Top Use Cases (30 total)

FastAPI Application Bootstrap (UC-001)

Provides the main FastAPI application entry point with CORS middleware, dependency injection wiring, and runtime service initialization for the Hermes Triggers: api, server, start

Server Authentication Service (UC-005)

Provides single-user server authentication helpers including token encoding, decoding, expiration checking, and HMAC signature validation for securing Triggers: auth, authentication, token

Setup Engine Pattern Detection (UC-014)

Detects chart patterns (VCP, Cup-with-Handle, NR7, etc.) using normalized scoring and cross-detector calibration for trade setup quality assessment Triggers: setup, pattern, vcp

For all 30 use cases, see references/USE_CASES.md.

Execute trigger: When user intent matches intent_router.uc_entries[].positive_terms AND user uses action verb (run/execute/跑/执行/backtest/fetch/collect)

What I'll Ask You

• Target market: A-share (default), HK, or crypto? (US stocks in ZVT are half-baked — stockus_nasdaq_AAPL exists but coverage is thin)
• Data source / provider: eastmoney (free, no account), joinquant (account+paid), baostock (free, good history), akshare, or qmt (broker)?
• Strategy type: MACD golden-cross, MA crossover, volume breakout, fundamental screen, or custom factor?
• Time range: start_timestamp and end_timestamp for backtest period
• Target entity IDs: specific stocks (stock_sh_600000) or index components (SZ1000)?
