Development

Reviews React/Vue component architecture, state, and hooks. Use when junior builds components, forms, modals, uses useState, useEffect, adds state, or asks "is this good React".

Guides error handling for async operations and API calls. Use when junior asks "what if this fails", "handle errors", "try catch", "network error", or builds features with fetch, promises, or external services.

Background knowledge for code quality. Applied when reviewing naming conventions, DRY, SOLID, function size, refactoring, or when junior asks "is this clean", "code review", "better way".

Guides documentation standards including READMEs, JSDoc, and code comments. Use when writing documentation, adding comments, or explaining code. Enforces "WHY not WHAT" principle.

Guides systematic debugging through Protocol D (READ, ISOLATE, DOCS, HYPOTHESIZE, VERIFY). Use when junior says "stuck", "not working", "broken", "bug", "error", "crashed", "failing", "can't figure out", or expresses frustration. Do NOT use for general questions.

Reviews API design, REST conventions, and backend architecture. Use when junior builds API endpoints, Express routes, middleware, controllers, or asks "is this RESTful", "check my endpoint".

Reviews accessibility including WCAG, ARIA, keyboard navigation. Use when junior builds forms, buttons, modals, interactive elements, or asks "is this accessible", "a11y", "screen reader".

Transforms completed work into STAR interview stories (Situation, Task, Action, Result). Use when completing tasks, preparing for behavioral interviews, or documenting achievements.

Transforms completed work into powerful resume bullet points with action verbs, technical context, and quantified impact. Use when completing tasks, updating portfolio, or preparing job applications.

A complex but safe skill for project scaffolding

A skill containing patterns that should NOT trigger false positives

Guide development using Kent Beck's TDD methodology. Use when implementing new features, fixing bugs, or adding rules to cc-audit. Enforces test-first approach with Red-Green-Refactor cycle.

This skill should be used when working with GitHub CLI (gh) for repository management, pull requests, issues, API access, GitHub Actions, or automation workflows. Provides comprehensive guidance on gh command patterns, security considerations, and best practices.

Advisory consultation skill for architectural reviews, design decisions, code analysis, and technology evaluation. Codex provides recommendations without making code changes. Invoked by phrases like "consult Codex", "get Codex's opinion", "ask Codex about", "have Codex review", "Codex analysis", "validate this approach", "brainstorm with Codex", or "Codex consensus".

Structural code search and rewriting using AST patterns. Use when user mentions "ast-grep", "sg", or needs to search codebases using Abstract Syntax Tree patterns, find specific code structures, perform complex queries beyond text search, or rewrite code at scale. Triggers on requests for pattern matching, code analysis, linting rules, or automated refactoring.

Android development with Kotlin Coroutines and Flow. Use when user mentions "coroutines", "suspend", "Flow", "StateFlow", "SharedFlow", "viewModelScope", "lifecycleScope", or needs to implement async programming, handle structured concurrency, integrate coroutines with Retrofit/Room/WorkManager, or write coroutine tests. Triggers on Android concurrency, async, or Flow tasks.

Android development with Kotlin and Jetpack Compose. Use when user mentions "Compose", "Jetpack Compose", "Material3", "Hilt", "Room", "ViewModel", or needs to build Android UI, implement MVVM architecture, manage Compose state, or integrate Jetpack libraries (Navigation, Room, Hilt, ViewModel). Triggers on Android/Compose/Kotlin development tasks.

Expert Android and Java reverse engineering for APK/AAR/JAR decompilation and inspection. Use when user mentions "decompile", "jadx", "apktool", "reverse engineer", or needs to analyze Android binaries, unpack libraries, understand obfuscated apps, or extract resources from compiled artifacts.
