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

-

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-code-cleanup --lang=spring --task="docs/specs/001-user-auth/tasks/TASK-001.md"

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-code-cleanup --lang=typescript --task="docs/specs/002-dashboard/tasks/TASK-003.md"

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
