Agentic CI/CD: expand AI-powered drift detection org-wide

[JoeCardoso13]

Context

PR contributor-toolkit#36 introduces an AI-powered docs drift detection workflow using claude-code-action. It runs on PRs and flags when CLAUDE.md / README.md no longer match repo reality.

Once merged, this becomes the foundation for broader agentic CI/CD checks across the org.

Current state

• Workflow lives in contributor-toolkit/.github/workflows/docs-drift-check.yml
• Uses anthropics/claude-code-action@v1 with Sonnet
• Gated to JoeCardoso13 PRs only (cost control during experimentation)
• Uses a repo-level ANTHROPIC_API_KEY secret

Future directions

Short-term

• Verify the workflow works end-to-end after merging the PR that introduces it
• Evaluate the quality of drift detection on real PRs

Medium-term

• Move ANTHROPIC_API_KEY from repo secret to org secret
• Remove the user gate or replace with an org team check
• Adopt a reusable workflow so other repos can call one central definition

Long-term

• Cross-repo drift detection: e.g., PATTERNS.md in contributor-toolkit references conventions used in mcp-server-template-python / mcp-server-template-typescript — detect when template repos diverge from documented patterns
