Skill Claude CodeCodex
Stops execution and fixes root cause when commands, builds, scripts, or tools fail unexpectedly. Triggers on workaround language: 'directly', 'instead', 'alternatively', 'skip', 'fall back', 'work around', 'isn't working', 'broken', 'manually'. Activates on any unexpected non-zero exit code or process failure.
Command
Run full codebase review using automatic-code-review rules.
Skill Claude CodeCodex
Use when about to ask the user a factual question, propose a solution, diagnose an error, or choose between approaches. Triggers on: 'Do you have X installed?', 'What version?', 'Is X configured?', 'We should...', 'The fix is...', 'Options: 1...', 'Based on my understanding...', 'I believe X supports...'. Before…
Command
Analyze PR feedback patterns and suggest config updates to catch issues locally.
Skill Claude CodeCodex
This skill analyzes code for design quality improvements across 8 dimensions: Naming, Object Calisthenics, Coupling & Cohesion, Immutability, Domain Integrity, Type System, Simplicity, and Performance. Ensures rigorous, evidence-based analysis by: (1) Understanding code flow first via implementation-analysis protocol…
Skill Claude CodeCodex
This skill should be used when fixing bugs, implementing features, debugging issues, or making code changes. Ensures understanding of code flow before implementation by: (1) Tracing execution path with specific file:line references, (2) Creating lightweight text diagrams showing class.method() flows, (3) Verifying…
Skill Claude CodeCodex
FOLLOW THE STATE MACHINE IN SKILL.MD. When user says 'continue': (1) FIRST: Run pwd, (2) Announce STATE: CHECKSTATUS, (3) Read .claude/session.md to check Status field, (4) Route based on Status. NEVER auto-advance tasks. NEVER use TodoWrite. NEVER create git commits.
Skill Claude CodeCodex
Systematic debugging methodology that eliminates guessing and speculation. Add instrumentation to gather specific data that fully explains the problem. Evidence before hypothesis. Observation before solution. Triggers on: debugging, error investigation, 'why is this failing', unexpected behavior, test failures…
Agent
Challenge optimization proposals from multiple adversarial perspectives. Independently verify claims. Spawned as a teammate in the optimization team.
Agent
Research Claude Code capabilities and produce structured optimization proposals. Spawned as a teammate in the optimization team.
Skill Claude CodeCodex
Engage with what the user said before taking action. Triggers on: questions ('?'), feedback ('this is wrong', 'that doesn't look right', 'there are issues'), challenges ('why did you', 'have you considered'), criticism ('this isn't working', 'I don't like'), observations ('I notice', 'it seems like'), naming a skill…
Skill Claude CodeCodex
Enforces code organization using features/ (verticals), platform/ (horizontals), and shell/ (thin wiring). Triggers on: code organization, file structure, where does this belong, new file creation, refactoring.
Agent
Detect missing project context and opportunities to build new skills.
Agent
Detect wasted cycles, unnecessary back-and-forth, and misinterpretations in a session transcript.
Agent
Detect violations of loaded skills in a session transcript.
Agent
Detect unused tools, missed parallelism, and underutilized capabilities in a session transcript.
Command
Analyze a session transcript for optimization opportunities.
Skill Claude CodeCodex
Object-oriented design principles including object calisthenics, dependency inversion, fail-fast error handling, feature envy detection, and intention-revealing naming. Triggers on: writing new classes or functions, refactoring, code review, 'clean up', method longer than 10 lines, feature envy, primitive obsession…
Skill Claude CodeCodex
Quick persona switching. Triggers: 'switch persona', 'switch to X', 'become X'. Lists personas, reads selected file, switches immediately.
Skill Claude CodeCodex
Design, refactor, analyze, and review code by applying the principles and patterns of tactical domain-driven design. Triggers on: domain modeling, aggregate design, 'entity', 'value object', 'repository', 'bounded context', 'domain event', 'domain service', code touching domain/ directories, rich domain model…
Agent
Verify task completion before finishing work. Spawn with task ID, location, and work summary.
Command
Verify task completion with task-check agent.
Skill Claude CodeCodex
Strict test-driven development state machine with red-green-refactor cycles. Enforces test-first development, meaningful failures, minimum implementations, and full verification. Activates when user requests: 'use a TDD approach', 'start TDD', 'test-drive this'.
Command
Mark a report as resolved.
