…po PRs (CodeQL) - Pin anthropics/claude-code-action@v1 -> @e90deca # v1.0.171 in both contextualize-skills.yml and claude.yml. Fixes 2x actions/unpinned-tag. - Harden contextualize-skills against actions/untrusted-checkout: the job checks out the PR head and runs Claude Code over it WITH the ANTHROPIC_API_KEY secret, contents: write, and pull-requests: write, then pushes commits back. Add an explicit `head.repo.full_name == github.repository` guard so a fork PR can never reach this privileged, secret-bearing path. Combined with the existing sync/skills- branch filter, only the internal skills-sync automation triggers it. claude.yml was already least-privilege (contents: read; gated on author_association OWNER/MEMBER/COLLABORATOR) and needed only the pin. The 2 untrusted-checkout alerts are dismissed (won't fix) with this compensating control as the documented reason. Refs PIN-24. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
