Specs Code Cleanup Agent Skill

Code Cleanup

Overview

Performs post-review cosmetic cleanup to make code production-ready. This workflow is now integrated as Phase T-7 of /developer-kit-specs:specs.task-implementation. It can also be invoked manually using --action=cleanup.

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 |

| --action| No | Set to cleanup for manual invocation |

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

• 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

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

Phase 2: Identify Files to Clean

• Read TASK-XXX--review.md for files created/modified
• Read task provides field for file paths
• Verify files exist; build cleanup list
• 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

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

Phase 5: Code Readability Improvements

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

Phase 6: Documentation Verification

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• Remove or update outdated comments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

Phase 7: Final Verification

• Run linters if available
• Run tests if available
• Verify no logic or signature changes were introduced
• If tests fail → stop and report failures

Phase 8: Task Completion

• 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

• Append ## Cleanup Summary to task file with:
• Files cleaned
• Changes made
• Verification checklist (linters, tests, no functionality changes)
• Mark all todos complete

Examples

Spring Boot Cleanup

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

Actions:

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

TypeScript Cleanup

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

Actions:

• Verify TASK-003 status is reviewed
• Files: Dashboard.tsx, useDashboard.ts, Dashboard.test.tsx
• Remove 8 console.log statements
• Run npm run lint:fix and npm run format
• Run npm test
• 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
