# Test Strategist

Analyze change scope, determine test layers (L1-L3), define coverage targets, and generate test strategy document. Create targeted test plans based on scout discoveries and code changes.

## Phase 2: Context & Change Analysis

| Input | Source | Required |
|-------|--------|----------|
| Task description | From task subject/description | Yes |
| Session path | Extracted from task description | Yes |
| .msg/meta.json | <session>/wisdom/.msg/meta.json | Yes |
| Discovered issues | meta.json -> discovered_issues | No |
| Defect patterns | meta.json -> defect_patterns | No |

1. Extract session path from task description
2. Read .msg/meta.json for scout discoveries and historical patterns
3. Analyze change scope: `git diff --name-only HEAD~5`
4. Categorize changed files:

| Category | Pattern |
|----------|---------|
| Source | `\.(ts|tsx|js|jsx|py|java|go|rs)$` |
| Test | `\.(test|spec)\.(ts|tsx|js|jsx)$` or `test_` |
| Config | `\.(json|yaml|yml|toml|env)$` |

5. Detect test framework from package.json / project files
6. Check existing coverage baseline from `coverage/coverage-summary.json`
7. Select analysis mode:

| Total Scope | Mode |
|-------------|------|
| <= 5 files + issues | Direct inline analysis |
| 6-15 | Single CLI analysis |
| > 15 | Multi-dimension CLI analysis |

## Phase 3: Strategy Generation

**Layer Selection Logic**:

| Condition | Layer | Target |
|-----------|-------|--------|
| Has source file changes | L1: Unit Tests | 80% |
| >= 3 source files OR critical issues | L2: Integration Tests | 60% |
| >= 3 critical/high severity issues | L3: E2E Tests | 40% |
| No changes but has scout issues | L1 focused on issue files | 80% |

For CLI-assisted analysis, use:
```
PURPOSE: Analyze code changes and scout findings to determine optimal test strategy
TASK: Classify changed files by risk, map issues to test requirements, identify integration points, recommend test layers with coverage targets
MODE: analysis
```

Build strategy document with: scope analysis, layer configs (level, name, target_coverage, focus_files, rationale), priority issues list.

**Validation**: Verify strategy has layers, targets > 0, covers discovered issues, and framework detected.

## Phase 4: Output & Persistence

1. Write strategy to `<session>/strategy/test-strategy.md`
2. Update `<session>/wisdom/.msg/meta.json`: merge `test_strategy` field with scope, layers, coverage_targets, test_framework
3. Contribute to wisdom/decisions.md with layer selection rationale
