# Blueprint Develop - Test-Driven Strategy Implementation

## Overview

Execute strategy implementation with TDD discipline and **Postmortem regression prevention**. Every code change must align with backtest interfaces, pass PM compliance checks, and have synchronized test coverage.

## Core Principle

```
./postmortem/ = 深度病历库 (Deep Case History)
./CLAUDE.md   = 高频手术准则 (High-Frequency Operating Rules)

Rule: 每写一行代码前，先查 CLAUDE.md；每改一个模块前，先查相关 postmortem
```

## When to Use

- Implementing new trading strategy logic from Linear tickets
- Modifying existing strategy code in `strategies/`
- User mentions "开发", "implement", or "code the strategy"
- Any code change that affects trading logic

**Do NOT use when:**
- Planning strategy (use `blueprint-plan` instead)
- Pure backtest runs without code changes
- Documentation or config changes only

## Prerequisites

Before invoking this skill, verify:
- [ ] Linear ticket exists for the work (from `blueprint-plan`)
- [ ] Backtest framework is in place (`backtest/` directory)
- [ ] Test file location confirmed (`tests/backtest_unit.py`)
- [ ] **PM mitigations from ticket identified** (from `blueprint-plan` Phase 0)

## Workflow

```dot
digraph blueprint_develop {
    rankdir=TB;
    node [shape=box];

    start [label="Start: Linear Ticket Ready" shape=ellipse];
    pm_load [label="0. Load PM Context\n(CLAUDE.md + postmortem/)" style=filled fillcolor=lightyellow];
    env [label="1. Environment Alignment\n(GitHub MCP)"];
    pm_test [label="2. PM Regression Tests First\n(TDD Red Phase)" style=filled fillcolor=lightyellow];
    test_first [label="3. Feature Tests\n(TDD Red Phase)"];
    impl [label="4. Atomic Implementation\n(code-simplifier)"];
    sync [label="5. Sync Test Update\n(TDD Green Phase)"];
    impact [label="6. Impact + PM Compliance\n(context7)"];
    done [label="Code Ready for Review" shape=ellipse];

    start -> pm_load;
    pm_load -> env;
    env -> pm_test;
    pm_test -> test_first;
    test_first -> impl
