG, plugins, MCP tools, and a web management panel.
|
||||
|
||||
At runtime, one LangBot process owns:
|
||||
|
||||
- a Quart/Hypercorn HTTP service and the built web UI on `:5300`;
|
||||
- messaging-platform adapters such as Discord, Telegram, Slack, WeChat, QQ, WeCom, Lark, DingTalk, KOOK, LINE, Satori, Matrix, and HTTP/WebSocket bots;
|
||||
- a pipeline engine that turns inbound platform messages into LLM/tool/plugin work and replies;
|
||||
- persistence, storage, vector database, telemetry, monitoring, and configuration managers;
|
||||
- bridges to the Plugin Runtime and Box Runtime provided by `langbot-plugin-sdk`;
|
||||
- an MCP server at `/mcp` exposing a curated agent-facing subset of the service layer.
|
||||
|
||||
## Repository Boundary
|
||||
|
||||
LangBot is not a single-repo system.
|
||||
|
||||
- `LangBot/` is the main product: backend, web UI, platform adapters, pipeline engine, HTTP API, MCP server, RAG, persistence, skills integration, and the bridge code that talks to runtimes.
|
||||
- `langbot-plugin-sdk/` is published as `langbot-plugin` and pinned in `LangBot/pyproject.toml`. It contains plugin developer APIs, shared entities, `lbp`, the Plugin Runtime (`lbp rt`), and the Box Runtime (`lbp box`).
|
||||
- Plugins import SDK APIs from `langbot_plugin.*`; the LangBot main process imports the same package for shared entities and runtime protocols.
|
||||
|
||||
This split matters. If a change modifies SDK entities, component APIs, action protocols, `lbp rt`, or `lbp box`, verify the sibling SDK repo and install the local SDK into LangBot's virtualenv when testing cross-repo behavior.
|
||||
|
||||
## Startup Path
|
||||
|
||||
The process entrypoint is small and layered:
|
||||
|
||||
1. `main.py` delegates to `langbot.__main__.main()`.
|
||||
2. `src/langbot/__main__.py` parses `--standalone-runtime`, `--standalone-box`, and `--debug`, checks dependencies, generates missing config/data files, and calls `pkg.core.boot.main()`.
|
||||
3. `pkg/core/boot.py` executes startup stages in order: `LoadConfigStage`, `GenKeysStage`, `SetupLoggerStage`, `BuildAppStage`, `ShowNotesStage`.
|
||||
4. `BuildAppStage` constructs the `Application` object by wiring managers, services, runtime connectors, and controllers.
|
||||
5. `Application.run()` starts the platform manager, query controller, HTTP controller, telemetry/cleanup loops, and plugin initialization.
|
||||
|
||||
The central runtime object is `pkg/core/app.py::Application`. It is a service locator for long-lived managers. That is not elegant, but it is the current architectural center; most subsystems receive `ap: Application` and collaborate through it.

## The Runtime Graph
|
||||
|
||||
The most useful mental model is this graph:
|
||||
|
||||
```text
|
||||
Platform adapter
|
||||
→ RuntimeBot
|
||||
→ MessageAggregator
|
||||
→ QueryPool
|
||||
→ Controller
|
||||
→ RuntimePipeline
|
||||
→ PipelineStage chain
|
||||
→ RequestRunner / ToolManager / PluginRuntimeConnector / BoxService
|
||||
→ response via adapter
|
||||
```
|
||||
|
||||
The HTTP and MCP surfaces are parallel entrypoints into the same service layer:
|
||||
|
||||
```text
|
||||
HTTP client / Web UI
|
||||
→ Quart route group
|
||||
→ api/http/service/*
|
||||
→ Application managers / persistence / runtime connectors
|
||||
|
||||
MCP client
|
||||
→ /mcp mount
|
||||
→ api/mcp/server.py tools
|
||||
→ the same service layer directly
|
||||
```
|
||||
|
||||
## Message Flow
|
||||
|
||||
Inbound platform messages enter through adapter-specific SDK callbacks. The common path is:
|
||||
|
||||
1. A platform adapter under `pkg/platform/sources/` converts platform-specific events into SDK message/event entities.
|
||||
2. `RuntimeBot` in `pkg/platform/botmgr.py` applies pipeline routing rules and either discards the message, pushes it to webhooks, or sends it to the message aggregator.
|
||||
3. `MessageAggregator` batches/normalizes messages before adding a `Query` to `QueryPool`.
|
||||
4. `Controller` in `pkg/pipeline/controller.py` selects queries subject to global pipeline concurrency and per-session concurrency.
|
||||
5. `RuntimePipeline` in `pkg/pipeline/pipelinemgr.py` runs configured pipeline stages using a responsibility-chain style executor that supports generator stages.
|
||||
6. The chat stage emits plugin events, calls a configured `RequestRunner`, handles streaming/non-streaming responses, records telemetry, and appends conversation history.
|
||||
7. Output stages send text, cards, chunks, files, or error notices back through the original platform adapter.
|
||||
|
||||
Pipeline components are registered by decorators and package import side effects. When adding a new stage, loader, runner, or adapter, check the corresponding preregistration mechanism instead of inventing a second registry.
|
||||
|
||||
## Platform Layer
|
||||
|
||||
Platform code lives under `pkg/platform/`.
|
||||
|
||||
- `botmgr.py` owns runtime bots, routing rules, event logging, webhook pushing, and adapter lifecycle.
|
||||
- `sources/` contains adapter implementations. Each adapter subclasses `langbot_plugin.api.definition.abstract.platform.adapter.AbstractMessagePlatformAdapter` from the SDK.
|
||||
- Platform entities such as `MessageChain`, `Image`, `At`, `Voice`, and events come from `langbot-plugin-sdk`, not from this repo.
|
||||
|
||||
The platform layer should translate between external platform APIs and LangBot's shared message/event model. It should not contain LLM-provider logic or pipeline business logic.
|
||||
|
||||
## Pipeline Layer
|
||||
|
||||
Pipeline code lives under `pkg/pipeline/`.
|
||||
|
||||
Important pieces:
|
||||
|
||||
- `pool.py::QueryPool` stores pending queries and cached in-flight queries for plugin backward-compatible calls.
|
||||
- `controller.py::Controller` schedules query processing and enforces concurrency.
|
||||
- `pipelinemgr.py::RuntimePipeline` materializes database pipeline config into a runtime stage chain.
|
||||
- `process/handlers/chat.py::ChatMessageHandler` is the main LLM conversation handler.
|
||||
- Stage families include response rules, banned sessions, content filters, preprocessors, rate limits, message truncation, long text handling, response-back, command handling, and wrappers.
|
||||
|
||||
Pipelines are configuration-driven. Prefer adding a stage or extending an existing stage family over hard-coding behavior in platform adapters.
|
||||
|
||||
## Provider, RAG, and Tools
|
||||
|
||||
Provider code lives under `pkg/provider/`.
|
||||
|
||||
- `modelmgr/` manages configured model providers and requesters.
|
||||
- `runners/` implements request runners such as the local agent runner and external workflow integrations.
|
||||
- `tools/toolmgr.py` aggregates tools from native tools, plugin tools, external MCP servers, and skill-authoring tools.
|
||||
- `tools/loaders/mcp.py` is the MCP client side: external MCP servers that LangBot connects to for agent tools.
|
||||
- RAG lives across `pkg/rag/`, `pkg/vector/`, model services, and plugin KnowledgeEngine actions.
|
||||
|
||||
Do not confuse LangBot's MCP client side with LangBot's own MCP server at `/mcp`; they are different surfaces.
|
||||
|
||||
## Plugin System
|
||||
|
||||
The plugin system crosses the repo boundary.
|
||||
|
||||
In this repo:
|
||||
|
||||
- `pkg/plugin/connector.py` connects LangBot to the Plugin Runtime over stdio or WebSocket.
|
||||
- `pkg/plugin/handler.py` exposes LangBot actions to the runtime and calls runtime actions for plugin operations.
|
||||
- `pkg/provider/tools/loaders/plugin.py` exposes plugin Tool components to LLM runners.
|
||||
- Pipeline handlers emit SDK events such as normal-message events and prompt-processing events.
|
||||
|
||||
In `langbot-plugin-sdk`:
|
||||
|
||||
- `src/langbot_plugin/api/` defines `BasePlugin`, component base classes, message/event entities, contexts, proxies, and manifests.
|
||||
- `src/langbot_plugin/runtime/` implements `lbp rt`, plugin discovery, dependency installation, process launching, and control/debug connections.
|
||||
- `src/langbot_plugin/entities/io/` defines the action protocol shared by LangBot, runtime, and plugin processes.
|
||||
|
||||
The Plugin Runtime supports stdio and WebSocket control transports. Direct local LangBot runs usually spawn the runtime over stdio. Containerized/standalone deployments connect over WebSocket using `plugin.runtime_ws_url` and `--standalone-runtime`.
|
||||
|
||||
## Box Runtime and Skills
|
||||
|
||||
Box is the sandbox subsystem used by native agent tools, stdio MCP servers, skill authoring, and managed processes.
|
||||
|
||||
In this repo:
|
||||
|
||||
- `pkg/box/service.py` is the application-facing facade for exec, sessions, managed processes, skill CRUD, status, reconnects, quotas, mounts, and sandbox profiles.
|
||||
- `pkg/box/connector.py` connects to the Box Runtime over stdio, Windows subprocess+WebSocket, or remote WebSocket.
|
||||
- `pkg/provider/tools/loaders/native.py`, `mcp_stdio.py`, and skill loaders depend on Box availability.
|
||||
- `pkg/skill/manager.py` loads skills from the Box runtime, falling back to local `data/skills` when needed.
|
||||
|
||||
In `langbot-plugin-sdk`:
|
||||
|
||||
- `src/langbot_plugin/box/server.py` implements `lbp box` and the WebSocket endpoints on `:5410`.
|
||||
- `src/langbot_plugin/box/runtime.py` owns sandbox sessions and managed processes.
|
||||
- `backend.py`, `nsjail_backend.py`, and `e2b_backend.py` implement sandbox backends.
|
||||
- `skill_store.py` manages skill packages from the Box side.
|
||||
|
||||
Important config keys live under `box:` in `src/langbot/templates/config.yaml`: `box.enabled`, `box.backend`, `box.runtime.endpoint`, and `box.local.*`. Start LangBot with `--standalone-box` when connecting to an externally launched Box runtime.
|
||||
|
||||
## HTTP API, Web UI, and MCP Server
|
||||
|
||||
`pkg/api/http/controller/main.py` builds a Quart app, registers route groups, serves the built SPA, and wraps the ASGI app with the MCP dispatcher.
|
||||
|
||||
- HTTP route groups live under `pkg/api/http/controller/groups/`.
|
||||
- Service-layer logic lives under `pkg/api/http/service/`.
|
||||
- The built web UI is served from the frontend build path with SPA fallback.
|
||||
- The MCP server lives under `pkg/api/mcp/` and is mounted at `/mcp`.
|
||||
|
||||
The MCP server intentionally exposes a curated subset of the API. Tools call service classes directly rather than making HTTP requests back into LangBot.
|
||||
|
||||
Maintenance rule: when adding, removing, or changing an HTTP endpoint that should be agent-accessible, update the matching MCP tool and the relevant in-repo skill under `skills/` in the same pass.
|
||||
|
||||
## Persistence and Configuration
|
||||
|
||||
Persistence is centered on `pkg/persistence/mgr.py`.
|
||||
|
||||
- SQLite is the default database; PostgreSQL is supported.
|
||||
- Models live under `pkg/entity/persistence/`.
|
||||
- Fresh schemas are created from metadata, then legacy migrations run up to the frozen 3.x baseline, then Alembic migrations run to head.
|
||||
- New schema changes should use Alembic under `pkg/persistence/alembic/versions/`; do not extend the frozen legacy migration chain.
|
||||
|
||||
Configuration starts from `src/langbot/templates/config.yaml` and is generated into `data/config.yaml` on first run. Most long-lived managers read from `ap.instance_config.data`.
|
||||
|
||||
## Frontend
|
||||
|
||||
The frontend lives in `web/` and is a Vite SPA using React Router 7, shadcn/ui, Tailwind CSS, and pnpm. It is not Next.js, despite some historical filenames.
|
||||
|
||||
In development, `pnpm dev` serves the UI on `:3000` and reads `VITE_API_BASE_URL` to call the backend on `:5300`. In production, the built frontend is packaged into the Python distribution and served by the backend.
|
||||
|
||||
Keep frontend API behavior aligned with `pkg/api/http/service/` and route groups. User-facing strings must go through the existing i18n setup.
|
||||
|
||||
## Agent-Facing Surfaces
|
||||
|
||||
LangBot is deliberately agent-friendly. The agent-facing surfaces are part of the architecture, not extra docs.
|
||||
|
||||
- `skills/` is the single source of truth for in-repo skills.
|
||||
- `pkg/api/mcp/server.py` exposes the LangBot MCP server at `/mcp`.
|
||||
- `api.global_api_key` authenticates API/MCP access without a browser login.
|
||||
- `AGENTS.md` and `ARCHITECTURE.md` tell coding agents how the repo works.
|
||||
|
||||
When one of these changes, update the others if the behavior or contract changed. API, MCP tools, and skills are one system; drift is a bug.
|
||||
|
||||
## Where to Change Things
|
||||
|
||||
- New HTTP API: add/adjust a service in `pkg/api/http/service/`, a route group in `pkg/api/http/controller/groups/`, tests, and MCP/skills if agent-accessible.
|
||||
- New platform adapter: add a `pkg/platform/sources/*` adapter, component metadata/templates as needed, i18n, docs, and tests/smoke coverage.
|
||||
- New pipeline behavior: add or extend a pipeline stage family under `pkg/pipeline/`; avoid putting pipeline rules in adapters.
|
||||
- New LLM provider/requester: work under `pkg/provider/modelmgr/` and related service/UI surfaces.
|
||||
- New LLM tool source: extend `pkg/provider/tools/loaders/` and `ToolManager` intentionally.
|
||||
- New plugin component/API/protocol: change `langbot-plugin-sdk` first or in lockstep, then update LangBot bridge code.
|
||||
- New Box capability: change both `pkg/box/` and `langbot-plugin-sdk/src/langbot_plugin/box/`, plus config and tests.
|
||||
- New database schema: add an Alembic migration, not a legacy `dbmXXX` migration.
|
||||
|
||||
## Design Biases
|
||||
|
||||
- Keep platform translation, pipeline orchestration, provider execution, and runtime protocols separate.
|
||||
- Reuse existing registries and service layers instead of adding parallel paths.
|
||||
- Prefer small, explicit agent surfaces over exposing every internal API.
|
||||
- Treat cross-repo contracts with the SDK as public interfaces.
|
||||
- Test behavior at the narrowest useful layer first, then add integration/e2e coverage for runtime or platform changes.

# HTTP Bot Adapter — Design Document
|
||||
|
||||
> Status: **Implemented** · Branch: `feat/http-bot-adapter` · Author: LangBot core
|
||||
>
|
||||
> A first-class, **standalone** message-platform adapter (`http_bot`) that lets
|
||||
> any external system (e.g. LangBot Space ticketing, an internal back-office, a
|
||||
> CRM, a custom web app) talk to a LangBot pipeline over plain HTTP — **inbound**
|
||||
> by POSTing messages in, **outbound** by receiving replies on a callback URL —
|
||||
> with full support for the pipeline's native N→1 aggregation and 1→M
|
||||
> multi-reply semantics, and **without** holding a long-lived WebSocket
|
||||
> connection.
|
||||
>
|
||||
> **Shipped in this branch:**
|
||||
> - `src/langbot/pkg/platform/sources/http_bot.yaml` — adapter manifest (auto-discovered)
|
||||
> - `src/langbot/pkg/platform/sources/http_bot.py` — `HttpBotAdapter`
|
||||
> - `src/langbot/pkg/platform/sources/http_bot_signing.py` — HMAC helpers
|
||||
> - `src/langbot/pkg/platform/sources/http_bot.svg` — icon
|
||||
> - `docs/platforms/http-bot.md` — integration guide
|
||||
> - `docs/http-bot-openapi.json` — machine-readable contract
|
||||
> - `examples/http-bot/` — Python + TypeScript reference clients
|
||||
>
|
||||
> **Final decisions (resolving the original open questions):**
|
||||
> 1. Callback URL is **config-only** — never accepted per-message (SSRF closed).
|
||||
> 2. **Session reset is provided** — `POST /bots/<uuid>/reset` keyed by `session_id`.
|
||||
> 3. Reference **clients are provided** — `examples/http-bot/client.py` + `client.ts`.
|
||||
> 4. **Sync convenience mode is included** — `POST /bots/<uuid>/sync` (opt-in, lossy).

|
||||
|
||||
## 1. Background & Motivation
|
||||
|
||||
### 1.1 The concrete need
|
||||
|
||||
LangBot Space wants to use a LangBot pipeline as the brain for **ticket
|
||||
handling**. The integration is **server-to-server**: Space's backend pushes a
|
||||
user's ticket messages into LangBot and renders LangBot's replies back into the
|
||||
ticket thread.
|
||||
|
||||
This interaction is **not** request/response shaped:
|
||||
|
||||
- **N → 1**: a user may fire several messages in a row ("the app crashed" …
|
||||
"when I click export" … "here's a screenshot"). The pipeline's
|
||||
**message aggregation** feature should debounce and merge these into one turn.
|
||||
- **1 → N**: a single turn may yield **multiple** outbound messages — a tool/
|
||||
function call narrating progress, a plugin emitting several cards, a streamed
|
||||
answer split into chunks.
|
||||
|
||||
### 1.2 Why the existing options don't fit
|
||||
|
||||
LangBot today exposes exactly one externally-reachable way to drive a pipeline
|
||||
that is **not** tied to a specific IM vendor: the **WebSocket** path
|
||||
(`/api/v1/pipelines/<uuid>/ws/connect` for dashboard debug, and
|
||||
`/api/v1/embed/<bot_uuid>/ws/connect` for the embeddable web widget).
|
||||
|
||||
For a server-to-server integration the WebSocket path has real friction:
|
||||
|
||||
| Problem | Detail |
|
||||
|---|---|
|
||||
| Long-lived connection | Caller must maintain a socket, heartbeats, and reconnect logic for what is fundamentally a fire-and-collect workload. |
|
||||
| Session identity | Inbound messages are keyed by the transient `connection_id` (`websocket_{connection_id}`); the caller **cannot supply a stable, business-meaningful session id** (e.g. a ticket number). Multi-ticket isolation is not expressible. |
|
||||
| Auth mismatch | The debug socket is gated by the **dashboard JWT** (must not be handed to an external service); the embed socket is gated by **Cloudflare Turnstile** (a *browser* human-check that a backend cannot satisfy). Neither is a server-to-server credential. |
|
||||
| In-memory, single-process state | Session history lives in process memory and is lost on restart. |
|
||||
|
||||
> **Key realisation.** The N→1 / 1→M behaviour the caller wants is **not**
|
||||
> provided by WebSocket — it is provided by the **pipeline** (aggregation +
|
||||
> the adapter being free to call `reply_message` any number of times). It is
|
||||
> therefore **transport-independent**. We can deliver the exact same semantics
|
||||
> over a far lighter HTTP transport.
|
||||
|
||||
### 1.3 Why a *new, standalone* adapter (not a refactor of an existing one)
|
||||
|
||||
The brief is explicit: **do not reuse / fork an existing vendor adapter.** The
|
||||
vendor adapters (`lark`, `wecom`, `qqofficial`, `slack`, …) carry vendor-specific
|
||||
signature schemes, payload shapes, and message-segment mappings. Bending one of
|
||||
them into a "generic" mode would couple a public integration surface to one
|
||||
vendor's quirks and make the developer experience worse for everyone.
|
||||
|
||||
Instead we ship `http_bot` as a clean, independent adapter whose **entire
|
||||
contract is LangBot's own** — documented, versioned, and designed front-to-back
|
||||
around *integrator* developer experience.
|
||||
|
||||
---
|
||||
|
||||
## 2. Goals & Non-Goals
|
||||
|
||||
### Goals
|
||||
|
||||
- **G1** A standalone `http_bot` adapter, selectable like any other platform
|
||||
adapter in the dashboard, with its own config schema and docs.
|
||||
- **G2** **Inbound**: external systems POST messages to a stable LangBot URL,
|
||||
carrying a **caller-defined `session_id`** that maps 1:1 to a LangBot session.
|
||||
- **G3** **Outbound**: LangBot delivers each reply by POSTing to a
|
||||
caller-configured **callback URL**; one turn may produce **many** callbacks.
|
||||
- **G4** Preserve pipeline-native **N→1 aggregation** and **1→M multi-reply**.
|
||||
- **G5** Server-to-server **auth**: shared-secret HMAC request signing both
|
||||
directions (no JWT, no Turnstile, no long-lived socket).
|
||||
- **G6** **Great DX**: copy-pasteable curl, a tiny reference client, an OpenAPI
|
||||
fragment, idempotency, clear error envelope, and a local echo-server recipe.
|
||||
|
||||
### Non-Goals
|
||||
|
||||
- Not replacing or deprecating the WebSocket / embed widget path (that remains
|
||||
the right tool for *browser*, real-time, streaming chat UIs).
|
||||
- Not a synchronous "one request → one response" RPC (explicitly rejected: it
|
||||
cannot express 1→M; see §9 for the optional sync convenience mode).
|
||||
- No built-in message **persistence/replay** in v1 (callbacks are at-least-once
|
||||
best-effort; durability is the caller's responsibility — see §8).
|
||||
- No multi-tenant API-key management UI in v1 (one secret per bot; see §11).
|
||||
|
||||
---
|
||||
|
||||
## 3. How LangBot routes a message (the parts we plug into)
|
||||
|
||||
Understanding the existing flow is what makes this adapter cheap. A message
|
||||
flows through these stages (verified against current `master`):
|
||||
|
||||
```
|
||||
INBOUND OUTBOUND
|
||||
external POST ─┐ ┌─ reply_message()
|
||||
▼ │ reply_message_chunk()
|
||||
POST /bots/<bot_uuid> (unified webhook router, AuthType.NONE)
|
||||
│ webhooks.py → adapter.handle_unified_webhook(bot_uuid, path, request)
|
||||
▼ │
|
||||
HttpBotAdapter.handle_unified_webhook │ (called 0..N times
|
||||
• verify HMAC signature │ per turn by the
|
||||
• parse {session_id, message[]} │ pipeline / plugins)
|
||||
• build FriendMessage / GroupMessage │
|
||||
• fire registered listener ───────────────┐ │
|
||||
│ │ │
|
||||
▼ ▼ │
|
||||
botmgr.on_friend_message / on_group_message │
|
||||
• (optional) webhook_pusher fan-out │
|
||||
• msg_aggregator.add_message(...) ── N→1 debounce ──►│
|
||||
│ │
|
||||
▼ │
|
||||
query_pool → pipeline.run() ─── invokes adapter ─────┘
|
||||
reply methods 1..M times
|
||||
```
|
||||
|
||||
Two framework facts we rely on:
|
||||
|
||||
1. **N→1 aggregation is free.** `botmgr` hands every inbound event to
|
||||
`self.ap.msg_aggregator.add_message(...)`, which debounces per
|
||||
`session_id` and merges consecutive messages into one pipeline turn
|
||||
(`pkg/pipeline/aggregator.py`). The adapter does nothing special.
|
||||
|
||||
2. **1→M is free.** The pipeline (and any plugin in the chain) calls
|
||||
`adapter.reply_message()` / `reply_message_chunk()` **as many times as it
|
||||
wants** per turn. The adapter's only job is to deliver each call outward.
|
||||
For `http_bot` that means: **one outbound callback POST per call.**
|
||||
|
||||
3. **A unified inbound route already exists.** `WebhookRouterGroup`
|
||||
(`pkg/api/http/controller/groups/webhooks.py`) maps
|
||||
`POST /bots/<bot_uuid>[/<path>]` (auth `NONE`) to
|
||||
`adapter.handle_unified_webhook(bot_uuid, path, request)`. `http_bot`
|
||||
implements that method and is reachable **without registering any new
|
||||
route** — it does its own signature verification, exactly like the vendor
|
||||
webhook adapters do.
|
||||
|
||||
> Net new code is essentially: one `http_bot.py` adapter, one `http_bot.yaml`
|
||||
> schema, signing helpers, and docs. No router, aggregator, or pipeline changes.
|
||||
|
||||

|
||||
|
||||
## 4. Architecture Overview
|
||||
|
||||
```
|
||||
┌────────────────────┐ (1) inbound: POST signed message
|
||||
│ External system │ ──────────────────────────────────────────────► ┌──────────────────────┐
|
||||
│ (LangBot Space, │ POST /bots/<bot_uuid> │ LangBot │
|
||||
│ CRM, web app …) │ X-LB-Signature, X-LB-Timestamp │ │
|
||||
│ │ { session_id, message:[...] } │ HttpBotAdapter │
|
||||
│ - callback server │ ◄────────────────────────────────────────────── │ (platform/sources) │
|
||||
│ (receives │ (4) outbound: POST signed reply(s) │ │
|
||||
│ replies) │ POST <callback_url> │ pipeline + aggregator│
|
||||
└────────────────────┘ X-LB-Signature, X-LB-Timestamp └──────────────────────┘
|
||||
{ session_id, sequence, is_final,
|
||||
message:[...] } (sent 1..M times)
|
||||
```
|
||||
|
||||
- The adapter is **stateless across requests** at the HTTP layer; session
|
||||
continuity is carried by `session_id` and resolved by LangBot's normal
|
||||
session manager.
|
||||
- **Inbound** and **outbound** are **independent HTTP exchanges**. LangBot does
|
||||
not answer the inbound POST with the pipeline result; it `202 Accepts` it and
|
||||
later POSTs the reply(s) to the callback URL. This is what makes 1→M natural.
|
||||
|
||||
---
|
||||
|
||||
## 5. Configuration Schema (`http_bot.yaml`)
|
||||
|
||||
Follows the existing `MessagePlatformAdapter` manifest convention (cf.
|
||||
`slack.yaml`). Fields:
|
||||
|
||||
| field | type | required | purpose |
|
||||
|---|---|---|---|
|
||||
| `inbound_secret` | string (secret) | yes | HMAC key the **caller** uses to sign inbound POSTs; LangBot verifies. |
|
||||
| `callback_url` | string (url) | no* | Where LangBot POSTs replies. *Optional if the caller supplies `callback_url` per-message (see §6.1); a static default lives here. |
|
||||
| `outbound_secret` | string (secret) | no | HMAC key LangBot uses to sign outbound callbacks; caller verifies. Defaults to `inbound_secret` if empty. |
|
||||
| `default_session_type` | enum `person`/`group` | no | Default when a message omits `session_type`. Default `person`. |
|
||||
| `signature_required` | bool | no | If `false`, skip inbound signature check (dev only; logs a warning). Default `true`. |
|
||||
| `callback_timeout` | int (seconds) | no | Per-callback HTTP timeout. Default `15`. |
|
||||
| `callback_max_retries` | int | no | Retries on 5xx/timeout with backoff. Default `3`. |
|
||||
| `webhook_url` | webhook-url (display) | — | Read-only field rendering the inbound URL `…/bots/<bot_uuid>` for copy-paste, like other webhook adapters. |
|
||||

||||

|
||||
## 6. The HTTP Contract (this is the DX surface)
|
||||
|
||||
### 6.1 Inbound — push a message into LangBot
|
||||
|
||||
```
|
||||
POST /bots/{bot_uuid}
|
||||
Content-Type: application/json
|
||||
X-LB-Timestamp: 1718000000
|
||||
X-LB-Signature: sha256=<hex hmac>
|
||||
X-LB-Idempotency-Key: <uuid> # optional, dedup window
|
||||
```
|
||||
|
||||
Body:
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"session_id": "ticket-10293", // REQUIRED. Caller-defined. Maps 1:1 to a LangBot session.
|
||||
"session_type": "person", // optional, "person" | "group"; default from config
|
||||
"sender": { // optional metadata, surfaced to pipeline/plugins
|
||||
"id": "user-5567",
|
||||
"name": "Alice"
|
||||
},
|
||||
"message": [ // REQUIRED. A LangBot MessageChain (list of segments).
|
||||
{ "type": "Plain", "text": "Export keeps failing on the dashboard." },
|
||||
{ "type": "Image", "url": "https://.../screenshot.png" }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
Response (LangBot does **not** block on the pipeline):
|
||||
|
||||
```jsonc
|
||||
// 202 Accepted
|
||||
{
|
||||
"code": 0,
|
||||
"msg": "accepted",
|
||||
"data": {
|
||||
"session_id": "ticket-10293",
|
||||
"accepted_message_id": "in_01H....", // server-assigned id for this inbound message
|
||||
"aggregating": true // true if buffered by the aggregator
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**N→1 in practice.** Fire three POSTs with the same `session_id` inside the
|
||||
aggregation window → the pipeline runs **once** with the three messages merged.
|
||||
No special flag needed; this is the aggregator's default behaviour when enabled
|
||||
on the pipeline.
|
||||
|
||||
### 6.2 Outbound — LangBot delivers replies to your callback
|
||||
|
||||
For each `reply_message` / `reply_message_chunk` the pipeline emits, LangBot
|
||||
POSTs to `callback_url`:
|
||||
|
||||
```
|
||||
POST {callback_url}
|
||||
Content-Type: application/json
|
||||
X-LB-Timestamp: 1718000001
|
||||
X-LB-Signature: sha256=<hex hmac over body>
|
||||
```
|
||||
|
||||
Body:
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"session_id": "ticket-10293", // echoes the inbound session
|
||||
"reply_to": "in_01H....", // the inbound message id this answers
|
||||
"sequence": 1, // 1-based ordinal within this turn (for 1→M ordering)
|
||||
"is_final": false, // false for intermediate/streamed parts
|
||||
"stream": false, // true when this is a streamed chunk
|
||||
"message": [
|
||||
{ "type": "Plain", "text": "Looking into it — checking your export logs…" }
|
||||
],
|
||||
"timestamp": "2026-06-22T09:00:01Z"
|
||||
}
|
||||
```
|
||||
|
||||
**1→M in practice.** A turn that fires a function call then a final answer
|
||||
produces e.g.:
|
||||
|
||||
```
|
||||
POST callback → { sequence: 1, is_final: false, message: ["Checking logs…"] }
|
||||
POST callback → { sequence: 2, is_final: false, message: ["Found 2 failed exports."] }
|
||||
POST callback → { sequence: 3, is_final: true, message: ["Fixed. Try again now."] }
|
||||
```
|
||||
|
||||
The caller stitches by `session_id` + `sequence`, and knows the turn is complete
|
||||
when `is_final: true` arrives.
|
||||
|
||||
Your callback endpoint should return `200` quickly. A non-2xx triggers retry
|
||||
with backoff (`callback_max_retries`).
|
||||
|
||||
### 6.3 Error envelope (inbound)
|
||||
|
||||
Consistent, machine-readable; never leak internals:
|
||||
|
||||
```jsonc
|
||||
{ "code": 40101, "msg": "invalid signature", "data": null }
|
||||
```
|
||||
|
||||
| HTTP | code | meaning |
|
||||
|---|---|---|
|
||||
| 202 | 0 | accepted |
|
||||
| 400 | 40001 | malformed body / missing `session_id` or `message` |
|
||||
| 401 | 40101 | bad/expired signature |
|
||||
| 403 | 40301 | bot disabled |
|
||||
| 404 | 40401 | bot_uuid not found / not an `http_bot` adapter |
|
||||
| 409 | 40901 | duplicate idempotency key (already accepted) |
|
||||
| 413 | 41301 | message too large |
|
||||
| 500 | 50001 | internal error |
|
||||
|
||||
---
|
||||
|
||||
## 7. Signing scheme (both directions)
|
||||
|
||||
Symmetric, dependency-free HMAC-SHA256 — trivial to implement in any language.
|
||||
|
||||
```
|
||||
signing_string = "{timestamp}.{raw_request_body}"
|
||||
signature = "sha256=" + hex(HMAC_SHA256(secret, signing_string))
|
||||
```
|
||||
|
||||
Verification rules:
|
||||
|
||||
- Reject if `|now - timestamp| > 300s` (replay window).
|
||||
- Constant-time compare (`hmac.compare_digest`).
|
||||
- Inbound verified with `inbound_secret`; outbound signed with
|
||||
`outbound_secret` (falls back to `inbound_secret`).
|
||||
- `signature_required: false` bypasses verification **and logs a warning** —
|
||||
intended only for local development behind a trusted network.
|
||||
|
||||
Reference (Python, ~6 lines):
|
||||
|
||||
```python
|
||||
import hmac, hashlib, time
|
||||
|
||||
def sign(secret: str, body: bytes, ts: int | None = None) -> tuple[str, str]:
|
||||
ts = ts or int(time.time())
|
||||
mac = hmac.new(secret.encode(), f"{ts}.".encode() + body, hashlib.sha256)
|
||||
return str(ts), "sha256=" + mac.hexdigest()
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 8. Delivery semantics & reliability
|
||||
|
||||
- **Inbound**: `202 Accepted` means *queued*, not *processed*. Use
|
||||
`X-LB-Idempotency-Key` to make client retries safe (dedup window, e.g. 10 min).
|
||||
- **Outbound**: **at-least-once**, best-effort. Retries on timeout/5xx with
|
||||
exponential backoff up to `callback_max_retries`. Callbacks for one
|
||||
`session_id` are delivered **in `sequence` order** (serialised per session);
|
||||
across sessions they may interleave.
|
||||
- **No persistence in v1**: if LangBot restarts mid-turn, in-flight callbacks
|
||||
may be lost. Durable replay is deferred (see §13). Callers needing exactly-once
|
||||
should dedup on `(session_id, reply_to, sequence)`.
|
||||
- **Backpressure**: the adapter must not block the pipeline on slow callbacks —
|
||||
outbound POSTs run on a per-session ordered queue with the configured timeout.
|
||||
|
||||
---
|
||||
|
||||
## 9. Optional: synchronous convenience mode (v1.1, behind a flag)
|
||||
|
||||
Some simple callers genuinely want "POST a message, get the reply in the HTTP
|
||||
response" and don't care about streaming/multi-part. We can offer an **opt-in**
|
||||
sync endpoint that internally waits for `is_final` and **collapses** all 1→M
|
||||
parts into one array:
|
||||
|
||||
```
|
||||
POST /bots/{bot_uuid}/sync → 200 { session_id, message: [ ...all parts concatenated... ] }
|
||||
```
|
||||
|
||||
Implemented by attaching a per-request future that resolves on the final reply,
|
||||
with a hard timeout. This is a **convenience wrapper** over the same machinery,
|
||||
explicitly documented as lossy for streaming/ordering. Not in v1 core.
|
||||
|
||||

|
||||
|
||||
## 10. Adapter implementation sketch (`platform/sources/http_bot.py`)
|
||||
|
||||
Implements `AbstractMessagePlatformAdapter`. Key methods:
|
||||
|
||||
```python
|
||||
class HttpBotAdapter(AbstractMessagePlatformAdapter):
|
||||
listeners: dict = pydantic.Field(default_factory=dict, exclude=True)
|
||||
|
||||
# --- inbound -------------------------------------------------------
|
||||
async def handle_unified_webhook(self, bot_uuid, path, request):
|
||||
body = await request.get_body()
|
||||
if self.config.get("signature_required", True):
|
||||
if not self._verify(request, body):
|
||||
return jsonify({"code": 40101, "msg": "invalid signature"}), 401
|
||||
data = json.loads(body)
|
||||
session_id = data["session_id"] # caller-defined identity
|
||||
session_type = data.get("session_type", self.config.get("default_session_type", "person"))
|
||||
chain = MessageChain.model_validate(data["message"])
|
||||
event = self._build_event(session_type, session_id, data.get("sender"), chain)
|
||||
# remember where to send replies for this session
|
||||
self._callback_for[session_id] = data.get("callback_url") or self.config.get("callback_url")
|
||||
# fire the registered listener → botmgr → msg_aggregator (N→1) → pipeline
|
||||
if type(event) in self.listeners:
|
||||
asyncio.create_task(self.listeners[type(event)](event, self))
|
||||
return jsonify({"code": 0, "msg": "accepted",
|
||||
"data": {"session_id": session_id, "accepted_message_id": event.message_id}}), 202
|
||||
|
||||
# --- outbound (called 1..M times per turn by the pipeline) ---------
|
||||
async def reply_message(self, message_source, message, quote_origin=False):
|
||||
return await self._post_callback(message_source, message, is_final=True, stream=False)
|
||||
|
||||
async def reply_message_chunk(self, message_source, bot_message, message,
|
||||
quote_origin=False, is_final=False):
|
||||
return await self._post_callback(message_source, message, is_final=is_final, stream=True)
|
||||
|
||||
async def is_stream_output_supported(self) -> bool:
|
||||
return True
|
||||
|
||||
def register_listener(self, event_type, func): self.listeners[event_type] = func
|
||||
def unregister_listener(self, event_type, func): self.listeners.pop(event_type, None)
|
||||
async def run_async(self): pass # nothing to poll; purely webhook-driven
|
||||
async def kill(self): pass
|
||||
```
|
||||
|
||||
`_post_callback` resolves the session's callback URL, assigns the next
|
||||
`sequence`, signs the body, and enqueues an ordered, retrying POST.
|
||||
|
||||
Session→callback mapping is kept in a small in-memory dict keyed by
|
||||
`session_id` (acceptable for v1; a turn's callback URL is captured at inbound
|
||||
time so replies always have a destination even if config later changes).
|
||||
|
||||
---
|
||||
|
||||
## 11. Security considerations
|
||||
|
||||
- **Inbound route is `AuthType.NONE`** at the framework level (same as all
|
||||
webhook adapters) — the adapter **must** enforce HMAC itself. Default
|
||||
`signature_required: true`.
|
||||
- **Timestamp window** (±300s) + idempotency key blunt replay.
|
||||
- **SSRF on callback_url**: validate scheme (`https` in prod), and consider an
|
||||
allow-list / block of private CIDRs since LangBot initiates the POST. Document
|
||||
this; enforce in code where feasible.
|
||||
- **Secret storage**: secrets live in the bot's `adapter_config` like every
|
||||
other adapter credential; surfaced as `type: string`/secret in the dashboard.
|
||||
- **One secret per bot** in v1. Per-caller key rotation / multiple keys is a
|
||||
future enhancement (§13).
|
||||
|
||||
---
|
||||
|
||||
## 12. Developer Experience (explicit deliverables)
|
||||
|
||||
The whole point of a standalone adapter is that **integrating is pleasant**. v1
|
||||
ships:
|
||||
|
||||
1. **`docs/platforms/http-bot.md`** — task-oriented integration guide:
|
||||
create the bot → copy inbound URL → set secret → stand up a callback
|
||||
endpoint → send first message → handle 1→M.
|
||||
2. **Copy-paste curl** for the first message (with a working signing one-liner).
|
||||
3. **Reference clients** (≤50 LOC each) in `examples/http-bot/`:
|
||||
`client.py` (push + a Flask/Quart callback receiver) and `client.ts`.
|
||||
4. **OpenAPI fragment** `docs/http-bot-openapi.json` describing inbound +
|
||||
callback shapes, so integrators can codegen.
|
||||
5. **Local echo recipe**: a one-command callback server that prints every
|
||||
reply, so a developer sees N→1 and 1→M working in under five minutes.
|
||||
6. **Postman/Hoppscotch collection** (nice-to-have).
|
||||
|
||||
DX acceptance check: *a developer who has never seen LangBot can, from the docs
|
||||
alone, push a message and observe a multi-part reply on their callback within
|
||||
10 minutes.*
|
||||
|
||||
### Quickstart (curl)
|
||||
|
||||
```bash
|
||||
BOT=https://your-langbot/bots/2f1c....
|
||||
SECRET=supersecret
|
||||
BODY='{"session_id":"ticket-10293","message":[{"type":"Plain","text":"hello"}]}'
|
||||
TS=$(date +%s)
|
||||
SIG="sha256=$(printf '%s.%s' "$TS" "$BODY" | openssl dgst -sha256 -hmac "$SECRET" -r | cut -d' ' -f1)"
|
||||
curl -sS -X POST "$BOT" \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "X-LB-Timestamp: $TS" \
|
||||
-H "X-LB-Signature: $SIG" \
|
||||
-d "$BODY"
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 13. Future work
|
||||
|
||||
- **Durable outbound queue** (persist + replay across restarts; exactly-once).
|
||||
- **Per-caller API keys** with rotation and scopes (multi-tenant Space usage).
|
||||
- **Sync convenience endpoint** (§9) once core is stable.
|
||||
- **Server-Sent Events outbound option** for callers that *do* want a stream but
|
||||
not a full duplex socket — single GET, server pushes chunks.
|
||||
- **Dashboard "test console"** for `http_bot` (send a message, watch callbacks)
|
||||
mirroring the existing WebSocket debug panel.
|
||||
|
||||

|
||||
|
||||
## 14. Rollout / task breakdown
|
||||
|
||||
| # | Task | Touches |
|
||||
|---|---|---|
|
||||
| 1 | `http_bot.yaml` manifest + icon | `platform/sources/` |
|
||||
| 2 | `HttpBotAdapter` (inbound verify, event build, outbound queue) | `platform/sources/http_bot.py` |
|
||||
| 3 | Signing helper module (shared) | `platform/sources/` or `utils/` |
|
||||
| 4 | i18n strings (en/zh/ja) | adapter yaml + web locale |
|
||||
| 5 | Integration docs `docs/platforms/http-bot.md` | `docs/` |
|
||||
| 6 | OpenAPI fragment + reference clients | `docs/`, `examples/http-bot/` |
|
||||
| 7 | Tests: signature verify, N→1 aggregation, 1→M ordering, retry | `tests/` |
|
||||
| 8 | (opt) SSRF guard for callback_url | adapter |
|
||||
|
||||
No changes required to: the unified webhook router, the aggregator, the query
|
||||
pool, or the pipeline. That is the design's main payoff.
|
||||
|
||||
---
|
||||
|
||||
## 15. Resolved decisions
|
||||
|
||||
1. **Callback URL trust** — **config-only.** The inbound message may not carry a
|
||||
`callback_url`; replies always go to the bot-config URL. Closes the SSRF
|
||||
vector where a leaked inbound secret could redirect replies.
|
||||
2. **Session lifecycle** — **`POST /bots/<uuid>/reset`** (body `{session_id,
|
||||
session_type?}`) drops the matching session from the session manager; the
|
||||
next message starts a fresh conversation. Implemented via sub-path routing in
|
||||
`handle_unified_webhook`.
|
||||
3. **Group semantics** — for `session_type: group`, `session_id` is the group/
|
||||
launcher id; `sender.id` (and optional `sender.group_name`) identify the
|
||||
member. A Space ticket maps to one `session_id`.
|
||||
4. **Backpressure** — bounded per-session outbound queue (maxlen 1000); on
|
||||
overflow the oldest reply is dropped and a warning logged, so a persistently
|
||||
down callback can never exhaust memory.
|
||||
|
||||
### Still open / deferred (see §13)
|
||||
|
||||
- Durable outbound queue (persist + replay across restarts).
|
||||
- Per-caller API keys with rotation/scopes for multi-tenant Space usage.
|
||||
- SSE outbound option and a dashboard test console.

# HTTP Bot Adapter — Integration Guide
|
||||
|
||||
Integrate **any backend system** with a LangBot pipeline over plain HTTP. Push
|
||||
messages in via a signed webhook; receive replies on a callback URL. No
|
||||
long-lived connection, full support for message **aggregation** (many inbound
|
||||
messages merged into one turn) and **multi-part replies** (one turn → many
|
||||
outbound messages).
|
||||
|
||||
This is the right adapter for **server-to-server** integrations — ticketing
|
||||
systems, CRMs, internal tools, custom web backends. (For an in-browser,
|
||||
real-time chat widget, use the embeddable Web Page Bot instead.)
|
||||
|
||||
> **5-minute goal:** stand up a callback receiver, send a message, and watch a
|
||||
> multi-part reply arrive — using the reference client in
|
||||
> [`examples/http-bot/`](../../examples/http-bot/).
|
||||
|
||||
---
|
||||
|
||||
## 1. Mental model
|
||||
|
||||
```
|
||||
Your backend ──(1) POST signed message──► LangBot /bots/<bot_uuid>
|
||||
(pipeline runs: aggregate → think → reply)
|
||||
Your callback ◄─(2) POST signed reply(s)── LangBot one POST per reply part
|
||||
```
|
||||
|
||||
- **(1) Inbound** is *fire-and-collect*: LangBot answers `202 Accepted`
|
||||
immediately and does **not** return the pipeline result on that response.
|
||||
- **(2) Outbound** replies arrive later as separate signed POSTs to your
|
||||
`callback_url`. A single turn may produce **several** callbacks (e.g. a tool
|
||||
call narration followed by the final answer).
|
||||
- Everything is keyed by a **`session_id` you choose** (e.g. a ticket number).
|
||||
Each `session_id` maps to one isolated LangBot conversation.
|
||||
|
||||
---
|
||||
|
||||
## 2. Create the bot
|
||||
|
||||
1. In the LangBot dashboard, add a bot and choose the **HTTP Bot** platform.
|
||||
2. Fill in the config:
|
||||
|
||||
| Field | Required | Notes |
|
||||
|---|---|---|
|
||||
| **Inbound Signing Secret** | yes | Your backend signs inbound requests with this. |
|
||||
| **Outbound Callback URL** | yes | Where LangBot POSTs replies. **Config-only** — cannot be overridden per message (SSRF protection). |
|
||||
| **Outbound Signing Secret** | no | LangBot signs callbacks with this; defaults to the inbound secret. |
|
||||
| **Default Session Type** | no | `person` (default) or `group`. |
|
||||
| **Require Inbound Signature** | no | Keep `true` in production. |
|
||||
| **Callback Timeout / Max Retries** | no | Defaults: 15s, 3 retries. |
|
||||
|
||||
3. Bind the bot to a **pipeline** and **enable** it.
|
||||
4. Copy the **Inbound Webhook URL** shown in the config — it looks like
|
||||
`https://your-langbot/bots/<bot_uuid>`.
|
||||
|
||||
---
|
||||
|
||||
## 3. The signature scheme
|
||||
|
||||
Both directions use the same dependency-free HMAC-SHA256 scheme:
|
||||
|
||||
```
|
||||
signing_string = "{timestamp}." + raw_body_bytes
|
||||
signature = "sha256=" + hex(HMAC_SHA256(secret, signing_string))
|
||||
```
|
||||
|
||||
Sent as headers:
|
||||
|
||||
| Header | Meaning |
|
||||
|---|---|
|
||||
| `X-LB-Timestamp` | Unix seconds. Rejected if more than **±300s** from server time. |
|
||||
| `X-LB-Signature` | `sha256=<hex>` over `"{timestamp}." + body`. |
|
||||
| `X-LB-Idempotency-Key` | *(optional, inbound)* dedup key; retries with the same key return `409`. |
|
||||
|
||||
Verify outbound callbacks the same way, using the **outbound** secret (or the
|
||||
inbound secret if you left it blank).
|
||||
|
||||
A six-line reference implementation is in `examples/http-bot/client.py`
|
||||
(`sign()` / `verify()`); a Node/TS version is in `client.ts`.
|
||||
|
||||
---
|
||||
|
||||
## 4. Send your first message (curl)
|
||||
|
||||
```bash
|
||||
BOT="https://your-langbot/bots/<bot_uuid>"
|
||||
SECRET="your-inbound-secret"
|
||||
BODY='{"session_id":"ticket-10293","message":[{"type":"Plain","text":"Export keeps failing on the dashboard."}]}'
|
||||
TS=$(date +%s)
|
||||
SIG="sha256=$(printf '%s.%s' "$TS" "$BODY" | openssl dgst -sha256 -hmac "$SECRET" -r | cut -d' ' -f1)"
|
||||
|
||||
curl -sS -X POST "$BOT" \
|
||||
-H "Content-Type: application/json" \
|
||||
-H "X-LB-Timestamp: $TS" \
|
||||
-H "X-LB-Signature: $SIG" \
|
||||
-d "$BODY"
|
||||
# -> 202 {"code":0,"msg":"accepted","data":{"session_id":"ticket-10293","accepted_message_id":"in_...","aggregating":true}}
|
||||
```
|
||||
|
||||
The reply(s) will be POSTed to your configured callback URL shortly after.
|
||||
|
||||
---
|
||||
|
||||
## 5. Inbound request format
|
||||
|
||||
`POST /bots/{bot_uuid}`
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"session_id": "ticket-10293", // REQUIRED. Your stable id. Maps 1:1 to a LangBot session.
|
||||
"session_type": "person", // optional: "person" | "group"; default from config
|
||||
"sender": { // optional metadata, surfaced to the pipeline/plugins
|
||||
"id": "user-5567",
|
||||
"name": "Alice"
|
||||
},
|
||||
"message": [ // REQUIRED. A LangBot MessageChain (array of segments).
|
||||
{ "type": "Plain", "text": "Export keeps failing on the dashboard." },
|
||||
{ "type": "Image", "url": "https://example.com/screenshot.png" }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
**Message segments.** Text uses `{"type":"Plain","text":"..."}`. Images use
|
||||
`{"type":"Image","url":"..."}` (or `base64`). Other supported types: `Voice`,
|
||||
`File`, `At`, `Quote`.
|
||||
|
||||
> Note: the callback URL is **not** accepted in the body — it is taken only from
|
||||
> bot config. This is deliberate (prevents an attacker who obtains the inbound
|
||||
> secret from redirecting replies to an arbitrary host).
|
||||
|
||||
### Aggregation (N → 1)
|
||||
|
||||
If your pipeline has **message aggregation** enabled, send several messages with
|
||||
the **same `session_id`** within the aggregation window and they are merged into
|
||||
**one** pipeline turn. No special flag — just reuse the `session_id`.
|
||||
|
||||
---
|
||||
|
||||
## 6. Outbound callback format
|
||||
|
||||
LangBot POSTs each reply part to your `callback_url`:
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"session_id": "ticket-10293", // echoes the inbound session
|
||||
"reply_to": "in_01H...", // the accepted_message_id this answers
|
||||
"sequence": 1, // 1-based ordinal within this turn
|
||||
"is_final": false, // true on the last part of the turn
|
||||
"stream": false, // true for streamed chunks
|
||||
"message": [ { "type": "Plain", "text": "Looking into it…" } ],
|
||||
"timestamp": "2026-06-22T09:00:01Z"
|
||||
}
|
||||
```
|
||||
|
||||
Your endpoint should return `2xx` quickly. Non-2xx / timeout → LangBot retries
|
||||
with exponential backoff (up to `callback_max_retries`).
|
||||
|
||||
### Multi-part replies (1 → M)
|
||||
|
||||
One turn may emit multiple callbacks, delivered **in `sequence` order** for a
|
||||
given session:
|
||||
|
||||
```
|
||||
seq=1 is_final=false "Checking your export logs…"
|
||||
seq=2 is_final=false "Found 2 failed exports."
|
||||
seq=3 is_final=true "Fixed — please try again."
|
||||
```
|
||||
|
||||
Stitch by `session_id` + `sequence`; the turn is complete when
|
||||
`is_final: true` arrives.
|
||||
|
||||
---
|
||||
|
||||
## 7. Reset a session
|
||||
|
||||
Start a fresh conversation for a `session_id` (drops history):
|
||||
|
||||
```
|
||||
POST /bots/{bot_uuid}/reset
|
||||
{ "session_id": "ticket-10293", "session_type": "person" }
|
||||
→ 200 { "code":0, "msg":"reset", "data": { "session_id":"ticket-10293", "removed": true } }
|
||||
```
|
||||
|
||||
Signed exactly like an inbound message.
|
||||
|
||||
---
|
||||
|
||||
## 8. Synchronous convenience mode
|
||||
|
||||
If you don't need streaming/multi-part and just want one reply back on the same
|
||||
HTTP call, POST to `/sync`. LangBot waits for the turn to finish and returns all
|
||||
parts **collapsed** into one array:
|
||||
|
||||
```
|
||||
POST /bots/{bot_uuid}/sync
|
||||
{ "session_id": "ticket-10293", "message": [ { "type":"Plain", "text":"hi" } ] }
|
||||
→ 200 { "code":0, "msg":"ok",
|
||||
"data": { "session_id":"ticket-10293", "reply_to":"in_...",
|
||||
"message": [ {"type":"Plain","text":"..."}, ... ] } }
|
||||
```
|
||||
|
||||
This is **lossy** (you lose `sequence` / streaming boundaries) and blocks up to
|
||||
`callback_timeout × 4` seconds. Prefer the callback model for anything
|
||||
real-time or multi-part. Only one in-flight `/sync` per `session_id`.
|
||||
|
||||
---
|
||||
|
||||
## 9. Error envelope
|
||||
|
||||
```jsonc
|
||||
{ "code": 40101, "msg": "invalid signature: signature_mismatch", "data": null }
|
||||
```
|
||||
|
||||
| HTTP | code | meaning |
|
||||
|---|---|---|
|
||||
| 202 | 0 | accepted |
|
||||
| 400 | 40001 | malformed body / missing `session_id` or `message` |
|
||||
| 401 | 40101 | bad/expired signature |
|
||||
| 409 | 40901 | duplicate idempotency key |
|
||||
| 413 | 41301 | message too large (>1 MiB) |
|
||||
| 500 | 50001 | internal error |
|
||||
|
||||
---
|
||||
|
||||
## 10. Try it end-to-end in 5 minutes
|
||||
|
||||
```bash
|
||||
cd examples/http-bot
|
||||
pip install flask requests
|
||||
|
||||
# Terminal 1 — your callback receiver (point the bot's callback_url here, e.g. via a tunnel):
|
||||
python client.py serve --port 8900 --secret SHARED_SECRET
|
||||
|
||||
# Terminal 2 — push a message:
|
||||
python client.py push \
|
||||
--url https://your-langbot/bots/<bot_uuid> \
|
||||
--secret SHARED_SECRET \
|
||||
--session ticket-1 \
|
||||
--text "hello"
|
||||
```
|
||||
|
||||
Watch Terminal 1 print each reply part (`[part ]` / `[FINAL]`) with its
|
||||
sequence number — that's 1→M working, signatures verified.
|
||||
|
||||
A machine-readable contract is in
|
||||
[`docs/http-bot-openapi.json`](../http-bot-openapi.json).
|
||||
|
||||
---
|
||||
|
||||
## 11. Security checklist
|
||||
|
||||
- Keep **Require Inbound Signature** on in production.
|
||||
- Use **HTTPS** callback URLs; the URL is config-only (no per-message override).
|
||||
- Treat the secrets like passwords; rotate via the dashboard.
|
||||
- The inbound route is unauthenticated at the framework level **by design** —
|
||||
security comes entirely from the HMAC signature, so never disable it on a
|
||||
public deployment.

# MCP Resources PR #2215 Review
|
||||
|
||||
> 更新日期: 2026-06-29
|
||||
> 分支: `mcp_resources`
|
||||
> PR: langbot-app/LangBot#2215
|
||||
> 主题: MCP Resources 在 LangBot 中的产品价值、AgentRunner 集成方式与后续架构方向
|
||||
|
||||
## 结论
|
||||
|
||||
PR #2215 对 LangBot 有明确价值：它补齐了 MCP 协议中 Resources 这一重要能力，让 MCP server 不再只暴露 tools，也可以暴露文档、代码片段、配置、日志、图片等上下文资源。管理端可以发现和预览资源，Agent 也可以通过当前实现按需列出和读取资源。
|
||||
|
||||
但当前 AgentRunner 层的接入方式更接近一个可用的第一阶段方案，而不是最终架构。现在 MCP Resources 被包装成两个 synthetic tools：
|
||||
|
||||
- `langbot_mcp_list_resources`
|
||||
- `langbot_mcp_read_resource`
|
||||
|
||||
这让模型可以通过 function calling 主动探索资源，落地成本低，也复用了已有 `ToolManager` / `LocalAgentRunner` 的工具调用链路。不过从 MCP 规范和主流实现来看，Resources 更适合作为一种一等上下文来源，而不是长期隐藏在工具列表里。
|
||||
|
||||
建议保留当前 synthetic tools 作为探索能力，同时把后续主线设计调整为：MCP Resources 是 pipeline / conversation / message 级别可选择、可固定、可审计的上下文输入。
|
||||
|
||||
## 当前实现判断
|
||||
|
||||
当前 AgentRunner 集成路径如下：
|
||||
|
||||
```text
|
||||
Pipeline 绑定 MCP server
|
||||
-> query.variables['_pipeline_bound_mcp_servers']
|
||||
-> Preproc 为 local-agent 加载工具
|
||||
-> ToolManager.get_all_tools()
|
||||
-> MCPLoader 注入 synthetic resource tools
|
||||
-> LocalAgentRunner 将工具 schema 传给模型
|
||||
-> 模型发起 list/read tool call
|
||||
-> ToolManager.execute_func_call()
|
||||
-> MCPLoader 调 MCP session.list_resources/read_resource
|
||||
-> tool result 回灌给模型
|
||||
```
|
||||
|
||||
这个路径的优点是：
|
||||
|
||||
- 复用现有工具调用机制，改动范围小。
|
||||
- Agent 可以按需探索资源，不需要每轮预先读取所有资源。
|
||||
- 可以沿用 pipeline 绑定的 MCP server 范围，避免越权读取未绑定 server。
|
||||
- 对已有 MCP tools 行为影响较小。
|
||||
|
||||
主要问题是：
|
||||
|
||||
- Resources 在语义上被降级成 tools，和 MCP 规范里的 resource primitive 不完全一致。
|
||||
- 模型必须先理解并主动调用 `list/read`，资源不会自然成为上下文。
|
||||
- pipeline 不能配置“默认携带某些资源”或“本轮附加某些资源”。
|
||||
- UI 资源 tab 目前是管理端预览能力，和 Agent 上下文选择没有打通。
|
||||
- 对 blob、图片、大文件、结构化资源的处理还比较粗糙。
|
||||
- 缺少 resource templates、订阅更新、缓存、chunk、token budget、trace 与审计策略。
|
||||
|
||||
## 主流项目做法
|
||||
|
||||
### MCP 官方规范
|
||||
|
||||
MCP Resources 是 server 暴露上下文数据的协议能力。规范没有要求 resources 必须以 tool call 形式给模型使用，而是把如何选择、过滤、读取和纳入上下文交给 Host application。
|
||||
|
||||
这意味着比较正统的集成方式是：LangBot 作为 Host，在 pipeline、会话或消息层决定哪些 resources 进入模型上下文。
|
||||
|
||||
参考: https://modelcontextprotocol.io/specification/2025-06-18/server/resources
|
||||
|
||||
### VS Code Copilot
|
||||
|
||||
VS Code 把 MCP Resources 做成 chat context 的一部分。用户可以通过 `Add Context > MCP Resources` 或命令浏览 MCP resources，并把选中的资源附加到一次 chat request。
|
||||
|
||||
这是目前最值得 LangBot 参考的产品形态：资源不是模型工具，而是用户和 Host 可控的上下文附件。
|
||||
|
||||
参考: https://code.visualstudio.com/docs/agent-customization/mcp-servers
|
||||
|
||||
### Anthropic SDK
|
||||
|
||||
Anthropic 的 client-side MCP helpers 提供资源读取和转换能力，例如把 MCP resource 转为 Claude message content 或 file。也就是说，应用先读取 resource，再显式放进模型消息。
|
||||
|
||||
这同样是 application-owned context injection，而不是把 resource 伪装成模型工具。
|
||||
|
||||
参考: https://platform.claude.com/docs/en/agents-and-tools/mcp-connector
|
||||
|
||||
### LangChain MCP Adapters
|
||||
|
||||
LangChain 把 MCP Resources 更像 data loader / document input 来处理，可以把资源加载成 `Blob`，再进入 LangChain 的文档、检索或上下文处理链路。
|
||||
|
||||
这说明 Resources 很适合作为知识源、文档源或上下文源，而不只是即时工具调用。
|
||||
|
||||
参考: https://docs.langchain.com/oss/python/langchain/mcp
|
||||
|
||||
### OpenAI Agents SDK
|
||||
|
||||
OpenAI Agents SDK 主路径仍偏向 MCP tools，但底层 MCP server API 已经有 `list_resources`、`list_resource_templates`、`read_resource` 等能力。当前形态说明 resources 是 client 能力，但并未默认变成 agent-visible tools。
|
||||
|
||||
参考: https://openai.github.io/openai-agents-python/mcp/
|
||||
|
||||
### Cline
|
||||
|
||||
Cline 会拉取 MCP tools、resources、resourceTemplates、prompts，并通过类似 `access_mcp_resource` 的内置访问方式让模型读取资源。这个方向和 LangBot 当前 synthetic tools 比较接近。
|
||||
|
||||
这种模式适合让 Agent 自主探索，但更像 Host 自定义的模型访问协议，不应成为唯一集成路径。
|
||||
|
||||
参考: https://github.com/cline/cline/blob/main/src/services/mcp/McpHub.ts
|
||||
|
||||
## 建议架构方向
|
||||
|
||||
### 1. 保留探索型工具
|
||||
|
||||
保留当前两个 synthetic tools：
|
||||
|
||||
- `langbot_mcp_list_resources`
|
||||
- `langbot_mcp_read_resource`
|
||||
|
||||
它们适合处理“用户没有显式选择资源，但 Agent 判断需要探索 MCP server 上下文”的场景。后续可以优化工具描述、返回格式、资源大小限制和错误信息。
|
||||
|
||||
### 2. 增加一等 Resource Context
|
||||
|
||||
新增一个 Host 层资源上下文概念，例如：
|
||||
|
||||
```text
|
||||
PipelineResourceBinding
|
||||
ConversationResourceAttachment
|
||||
MessageResourceAttachment
|
||||
```
|
||||
|
||||
Preproc 或独立的 `ResourceContextProvider` 在模型调用前读取这些资源，按 MIME 类型、大小、token budget 转为模型可消费的上下文。
|
||||
|
||||
### 3. 打通 UI 与 Agent 上下文
|
||||
|
||||
当前 MCP 详情页的 Resources tab 可以继续作为资源发现和预览入口。建议增加操作：
|
||||
|
||||
- 添加到本轮上下文
|
||||
- 固定到当前 pipeline
|
||||
- 固定到当前 bot / conversation
|
||||
- 查看资源读取历史和错误
|
||||
|
||||
这样 UI 资源管理能力才能真正影响 Agent 行为。
|
||||
|
||||
### 4. 支持 resource templates
|
||||
|
||||
MCP resource templates 允许 server 暴露参数化资源，例如：
|
||||
|
||||
```text
|
||||
repo://{owner}/{repo}/file/{path}
|
||||
log://{service}/{date}
|
||||
```
|
||||
|
||||
LangBot 后续应支持模板发现、参数填写、实例化和绑定。否则只能使用静态 resources，覆盖面会受限。
|
||||
|
||||
### 5. 增加资源处理策略
|
||||
|
||||
建议补齐：
|
||||
|
||||
- 文本资源 token budget 与截断策略。
|
||||
- 大文件 chunk 与摘要策略。
|
||||
- 图片/blob 的模型能力判断与 fallback。
|
||||
- MIME 类型白名单与安全限制。
|
||||
- 缓存与过期策略。
|
||||
- `resources/listChanged` 或订阅更新。
|
||||
- resource read trace，便于审计 Agent 读取了什么上下文。
|
||||
|
||||
## 推荐落地顺序
|
||||
|
||||
### Phase 1: 完成当前 PR 可用性
|
||||
|
||||
- 保留 synthetic tools。
|
||||
- 明确文档说明当前 Agent 集成是 tool-mediated。
|
||||
- 完善资源工具描述，降低模型误用概率。
|
||||
- 给 read/list 增加大小限制和更清晰的 MIME 处理。
|
||||
- 前端 Resources tab 与 Tools tab 分离，保持管理端清晰。
|
||||
|
||||
### Phase 2: 做 Host-owned context attachments
|
||||
|
||||
- 在 pipeline 或 conversation 层新增 resource attachment 配置。
|
||||
- Preproc 读取已绑定 resources，注入模型上下文。
|
||||
- UI 支持“添加到上下文 / 固定到 pipeline”。
|
||||
- 记录每轮实际注入的 resource URI 和 token 消耗。
|
||||
|
||||
### Phase 3: 做完整 MCP Resources 能力
|
||||
|
||||
- 支持 resource templates。
|
||||
- 支持资源订阅更新。
|
||||
- 支持 chunk、summary、RAG 化接入。
|
||||
- 为 DifyAgentRunner、LocalAgentRunner 等不同 runner 定义统一资源上下文接口。
|
||||
|
||||
## 最终建议
|
||||
|
||||
PR #2215 可以作为 MCP Resources 的第一阶段实现继续推进。它让 LangBot 快速拥有“资源发现、预览、按需读取”的闭环，也给 Agent 探索资源提供了可运行路径。
|
||||
|
||||
但在正式设计上，不建议把 “Resources == Tools” 固化为长期抽象。LangBot 更应该把 MCP Resources 定位为上下文来源，与 tools、prompts、knowledge base 并列：
|
||||
|
||||
```text
|
||||
Tools -> Agent 可以执行的动作
|
||||
Resources -> Host/用户/Agent 可以选择的上下文数据
|
||||
Prompts -> 可复用的任务模板
|
||||
Knowledge -> 可检索、可索引的长期知识
|
||||
```
|
||||
|
||||
这样既尊重 MCP 协议语义，也能让 LangBot 在 Agent 工作流、企业知识接入和多 MCP server 管理上走得更稳。

# HTTP Bot Adapter — Reference Clients
|
||||
|
||||
> English | [中文](./README.zh.md)
|
||||
|
||||
Minimal, dependency-light clients for the LangBot **HTTP Bot** platform adapter.
|
||||
They show the whole loop: signing a request, pushing a message, and receiving
|
||||
multi-part replies on a callback endpoint.
|
||||
|
||||
Full guide: [docs.langbot.app — HTTP Bot](https://docs.langbot.app/en/usage/platforms/http-bot).
|
||||
Machine-readable contract: [`docs/http-bot-openapi.json`](../../docs/http-bot-openapi.json).
|
||||
|
||||
## Files
|
||||
|
||||
| File | What it is |
|
||||
|---|---|
|
||||
| `playground.py` | **Interactive browser debug console** — a single-file web app you open in a browser to chat with a running `http_bot` bot and watch signing / 202 / callbacks live. Zero extra deps. |
|
||||
| `client.py` | Python client + Flask callback receiver (`pip install flask requests`). |
|
||||
| `client.ts` | TypeScript/Node 18+ client + callback receiver, **zero deps** (`npx tsx client.ts`). |
|
||||
|
||||
All three implement the identical HMAC-SHA256 scheme
|
||||
(`sha256=hex(HMAC(secret, "{timestamp}." + body))`) — verified byte-for-byte
|
||||
against the adapter.
|
||||
|
||||
## Interactive playground (recommended first run)
|
||||
|
||||
A self-contained web console: type a message in your browser, it is signed and
|
||||
POSTed to a **running** `http_bot` bot, and the bot's replies stream back into
|
||||
the page — with a debug panel showing the signature, the `202` ack, and each
|
||||
callback's `sequence` / signature-verification.
|
||||
|
||||
```bash
|
||||
# From the LangBot repo root, with the backend already running:
|
||||
PUBLIC_IP=<your-host-ip> ./.venv/bin/python examples/http-bot/playground.py
|
||||
# then open http://<your-host-ip>:8920/
|
||||
```
|
||||
|
||||
On startup it reads the LangBot API key + the `http_bot` bot from
|
||||
`data/langbot.db`, and configures that bot (inbound/outbound secret +
|
||||
`callback_url`) to point back at itself via the LangBot API — the bot reloads
|
||||
live, no restart needed. Requirements: an enabled `http_bot` bot bound to a
|
||||
working pipeline, and port `8920` reachable from your browser.
|
||||
|
||||
Env knobs: `PUBLIC_IP` (default `127.0.0.1`), `PLAYGROUND_PORT` (default `8920`).
|
||||
|
||||
## Headless clients
|
||||
|
||||
```bash
|
||||
# Python — Terminal 1: callback receiver (your callback_url target)
|
||||
python client.py serve --port 8900 --secret SHARED_SECRET
|
||||
|
||||
# Python — Terminal 2: push a message
|
||||
python client.py push --url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET --session ticket-1 --text "hello"
|
||||
|
||||
# blocking sync mode
|
||||
python client.py sync --url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET --session ticket-1 --text "hello"
|
||||
|
||||
# reset a session
|
||||
python client.py reset --url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET --session ticket-1
|
||||
```
|
||||
|
||||
```bash
|
||||
# TypeScript (Node 18+)
|
||||
npx tsx client.ts serve 8900 SHARED_SECRET
|
||||
npx tsx client.ts push https://your-langbot/bots/<BOT_UUID> SHARED_SECRET ticket-1 "hello"
|
||||
```
|
||||
|
||||
When the bot replies, the receiver prints each part with its `sequence` and an
|
||||
`[FINAL]` marker on the last one — that's the 1→M multi-reply model in action.
|
||||
|
||||
> The bot's `callback_url` must be reachable from LangBot. For local testing,
|
||||
> expose your receiver with a tunnel (cloudflared / ngrok) and set that URL in

# HTTP Bot 适配器 —— 参考客户端
|
||||
|
||||
> [English](./README.md) | 中文
|
||||
|
||||
面向 LangBot **HTTP Bot** 平台适配器的极简、低依赖客户端示例。
|
||||
它们完整展示了整条链路:对请求签名、推送一条消息、在回调端点接收
|
||||
1→M 的多段回复。
|
||||
|
||||
完整指南:[docs.langbot.app —— HTTP Bot](https://docs.langbot.app/zh/usage/platforms/http-bot)。
|
||||
机器可读的接口契约:[`docs/http-bot-openapi.json`](../../docs/http-bot-openapi.json)。
|
||||
|
||||
## 文件清单
|
||||
|
||||
| 文件 | 是什么 |
|
||||
|---|---|
|
||||
| `playground.py` | **浏览器交互式调试台** —— 单文件 Web 应用,在浏览器里和一个运行中的 `http_bot` bot 对话,实时观察签名 / 202 / 回调。零额外依赖。 |
|
||||
| `client.py` | Python 客户端 + Flask 回调接收端(`pip install flask requests`)。 |
|
||||
| `client.ts` | TypeScript/Node 18+ 客户端 + 回调接收端,**零依赖**(`npx tsx client.ts`)。 |
|
||||
|
||||
三者实现完全一致的 HMAC-SHA256 签名方案
|
||||
(`sha256=hex(HMAC(secret, "{timestamp}." + body))`)—— 已与适配器逐字节比对验证。
|
||||
|
||||
## 交互式 playground(推荐先跑这个)
|
||||
|
||||
一个自包含的 Web 控制台:在浏览器里输入消息,它会被签名并 POST 给一个
|
||||
**运行中**的 `http_bot` bot,bot 的回复会流式回到页面上 —— 调试面板会显示
|
||||
签名、`202` 确认,以及每条回调的 `sequence` / 签名验证结果。
|
||||
|
||||
```bash
|
||||
# 在 LangBot 仓库根目录、后端已启动的前提下:
|
||||
PUBLIC_IP=<你的主机IP> ./.venv/bin/python examples/http-bot/playground.py
|
||||
# 然后打开 http://<你的主机IP>:8920/
|
||||
```
|
||||
|
||||
启动时它会从 `data/langbot.db` 读取 LangBot API key 和 `http_bot` bot,
|
||||
并通过 LangBot API 把该 bot 配好(入站/出站密钥 + `callback_url`)指回自己 ——
|
||||
bot 会热加载,无需重启。前提:有一个已启用、绑定了可用 pipeline 的
|
||||
`http_bot` bot,且端口 `8920` 能从你的浏览器访问到。
|
||||
|
||||
可调环境变量:`PUBLIC_IP`(默认 `127.0.0.1`)、`PLAYGROUND_PORT`(默认 `8920`)。
|
||||
|
||||
## 无头客户端
|
||||
|
||||
```bash
|
||||
# Python —— 终端 1:回调接收端(你的 callback_url 指向它)
|
||||
python client.py serve --port 8900 --secret SHARED_SECRET
|
||||
|
||||
# Python —— 终端 2:推送一条消息
|
||||
python client.py push --url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET --session ticket-1 --text "hello"
|
||||
|
||||
# 阻塞式同步模式
|
||||
python client.py sync --url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET --session ticket-1 --text "hello"
|
||||
|
||||
# 重置一个会话
|
||||
python client.py reset --url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET --session ticket-1
|
||||
```
|
||||
|
||||
```bash
|
||||
# TypeScript(Node 18+)
|
||||
npx tsx client.ts serve 8900 SHARED_SECRET
|
||||
npx tsx client.ts push https://your-langbot/bots/<BOT_UUID> SHARED_SECRET ticket-1 "hello"
|
||||
```
|
||||
|
||||
当 bot 回复时,接收端会逐条打印,带上各自的 `sequence`,并在最后一条标记
|
||||
`[FINAL]` —— 这就是 1→M 多段回复模型的实际效果。
|
||||
|
||||
> bot 的 `callback_url` 必须能从 LangBot 访问到。本地测试时,可用隧道
|
||||
> (cloudflared / ngrok)把你的接收端暴露出去,并把那个 URL 填进 bot 配置。

"""LangBot HTTP Bot adapter — reference client (Python).

Two things in one file:
|
||||
|
||||
1. ``push()`` / ``push_sync()`` — send a message into a LangBot ``http_bot`` bot.
|
||||
2. A tiny Flask callback receiver that verifies signatures and prints replies,
|
||||
so you can watch N->1 aggregation and 1->M multi-reply working live.
|
||||
|
||||
Usage
|
||||
-----
|
||||
pip install flask requests
|
||||
|
||||
# Terminal 1 — start the callback receiver (this is your callback_url):
|
||||
python client.py serve --port 8900 --secret SHARED_SECRET
|
||||
|
||||
# Terminal 2 — push a message (async; reply lands on the receiver):
|
||||
python client.py push \
|
||||
--url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET \
|
||||
--session ticket-10293 \
|
||||
--text "Export keeps failing on the dashboard."
|
||||
|
||||
# Or push and block for the collapsed reply (sync convenience mode):
|
||||
python client.py sync --url https://your-langbot/bots/<BOT_UUID> \
|
||||
--secret SHARED_SECRET --session ticket-10293 --text "hi"
|
||||
|
||||
The signing scheme is HMAC-SHA256 over ``"{timestamp}." + raw_body``; see
|
||||
``sign()`` below — it is intentionally tiny and easy to port.

"""LangBot HTTP Bot — interactive playground (public, browser-based).
|
||||
|
||||
This is a REAL end-to-end demo against the RUNNING LangBot instance on this
|
||||
host. It is NOT a mock and NOT an in-process import: every message you type in
|
||||
the browser is signed and POSTed to the live `http_bot` bot at
|
||||
http://127.0.0.1:5300/bots/<uuid>, and the bot's replies come back to this
|
||||
server's /callback endpoint over real HTTP, then stream to your browser via SSE.
|
||||
|
||||
What it does on startup:
|
||||
1. Reads the LangBot API key + the http_bot bot from data/langbot.db.
|
||||
2. Configures the bot via the LangBot API (PUT /api/v1/platform/bots/<uuid>):
|
||||
sets inbound_secret + outbound_secret + callback_url to point back here.
|
||||
(LangBot reloads the bot live — no server restart needed.)
|
||||
3. Serves a chat page on 0.0.0.0:<PORT> so you can open it from the internet.
|
||||
|
||||
Run: ./.venv/bin/python examples/http-bot/playground.py
|
||||
Then open: http://<this-host-public-ip>:<PORT>/

# Page Bot Adapter — Embed Demo
|
||||
|
||||
> English | [中文](./README.zh.md)
|
||||
|
||||
A single self-contained HTML page that demos the LangBot **Page Bot**
|
||||
(`web_page_bot`) embeddable chat widget — the one you drop onto any website with
|
||||
a single `<script>` tag.
|
||||
|
||||
Full guide: [docs.langbot.app — Page Bot](https://docs.langbot.app/en/usage/platforms/webpage).
|
||||
|
||||
## Files
|
||||
|
||||
| File | What it is |
|
||||
|---|---|
|
||||
| `index.html` | **Browser demo** — open it, point it at a running LangBot instance + a Page Bot you created, and it loads the live embed widget so you can chat with the bot exactly as a site visitor would. Zero deps, no build step. |
|
||||
|
||||
## How to use
|
||||
|
||||
1. In the LangBot WebUI, create a bot with the **Page Bot** (`页面机器人`)
|
||||
adapter and bind it to a working pipeline. Copy its **bot UUID** from the
|
||||
generated embed code.
|
||||
2. Open `index.html` in a browser. Any of these work:
|
||||
- double-click the file, or
|
||||
- serve the folder: `python3 -m http.server 8930` then open
|
||||
`http://localhost:8930/examples/web-page-bot/`.
|
||||
3. Fill in:
|
||||
- **LangBot base URL** — where your instance is reachable from the browser
|
||||
(e.g. `http://localhost:5300`, or your public address).
|
||||
- **Page Bot UUID** — from step 1.
|
||||
- **Widget title** — optional, sets the `data-title` attribute.
|
||||
4. Click **Load widget**. A floating chat bubble appears in the bottom-right
|
||||
corner — click it and chat.
|
||||
|
||||
The page also renders the exact `<script>` snippet you'd paste into your own
|
||||
site (before `</body>`), and updates it live as you edit the fields.
|
||||
|
||||
## What it demonstrates
|
||||
|
||||
- The embed contract: `<script data-title="…" src="<base>/api/v1/embed/<uuid>/widget.js"></script>`.
|
||||
- `widget.js` is served by LangBot pre-configured for that bot UUID — title,
|
||||
bubble icon, language and optional Cloudflare Turnstile protection all come
|
||||
from the bot's config, no page changes needed.
|
||||
- Messages travel over a WebSocket to the bot's bound pipeline; replies stream
|
||||
back into the bubble.
|
||||
|
||||
> The widget loads `widget.js` from your LangBot instance, so the **base URL
|
||||
> must be reachable from the browser** you open this page in. If LangBot runs on
|
||||
> a server, use its public address instead of `localhost`.

# 页面机器人适配器 —— 嵌入演示
|
||||
|
||||
> [English](./README.md) | 中文
|
||||
|
||||
一个自包含的单文件 HTML 页面，用于演示 LangBot **页面机器人**
|
||||
(`web_page_bot`) 的可嵌入聊天组件 —— 也就是你用一行 `<script>` 标签就能放到任意
|
||||
网站上的那个组件。
|
||||
|
||||
完整指南：[docs.langbot.app —— 页面机器人](https://docs.langbot.app/zh/usage/platforms/webpage)。
|
||||
|
||||
## 文件清单
|
||||
|
||||
| 文件 | 是什么 |
|
||||
|---|---|
|
||||
| `index.html` | **浏览器演示页** —— 打开它，填上一个运行中的 LangBot 实例地址 + 你创建的页面机器人，它就会加载真实的嵌入组件，让你像网站访客一样和机器人对话。零依赖，无需构建。 |
|
||||
|
||||
## 使用方法
|
||||
|
||||
1. 在 LangBot WebUI 中，用 **页面机器人**（`web_page_bot`）适配器创建一个机器人，
|
||||
并绑定一个可用的流水线。从生成的嵌入代码里复制它的 **机器人 UUID**。
|
||||
2. 在浏览器中打开 `index.html`，以下任一方式皆可：
|
||||
- 直接双击该文件；或
|
||||
- 起一个静态服务：`python3 -m http.server 8930`，然后打开
|
||||
`http://localhost:8930/examples/web-page-bot/`。
|
||||
3. 填写：
|
||||
- **LangBot base URL** —— 你的实例在该浏览器中可访问的地址
|
||||
（例如 `http://localhost:5300`，或你的公网地址）。
|
||||
- **页面机器人 UUID** —— 第 1 步里复制的。
|
||||
- **组件标题** —— 可选，对应 `data-title` 属性。
|
||||
4. 点击 **Load widget**。页面右下角会出现一个浮动聊天气泡 —— 点开即可对话。
|
||||
|
||||
页面还会实时渲染出你需要粘贴到自己网站（放在 `</body>` 前）的那段 `<script>`
|
||||
代码，并随着你编辑输入框同步更新。
|
||||
|
||||
## 它演示了什么
|
||||
|
||||
- 嵌入契约：`<script data-title="…" src="<base>/api/v1/embed/<uuid>/widget.js"></script>`。
|
||||
- `widget.js` 由 LangBot 针对该机器人 UUID 预配置后下发 —— 标题、气泡图标、语言
|
||||
以及可选的 Cloudflare Turnstile 防护，全部来自机器人配置，无需改动页面。
|
||||
- 消息通过 WebSocket 发往机器人绑定的流水线，回复流式回到气泡中。
|
||||
|
||||
> 组件会从你的 LangBot 实例加载 `widget.js`，因此 **base URL 必须能从你打开本页
|
||||
> 的浏览器访问到**。如果 LangBot 部署在服务器上，请用它的公网地址而非
|
||||
> `localhost`。

## README & i18n convention (enforced on the marketplace)
|

|

A plugin published to LangBot Space serves a localized README on its detail page.
|
||||
The resolver (`langbot-space` `PluginService.GetPluginREADME`) works like this:
|

|

- **Root `README.md` MUST be in English.** It is the default and the fallback —
|
||||
when no per-language README matches the viewer's locale, the page serves the
|
||||
root `README.md`. A non-English root README makes the English/default view show
|
||||
the wrong language.
|
||||
- **All other languages live under `readme/README_{lang}.md`** — e.g.

`readme/README_zh_Hans.md`, `readme/README_ja_JP.md`. The 8 supported locales:

"""HTTP Bot adapter — standalone server-to-server platform adapter.
|
||||
|
||||
Lets any external backend drive a LangBot pipeline over plain HTTP:
|
||||
|
||||
* **Inbound** — the backend POSTs a signed message to the unified webhook
|
||||
route ``POST /bots/<bot_uuid>``; this adapter verifies the signature, builds
|
||||
a platform event carrying the caller-defined ``session_id`` as the launcher
|
||||
id, and fires it into the normal pipeline (so message aggregation, N->1,
|
||||
works for free).
|
||||
* **Outbound** — every ``reply_message`` / ``reply_message_chunk`` the pipeline
|
||||
emits is delivered as a signed POST to the configured ``callback_url``. A
|
||||
single turn may emit many replies (1->M); each is one callback, ordered per
|
||||
session via a small worker queue.
|
||||
|
||||
Design notes:
|
||||
|
||||
* The callback URL is taken **only** from adapter config (never from the
|
||||
inbound message) to keep the SSRF surface closed.
|
||||
* Replies for one ``session_id`` are delivered in ``sequence`` order; the
|
||||
caller knows a turn is complete when ``is_final: true`` arrives.
|
||||
* No new HTTP route is registered — the existing unified webhook dispatcher
|
||||
(``pkg/api/http/controller/groups/webhooks.py``) calls
|
||||
``handle_unified_webhook`` on this adapter.
|
||||

||||
