catlog22 29a1fea467 feat: Add templates for epics, product brief, and requirements documentation
- Introduced a comprehensive template for generating epics and stories in Phase 5, including an index and individual epic files.
- Created a product brief template for Phase 2 to summarize product vision, goals, and target users.
- Developed a requirements PRD template for Phase 3, outlining functional and non-functional requirements, along with traceability matrices.

feat: Implement tech debt roles for assessment, execution, planning, scanning, validation, and analysis

- Added roles for tech debt assessment, executor, planner, scanner, validator, and analyst, each with defined phases and processes for managing technical debt.
- Each role includes structured input requirements, processing strategies, and output formats to ensure consistency and clarity in tech debt management.

# State Diagnoser
Diagnose root causes of UI issues: state management problems, event binding failures, async handling errors.
## Phase 2: Context & Complexity Assessment
1. Load scan report from `<session>/artifacts/scan-report.md`
2. Load scanner state via `team_msg(operation="get_state", session_id=<session-id>, role="scanner")`
### Wisdom Input
1. Read `<session>/wisdom/patterns/ui-feedback.md` and `<session>/wisdom/patterns/state-management.md` if available
2. Use patterns to identify root causes of UI interaction issues
3. Reference `<session>/wisdom/anti-patterns/common-ux-pitfalls.md` for common causes
3. Assess issue complexity:
| Complexity | Criteria | Strategy |
|------------|----------|----------|
| High | 5+ issues, cross-component state | CLI delegation |
| Medium | 2-4 issues, single component | CLI for analysis |
| Low | 1 issue, simple pattern | Inline analysis |
### Complex Analysis (use CLI)
For complex multi-file state management issues:
```
Bash(`ccw cli -p "PURPOSE: Analyze state management patterns and identify root causes
CONTEXT: @<issue-files>
EXPECTED: Root cause analysis with fix recommendations
CONSTRAINTS: Focus on reactive update patterns" --tool gemini --mode analysis`)
```
## Phase 3: Root Cause Analysis
For each issue from scan report:
### State Management Diagnosis
| Pattern | Root Cause | Fix Strategy |
|---------|------------|--------------|
| Array.splice/push | Direct mutation, no reactive trigger | Use filter/map/spread for new array |
| Object property change | Direct mutation | Use spread operator or reactive API |
| Missing useState/ref | No state tracking | Add state variable |
| Stale closure | Captured old state value | Use functional setState or ref.current |
### Event Binding Diagnosis
| Pattern | Root Cause | Fix Strategy |
|---------|------------|--------------|
| onClick without handler | Missing event binding | Add event handler function |
| Async without await | Unhandled promise | Add async/await or .then() |
| No error catching | Uncaught exceptions | Wrap in try/catch |
| Event propagation issue | stopPropagation missing | Add event.stopPropagation() |
### Async Handling Diagnosis
| Pattern | Root Cause | Fix Strategy |
|---------|------------|--------------|
| No loading state | Missing async state tracking | Add isLoading state |
| No error handling | Missing catch block | Add try/catch with error state |
| Race condition | Multiple concurrent requests | Add request cancellation or debounce |
## Phase 4: Diagnosis Report
1. Generate root cause analysis for each issue and write to `<session>/artifacts/diagnosis.md`
### Wisdom Contribution
If new root cause patterns discovered:
1. Write diagnosis patterns to `<session>/wisdom/contributions/diagnoser-patterns-<timestamp>.md`
2. Format: Symptom, root cause, detection method, fix approach
3. Share state via team_msg:
```
team_msg(operation="log", session_id=<session-id>, from="diagnoser",
type="state_update", data={
diagnosed_issues: <count>,
pattern_types: {
state_management: <count>,
event_binding: <count>,
async_handling: <count>
}
})
```
