# Code Cleanup

## Overview

Performs post-review cosmetic cleanup to make code production-ready. This is the final workflow step after `/developer-kit-specs:specs.task-review` approval.

**Input**: `docs/specs/[id]/tasks/TASK-XXX.md` (reviewed status)  
**Output**: Cleaned code, task marked `completed`

## When to Use

- Use when asked to clean up code, polish, finalize, tidy up, or remove technical debt after review approval.
- Use to prepare code for completion: remove debug logs, dead code, optimize imports, and improve readability.
- Use as the final quality gate in the specification-driven development workflow.
- Not for refactoring logic or fixing bugs — focused solely on cosmetic and hygiene cleanup.

## Arguments

| Argument | Required | Description |
|----------|----------|-------------|
| `--lang` | No | `java`, `spring`, `typescript`, `nestjs`, `react`, `python`, `general` |
| `--task` | Yes | Path to task file |

## Best Practices

- **Clean, not change**: Only remove or reorganize — never change functionality
- **Preserve behavior**: Code must work exactly the same after cleanup
- **Use project tools**: Prefer `./mvnw spotless:apply`, `npm run lint:fix`, `black`, etc.
- **Use TodoWrite**: Track progress through all 8 phases
- **Stop on failure**: If tests fail, stop and report — do not proceed

See `references/language-patterns.md` for language-specific formatter commands, import ordering, and grep patterns.

## Instructions

### Phase 1: Task Verification

1. Parse `$ARGUMENTS` for parameters:
   - `--lang` (optional): Target language/framework
   - `--task` (required): Task ID or file path
   - `--spec` (optional): Spec folder path (used with task ID)
   
   **Support two formats**:
   - Format 1 (direct path): `--task=docs/specs/001-feature/tasks/TASK-001.md`
   - Format 2 (spec+task): `--spec=docs/specs/001-feature --task=TASK-001`
   
   If Format 2 is used, construct the task file path as: `{spec}/tasks/{task}.md`

2. Read the task file. Verify:
   - Status is `reviewed` or `implemented` (not `completed`)
   - Review report `TASK-XXX--review.md` exists and is approved
3. If not reviewed → stop and tell user to run `/developer-kit-specs:specs.task-review` first
4. Extract task ID, title, and `provides` files

### Phase 2: Identify Files to Clean

1. Read `TASK-XXX--review.md` for files created/modified
2. Read task `provides` field for file paths
3. Verify files exist; build cleanup list
4. Categorize: source files, test files, config files

### Phase 3: Technical Debt Removal

Search files for temporary/debug artifacts with Grep:
- `console.log`, `System.out.println`, `print(`, `// DEBUG:`, `// temp`, `// hack`
- Resolved `TODO`/`FIXME` comments (keep unresolved ones)

Review context for each finding. Remove confirmed debt and document what was removed.

### Phase 4: Import Optimization

1. Run language-specific import optimizer if available (see references)
2. Manually remove unused imports if no tool exists
3. Document files changed

### Phase 5: Code Readability Improvements

1. Run language-specific formatter if available (see references)
2. If no formatter: fix indentation, break long lines (>120), fix spacing
3. Remove dead code only if obviously safe
4. Document changes

### Phase 6: Documentation Verification

1. Verify class/file headers and public API docs
2. Check remaining TODOs are still valid and have context
3. Remove or update outdated comments
4. Document documentation changes

### Phase 7: Final Verification

1. Run linters if available
2. Run tests if available
3. Verify no logic or signature changes were introduced
4. If tests fail → stop and report failures

### Phase 8: Task Completion

1. **Auto-update task status**:
   - Add a `## Cleanup Summary` section to the task file
   - Check any remaining boxes in the DoD section
   - Hooks automatically update status to `completed` and set `completed_date` + `cleanup_date`
   
2. Append `## Cleanup Summary` to task file with:
   - Files cleaned
   - Changes made
   - Verification checklist (linters, tests, no functionality changes)
3. Mark all todos complete

## Examples

### Spring Boot Cleanup

```bash
/developer-kit-specs:specs-code-cleanup --lang=spring --task="docs/specs/001-user-auth/tasks/TASK-001.md"
```

Actions:
1. Verify TASK-001 status is `reviewed`
2. Files: `UserController.java`, `UserService.java`, `UserRepository.java`
3. Remove 5 `System.out.println` and 2 resolved TODOs
4. Run `./mvnw spotless:apply`
5. Run `./mvnw test -q`
6. Mark task `completed`

### TypeScript Cleanup

```bash
/developer-kit-specs:specs-code-cleanup --lang=typescript --task="docs/specs/002-dashboard/tasks/TASK-003.md"
```

Actions:
1. Verify TASK-003 status is `reviewed`
2. Files: `Dashboard.tsx`, `useDashboard.ts`, `Dashboard.test.tsx`
3. Remove 8 `console.log` statements
4. Run `npm run lint:fix` and `npm run format`
5. Run `npm test`
6. Mark task `completed`

## Constraints and Warnings

- Never change logic or signatures during cleanup
- Stop immediately and report if tests fail
- Verify behavior is unchanged before marking complete
