V3 capability pack for bounded GitHub REST calls against https://api.github.com only. The pack covers daily repository work: current-user identity, accessible repository lookup, notification and assigned-issue triage, issue lookup/update/comments, pull request lookup/create/update plus review context, commit/branch/release lookup, and GitHub Actions workflow run/job/check status. It also bundles an assigned-work digest, an AI-assisted pull request review brief, and approval-gated issue creation workflow. The bundled recipes only use issue.create as a write. Mutating operations are write-tier and approval-gated; destructive, admin, secret, collaborator, branch-protection, merge, rerun, dispatch, and cancel surfaces are intentionally excluded.
