Top Use Cases (19 total)

Cox Model Residual Analysis (UC-101)

Diagnosing Cox proportional hazards model fit by computing and visualizing martingale, deviance, and delta_beta residuals to identify outliers and inf Triggers: cox residuals, martingale residual, deviance residual

Time-Lagged Conversion Rate Analysis (UC-103)

Modeling marketing conversion rates where there is a time lag between initial contact and conversion event, requiring specialized survival analysis te Triggers: conversion rate, time-lagged, marketing

Piecewise Exponential Survival Models (UC-104)

Fitting piecewise exponential survival models that allow different hazard rates in different time intervals, useful when hazard is non-constant over t Triggers: piecewise exponential, varying hazard, breakpoints

For all 19 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)?

Semantic Locks (Fatal)

ID	Rule	On Violation
SL-01	Execute sell orders before buy orders in every trading cycle	halt
SL-02	Trading signals MUST use next-bar execution (no look-ahead)	halt
SL-03	Entity IDs MUST follow format entity_type_exchange_code	halt
SL-04	DataFrame index MUST be MultiIndex (entity_id, timestamp)	halt
SL-05	TradingSignal MUST have EXACTLY ONE of: position_pct, order_money, order_amount	halt
SL-06	filter_result column semantics: True=BUY, False=SELL, None/NaN=NO ACTION	halt
SL-07	Transformer MUST run BEFORE Accumulator in factor pipeline	halt
SL-08	MACD parameters locked: fast=12, slow=26, signal=9	halt
