A curated collection of skills, prompts, and workflows that extend Codex's capabilities — your personal grimoire for AI-powered development.
Skill Claude CodeCodex
REST API design patterns for resource naming, HTTP methods, status codes, pagination strategy, error envelopes, versioning, and rate limiting. Use when designing, reviewing, or refactoring HTTP APIs and endpoint contracts.
Skill Claude CodeCodex
Use when writing boto3 or AWS SDK v3 code — configuring IAM auth, reading/writing S3, designing DynamoDB access patterns, writing Lambda handlers, processing SQS batches, or troubleshooting credential and throttling errors.
Skill Claude CodeCodex
Use when implementing reliable message processing with Azure Service Bus — choosing between queues and topics, configuring peek-lock settlement, handling dead-lettered messages, or enforcing ordered processing with sessions.
Skill Claude CodeCodex
Use when writing Python code that integrates with Azure Blob Storage, AI Search, Document Intelligence, or Key Vault — or when configuring Managed Identity auth, designing a hybrid search index, or troubleshooting Azure SDK retry behavior.
Skill Claude CodeCodex
Use when adding or debugging caching in a service — choosing a cache strategy, designing TTLs, preventing stampedes, reasoning about invalidation, or configuring HTTP Cache-Control headers.
Skill Claude CodeCodex
Use when setting up or debugging GitHub Actions pipelines — adding quality gates, configuring OIDC cloud auth, building matrix test runs, publishing artifacts to GHCR/PyPI/npm, or promoting builds from staging to production.
Skill Claude CodeCodex
Use when building or debugging apps that call the Claude API — implementing tool use, streaming, vision, prompt caching, batch processing, extended thinking, or an agentic loop with the Anthropic SDK.
Skill Claude CodeCodex
Use when configuring Claude Code — installing skills or agents, writing hook configurations, setting up tool permissions, registering MCP servers, or authoring CLAUDE.md project instructions.
Skill Claude CodeCodex
Pull request review guidance for correctness, security, tests, performance, API contract drift, migrations, and error handling. Use when reviewing diffs, pull requests, or risky refactors.
Skill Claude CodeCodex
Authoritative reference for OpenAI Codex CLI's orchestration surface - skills discovery paths, agents/openai.yaml schema, hooks.json events and stdin JSON payload, notify config, and AGENTS.md precedence. Use when installing skills, wiring hooks, debugging why a skill or hook isn't firing, or explaining…
Skill Claude CodeCodex
Create or update Codex skills that follow the repository skill format, trigger cleanly, and stay concise. Use when adding a new skill, refining an existing SKILL.md, or converting domain guidance into an installable Codex skill package.
Skill Claude CodeCodex
Cross-language coding standards for Python, TypeScript, and Go covering naming, SOLID design, code smell removal, and comment philosophy. Use when writing, reviewing, or refactoring production code for maintainability.
Skill Claude CodeCodex
Use when building a RAG pipeline that ingests PDFs, Excel, CSV, or images — especially when debugging silent data loss, choosing between OCR tools, or handling edge cases like scanned pages, merged cells, or embedded charts.
Skill Claude CodeCodex
Use when writing Dockerfiles, setting up docker-compose for local dev, configuring Kubernetes resources (Deployment, Service, Ingress, HPA), sizing pod resource limits, or packaging a service with Helm.
Skill Claude CodeCodex
Use when building or debugging data pipelines with Airflow or Prefect, writing dbt models or tests, designing incremental loads, implementing idempotent ETL/ELT jobs, validating data quality, or orchestrating multi-step data workflows.
Skill Claude CodeCodex
Use when designing a schema, adding indexes to fix slow queries, writing a zero-downtime migration, diagnosing N+1 issues with EXPLAIN ANALYZE, or configuring connection pooling for a PostgreSQL-backed service.
Skill Claude CodeCodex
Database guidance for schema naming, safe migrations, indexing, N+1 detection, transaction scope, and soft-delete versus hard-delete tradeoffs. Use when designing schemas, writing migrations, or tuning persistence behavior.
Skill Claude CodeCodex
Use when choosing a deployment strategy for a release, setting up canary or blue/green rollouts, adding feature flags to decouple deployment from release, coordinating a zero-downtime database migration, or defining rollback criteria and procedures.
Skill Claude CodeCodex
Use when choosing a branching strategy, writing a commit message, opening or reviewing a pull request, setting up commit linting, or tagging a versioned release.
Skill Claude CodeCodex
Containerization guidance for multi-stage builds, non-root execution, dockerignore hygiene, layer caching, healthchecks, and secret handling. Use when writing or reviewing Dockerfiles and container images.
Skill Claude CodeCodex
End-to-end (E2E) testing patterns for user journeys, browser automation, UI state, and production-like environment validation. Use when testing the system as a black box from the user's perspective.
Skill Claude CodeCodex
Use when designing or debugging an event-driven system — choosing Kafka partitioning strategies, implementing the outbox pattern, handling dead-letter queues, ensuring idempotent consumers, or making event sourcing decisions.
Skill Claude CodeCodex
Use when structuring a FastAPI application, designing dependency injection chains, defining Pydantic v2 schemas, adding JWT authentication, or writing async route tests with httpx.
Skill Claude CodeCodex
Use when adding feature flag support to a service, designing a percentage-based rollout, setting up A/B experiments or multivariate tests, choosing between LaunchDarkly, Unleash, and OpenFeature, writing tests for flag-gated code, or managing flag lifecycle and cleanup.
