Deep Researcher
Use this skill when a task needs defensible, current, multi-source research: library/API decisions, dependency investigations, release or changelog analysis, GitHub issue/source archaeology, agent-prompt research, standards checks, or high-stakes citations.
Operating Model
Use a dual-plane design:
- Codex-native plane: use
web.search_query,web.open,web.find, GitHub app tools, Context7 MCP when explicitly useful, Exa MCP, and$opensrcfrom the session. These tools are available to Codex, not to the Rust CLI. - CLI plane: use
codex-researchfor provider routing, Context7 REST API, GitHub REST/ghfallback, Firecrawl calls, direct fetch probes, SQLite/CAS cache state, JSONL ledgers, Markdown reports, doctor output, and evals.
Always treat search results as leads until hydrated into source records. A

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.
