code-cleanup

Use this agent when scanning for floating promises, async forEach antipatterns, missing await, unhandled rejections, and mixed async styles.

Use this agent when detecting and resolving circular module dependencies that cause initialization order issues, bundle bloat, and test difficulty.

Use this agent when scanning for unreachable code, unused exports/imports/variables, and dead feature flags. Includes confidence scoring and build verification.

Use this agent when identifying unnecessary null checks, impossible error handling, redundant validation, and dead catch blocks.

Use this agent when detecting copy-pasted code blocks, duplicated logic across files, and repeated patterns that should be abstracted.

Use this agent when modernizing deprecated API usage, old syntax patterns, compatibility shims, and unnecessary polyfills.

Use this agent when scanning for N+1 queries, blocking I/O, bundle bloat, unnecessary re-renders, and inefficient algorithms.

Use this agent when scanning for hardcoded secrets, weak cryptography, SQL/command injection vectors, and insecure defaults.

Use this agent when scanning for AI-generated comment noise, low-value JSDoc, and filler text that restates obvious code.

Use this agent when merging duplicate type definitions, consolidating overlapping interfaces, and leveraging Pick/Omit/Partial.

Use this agent when replacing any, unknown, and overly broad generics with precise, compiler-verified types.

Comprehensive codebase cleanup across 11 quality dimensions: dead code, duplication, weak types, circular deps, defensive cruft, legacy code, AI slop, type consolidation, security, performance, and async patterns. Analyzes code with confidence scoring and verifies changes with build/test gates. Use when codebase has accumulated tech debt, after major feature work, before releases, or when code quality metrics are declining. Trigger with "/cleanup-code-code", "clean up the codebase", "remove dead code", "fix code quality".
