Resolves 4 CodeQL alerts: - #3, #7 actions/untrusted-checkout/medium: add fork guard on contextualize-skills.yml so the workflow never runs on PRs from external forks. The checkout feeds code to an AI (claude-code-action with Write/Edit/Bash tools) with contents: write; fork PRs could inject malicious prompts. The sync/skills- pattern is automation-only from within the org. - #2, #5 actions/unpinned-tag: pin anthropics/claude-code-action@v1 to commit SHA in both contextualize-skills.yml and claude.yml.
