Safe, phase-gated refactoring: CHARACTERIZE with tests, PLAN incremental steps, EXECUTE one change at a time, VALIDATE no regressions. Use when renaming functions/variables, extracting modules, changing signatures, restructuring directories, or consolidating duplicate code. Use for "refactor", "rename", "extract", "restructure", or "migrate pattern". Do NOT use for bug fixes or new feature implementation.
Run TypeScript type checking with tsc --noEmit and parse errors into actionable, file-grouped output. Use when validating TypeScript code before commits, after refactors, or when checking for type regressions. Use for "type check", "tsc", "TypeScript errors", "type validation", or pre-commit TypeScript verification. Do NOT use for linting, test execution, runtime errors, or JavaScript-only projects without tsconfig.json.
Analyze, consolidate, and document codebases through multi-perspective analysis. Use when reviewing project structure, planning refactoring, creating documentation, or assessing technical debt.
Clarity pre-deployment validation — syntax checking, deprecated keyword detection, sender check analysis, error propagation review, and test verification.
Diagnose and fix bugs with root-cause analysis and verification. Use when you have a concrete issue report, failing behavior, runtime error, or test regression that should be resolved safely. For ambiguous, high-risk, or broad-scope issues, stop and route to write-plan first.
CRITICAL: Use for performance optimization. Triggers: performance, optimization, benchmark, profiling, flamegraph, criterion, slow, fast, allocation, cache, SIMD, make it faster, 性能优化, 基准测试
PHP 8.5+ modern patterns, PSR standards, and SOLID principles. Use when reviewing PHP code, checking type safety, auditing code quality, or ensuring PHP best practices. Triggers on "review PHP", "check PHP code", "audit PHP", or "PHP best practices".
Run Intent validation and sync checks. Triggers intent-validate and intent-sync agents. Use /intent-check for full check, or /intent-check --validate/--sync for specific checks.
Comprehensive debugging methodology for finding and fixing bugs (formerly debugging). This skill should be used when debugging code, investigating errors, troubleshooting issues, performing root cause analysis, or responding to incidents. Covers systematic reproduction, hypothesis-driven investigation, and root cause analysis techniques. Use when encountering exceptions, stack traces, crashes, segfaults, undefined behavior, or when bug reports need investigation.
Transform approved Intent into executable phased plan with strict TDD. Each step requires tests first (happy/bad/edge/security cases), then implementation. Use after /intent-review when ready to start development.
Implements user stories, writes clean tested code, follows best practices. Trigger keywords implement story, dev story, code, implement, build feature, fix bug, write tests, code review, refactor
Detects common LLM coding agent artifacts in codebases. Identifies test quality issues, dead code, over-abstraction, and verbose LLM style patterns. Use when cleaning up AI-generated code or reviewing for agent-introduced cruft.
