REST API conventions — consistent naming, proper HTTP methods/status codes, pagination, versioning, error responses, and type-safe contracts.
Skill Claude CodeCodex
Breaking change detection, versioning strategies (URL path vs header), deprecation policies, backward compatibility rules, and OpenAPI spec maintenance.
Skill Claude CodeCodex
Schema design, migrations, indexing, naming conventions, and query performance. Prevents N+1 queries, missing indexes, and irreversible schema changes.
Skill Claude CodeCodex
Apply distributed systems patterns including idempotency, saga pattern, outbox pattern, eventual consistency, and CQRS to build reliable, consistent distributed services.
Skill Claude CodeCodex
Structured logging, request tracing, health checks, error tracking, and key metrics. Every service should be observable from day one.
Skill Claude CodeCodex
Bundle size limits, API response time budgets, query limits, image optimization, lazy loading, and caching strategies.
Skill Claude CodeCodex
Apply resilience patterns (circuit breakers, bulkheads, retries, timeouts, graceful degradation, DLQs) to distributed services to prevent cascading failures and maintain availability under partial outages.
Skill Claude CodeCodex
Evaluate and apply the Twelve-Factor App methodology with modern 2025 interpretations. Covers all 12 factors with actionable checks for cloud-native applications running on containers, Kubernetes, and serverless platforms.
Skill Claude CodeCodex
Use when the user wants Codex to review Claude's work, cross-validate PRs, or run high-volume PR review with dual-model verification using the codex-plugin-cc plugin.
Skill Claude CodeCodex
Run independent agents concurrently for unrelated tasks. Maximizes throughput when tasks have no shared state.
Skill Claude CodeCodex
Process code review feedback with technical verification — not performative agreement. Fix real issues, push back on incorrect feedback with evidence.
Skill Claude CodeCodex
Invoke the code-reviewer agent with git-based commit ranges to get structured feedback on code quality, architecture compliance, and correctness.
Skill Claude CodeCodex
Dispatch fresh subagents per task with precisely crafted instructions. Two-stage review (spec compliance + code quality) ensures high-quality output.
Skill Claude CodeCodex
Detects project type, analyzes existing patterns, generates architecture specifications, and maintains architectural consistency across sessions. The key innovation that turns CLAUDE.md-style contracts into automatic, evolving project specifications.
Skill Claude CodeCodex
Automatically generates a lightweight specification before code starts flowing. Captures what the user wants, what will be built, acceptance criteria, and constraints — in a single invisible pass. Skipped for Quick Fixes. Invisible for Builder tier, presented for Engineer tier.
Skill Claude CodeCodex
Structured gap analysis that identifies what a project is missing — not what's done poorly (that's /audit), but what's absent entirely. Checks for tests, CI, security basics, linting, type safety, deployment readiness, and dependency health. Each finding has a severity and a concrete fix action.
Skill Claude CodeCodex
Master routing skill — loaded at every session start. Defines skill priority hierarchy, mandatory invocation rules, user experience tiers, task size awareness, and routes to appropriate skills based on task type.
Skill Claude CodeCodex
4-phase root cause investigation — observe, hypothesize, test, implement. Prevents trial-and-error debugging and enforces a 3-fix limit before reassessment.
Skill Claude CodeCodex
JSDoc/docstrings on exports, README sync, API documentation, architecture decision records, and changelog entries.
Skill Claude CodeCodex
WCAG 2.1 AA baseline — semantic HTML, ARIA labels, color contrast, keyboard navigation, screen reader compatibility, and focus management.
Skill Claude CodeCodex
Component patterns, state management, styling conventions, and rendering strategies for modern frontend development.
Skill Claude CodeCodex
Self-improving loop — after completing work, sub-agents analyze the conversation to extract signals (corrections, improvised steps, what worked first try, what failed). Proposes updates to project learnings and skill effectiveness. Every session makes the next one better.
Skill Claude CodeCodex
Use when creating a new skill for the Shipworthy plugin, or when a recurring failure mode needs to be codified into a reusable guide. Covers TDD-for-documentation, CSO (Claude Search Optimization), adversarial testing, and the full skill lifecycle.
Skill Claude CodeCodex
Pipeline design, environment configuration, secret management in CI, deployment rollback strategies, and feature flags for gradual rollout.
