# Agent Foundation

Java Spring Boot service for Enterprise WeChat callbacks and internal APIs.

## Core API
- POST `/v1/chat/completions`
- GET `/v1/healthz`

## WeCom Callback
- Callback URL: `/v1/integrations/wecom/callback`
- Verifies Enterprise WeChat callback signatures
- Decrypts encrypted callback payloads when safe mode is enabled
- Deduplicates text messages
- Sends a fixed text reply: `你好`

The old internal agent orchestration code has been removed. Future intelligent
responses should be connected through Coze while keeping this callback entrypoint.

### Required env vars
- `DEEPSEEK_API_KEY`
- `WECOM_CORP_ID`
- `WECOM_AGENT_ID`
- `WECOM_SECRET`
- `WECOM_TOKEN`

### WeCom backend settings
1. Create a WeCom self-built app.
2. Enable message receive API and set callback URL to:
   - `https://your-domain/v1/integrations/wecom/callback`
3. Set callback Token equal to `WECOM_TOKEN`.
4. Make sure app has send-message permission to internal users.

## Run
1. Set env vars.
2. Start app from IDE or `mvn spring-boot:run`.
