codex-sdk
Codex SDK + Codex CLI (master skill)
Build reliable, auditable, multi-step coding workflows that scale from a single run to multi-agent orchestration.
ExecPlans (durable planning)
For multi-hour work, keep intent durable across compaction/restarts using an ExecPlan:
- Contract:
references/execplans.md - Template + rules:
.agent/PLANS.md(usescripts/init_agent_workspace.pyto bootstrap a repo) - ExecPlan skeleton:
assets/templates/execplan.md(or generate a file withscripts/new_execplan.py)
Workflow decision tree
- Need a scriptable one-shot in CI or cron? → use
codex exec(references/codex-cli-exec.md) - Need a server-side app controlling Codex programmatically? → use
@openai/codex-sdk(references/codex-sdk-typescript.md) - Need multi-agent orchestration or dynamic tools? → run
codex mcp-serverand orchestrate via OpenAI Agents SDK (references/mcp-and-agents-sdk.md) - Need durability across runs (memory, caching, resumable state)? → persist run metadata and event logs in SQLite (
references/state-memory-sqlite.md)

World-class Vitest QA/test engineer for TypeScript + Next.js (local + CI performance focused)
8docker-architect
SOTA Docker/Compose architecture, implementation, refactor, and security hardening. Use when working on containerization tasks such as creating or rewriting Dockerfiles, docker-compose files, buildx/bake configs, .dockerignore, and CI pipelines for build/test/scan/publish; auditing existing container setups for security, correctness, size/perf, and best practices (least privilege, non-root, minimal images, pinned base images, BuildKit secrets, healthchecks); debugging Docker build/run issues; or designing dev vs prod compose workflows across services (DB/cache/queues) with correct networking, volumes, secrets, and resource limits.
7pytest-dev
World-class pytest engineer for Python: write/refactor tests, fix flakiness, design fixtures/markers, add coverage, speed up suites (collection/runtime), and optimize CI (GitHub Actions sharding, xdist parallelism, caching). Use when asked about pytest best practices, pytest 9.x features (subtests, strict mode, TOML config), pytest plugins (xdist/cov/asyncio/mock/httpx), or test performance/CI tuning.
