CI/CD health specialist, Python/GitHub Actions only — failing CI runs, build times, test matrices, caching, SHA pinning. NOT for ruff/mypy config (foundry:linting-expert), PyPI release/CHANGELOG (oss:shepherd), non-GitHub-Actions platforms. TRIGGER: failing CI runs, slow builds, caching/SHA-pinning questions. SKIP: no GitHub Actions content.

Fetches all GitHub API data for a repo (REST + GraphQL) in two parallel groups; writes raw JSONL for oss:repo-warden axis scorers. TRIGGER when: spawned by /oss:analyse (vitality mode) to fetch raw GitHub data. NOT for axis scoring or report generation. NOT for direct user invocation.

Scores an assigned group of vitality axes from a pre-fetched DATA_FILE using vitality-scoring.md; writes partial scores JSON for /oss:analyse assembly. TRIGGER when: spawned 3× in parallel by /oss:analyse (vitality mode) to score axis groups A, B, or C. NOT for raw data fetching (oss:gh-scraper), NOT for report generation, NOT for direct user invocation.

OSS shepherd, Python/ML/CV/AI — contributor communication (triage, reply/PR drafts), release coordination (SemVer, PyPI, CHANGELOG). NOT for docstrings/README (foundry:doc-scribe), CI/publish YAML (oss:cicd-steward), diff review (/oss:review), CHANGELOG gen (/oss:release). TRIGGER: triaging issues/PRs, SemVer. SKIP: posting to GitHub.

Analyze GitHub issues, Pull Requests (PRs), Discussions, and repo vitality for an Open Source Software (OSS) project. For any specific item, casts a wide net — finds and lists all related open and closed issues/PRs/discussions, explicitly flags duplicates. Summarizes long threads, extracts reproduction steps, and generates repo vitality stats. Uses gh Command Line Interface (CLI) for GitHub Application Programming Interface (API) access. Complements oss:shepherd (requires `oss` plugin). NOT for PR readiness assessment or code review (use oss:review). TRIGGER when: user provides GitHub issue number (#N), PR number, or github.com URL with issue/PR/discussion path AND asks to analyze, summarize, understand, or triage it; user asks for repo vitality stats or "is this repo healthy". SKIP: user already pasted full thread text inline; oss:resolve already active on same PR; user wants code review (use oss:review); user phrasing is "review PR" meaning code quality assessment, not thread triage (route to oss:review).

Prepare release communication and check readiness. Main mode: notes with optional flags --changelog, --summary, --migration; range as v1->v2. Other modes: prepare (full pipeline: audit → all artifacts), audit (pre-release readiness: blockers, docs alignment, version consistency, CVEs), demo (story-telling release notebook in jupytext # %% format). TRIGGER when: user requests release notes, CHANGELOG entry, migration guide, internal summary, release readiness audit, or release demo; phrases: 'draft release notes', 'prepare release', 'audit release readiness', 'generate CHANGELOG for v1->v2', 'release demo notebook'. SKIP: actual git tagging or PyPI/registry upload (use git tag, gh release create, twine upload directly); release communication for a non-Python project where this skill's pytest-centric audit assumptions do not apply; PR-level review (use /oss:review); thread/issue analysis (use /oss:analyse).

OSS maintainer fast-close workflow for GitHub PRs. Three phases: (1) PR intelligence — reads full thread, linked issues, PR body to synthesize contribution motivation and classify every comment into action items; (2) conflict resolution — checks out PR branch (fork-aware via gh pr checkout), merges BASE into it, resolves conflicts semantically using contributor's intent as priority lens; (3) implements each action item as separate attributed commit via Codex, pushes back to contributor's fork. Supports three source modes: pr (live GitHub comments only), report (latest /review report findings as action items, no GitHub re-fetch), and pr + report (both sources aggregated and deduplicated in one pass). Also accepts bare comment text for single-comment dispatch. NOT for reply drafting to /oss:analyse findings (use /oss:analyse --reply (requires `oss` plugin)). NOT for code diff review of PR changes (use /oss:review). NOT for release preparation (use /oss:release). NOT for fixing local bugs unrelated to a PR (use /develop:fix; requires develop plugin). TRIGGER when: PR is ready to close and has open comments, conflicts, or review findings to address; user says 'close this PR', 'resolve comments on PR #N', or 'implement review findings'.

Multi-agent code review of GitHub Pull Requests (Python source, documentation (Markdown/RST), and CI/CD config PRs) covering architecture, tests, performance, docs, lint, security, and API design. TRIGGER when: user provides a GitHub PR number (e.g. 42, #42) and asks to review/audit/check it, or provides a saved review-report path with --reply to draft a contributor-facing comment; phrases: 'review PR 123', 'audit this pull request', 'look at PR #42', 'draft a reply for this review report'. SKIP: local file or current git diff review (use /develop:review (requires 'develop' plugin)); non-Python source PRs without Python files (TypeScript-only, Go-only, Rust-only); standalone issue/discussion thread analysis (use /oss:analyse).
