Skill Claude CodeCodex
Use when auditing project structure, planning refactors, improving code organization, analyzing dependencies and module boundaries, or identifying structural issues. TypeScript/JavaScript-primary with language-agnostic patterns.
Skill Claude CodeCodex
Use when a completed task changed UI-affecting files and browser verification is needed during /work. Checks visual elements, interactions, and console errors in a real browser via Playwright. Not a standalone skill.
Skill Claude CodeCodex
Use when creating or debugging CI/CD pipelines, implementing deployment strategies (blue-green, canary, rolling), optimizing build times, reviewing pipeline security, or working with GitHub Actions, GitLab CI, CircleCI, Azure DevOps, or Bitbucket Pipelines.
Skill Claude CodeCodex
Use when provisioning cloud resources, choosing between AWS services (Lambda vs ECS vs EKS), writing CDK/IaC, designing serverless or container architectures, configuring IAM/security groups, or optimizing cloud costs.
Skill Claude CodeCodex
Use when designing database schemas, reviewing data models, planning migrations, optimizing slow queries, or establishing database patterns. Covers relational (PostgreSQL, MySQL, SQLite), document (MongoDB), and ORM-integrated (Prisma, Drizzle, TypeORM) projects.
Skill Claude CodeCodex
Use for multi-day technology evaluations, competitive analysis, architectural exploration, best practices research, or major strategic decisions requiring comprehensive investigation and stakeholder reports. Unlike spike (time-boxed hours), supports extended multi-day investigation.
Skill Claude CodeCodex
Use when creating READMEs, API docs, ADRs, or user guides. Provides templates and patterns for each documentation type. Dispatched by /work for docs-type tasks.
Skill Claude CodeCodex
Use when designing error hierarchies, implementing React error boundaries, adding retry logic or fallbacks, creating API error responses, integrating error tracking (Sentry), or improving user-facing error communication.
Skill Claude CodeCodex
Use when verifying feature completeness against PRD requirements, identifying gaps between backend implementation and user-facing accessibility, generating remediation tasks, or auditing across frameworks (Next.js, React Router, TanStack, React Native, Expo).
Skill Claude CodeCodex
Use after a task, story, epic, worktree, or development branch is implementation-complete and freshly verified. Presents merge, PR, keep, or discard choices and records evidence before cleanup.
Skill Claude CodeCodex
Use when adding logging to services, setting up monitoring, creating alerts, debugging production issues, designing SLIs/SLOs, or implementing structured logging (Pino, Winston), metrics (Prometheus, DataDog, CloudWatch), or distributed tracing (OpenTelemetry).
Skill Claude CodeCodex
Use when revising existing implementation plans, analyzing impact of task changes, exploring modifications to project scope or dependencies, or updating task hierarchies with full impact visibility before execution.
Skill Claude CodeCodex
Use when analyzing PRD documents, concept briefs, or feature specs to create implementation plans, breaking work into epics/stories/tasks with dependencies and estimates, or generating PROJECT.md and kanban tracking.
Skill Claude CodeCodex
Use when building TypeScript SDKs, extracting shared code into packages, creating developer tooling libraries, designing clean API surfaces, or publishing to npm (public or private). Covers typed clients, error handling, multi-target bundling (ESM/CJS/browser).
Skill Claude CodeCodex
Use when reviewing code security, auditing dependencies for CVEs, checking configuration or secret security, assessing authentication and authorization patterns, identifying OWASP vulnerabilities (injection, XSS, CSRF), or addressing security concerns about implementations.
