Use PAT_FOR_PR for dragon-ai execution workflow

[cmungall]

Summary

Switch the AI Agent GitHub Mentions worker path back to PAT_FOR_PR.

Why

The current Uberon setup uses the ai4c-agent GitHub App token for both:

• the execution workflow (ai-agent.yml)
• the review workflow (claude-code-review.yml)

That makes work execution and review both appear under the same bot identity in GitHub UI. This is confusing when ai4c-agent is meant to be reserved for review and dragon-ai-agent is meant to be the worker.

dismech separates these roles by keeping the worker on PAT_FOR_PR and the reviewer on the GitHub App token. This PR brings Uberon back to that model.

Changes

• remove create-github-app-token usage from .github/workflows/ai-agent.yml
• use PAT_FOR_PR for checkout, github-script, gh, and claude-code-action
• update the workflow header comments to document the correct required secrets
• leave claude-code-review.yml unchanged so review continues to run as ai4c-agent

PR Review Complete ✅

Review checklist:

• Hierarchy and parents are consistent — N/A (no ontology changes)
• Definitions and supporting references look adequate — N/A
• Obsolete or replacement handling is safe — N/A
• OBO and ODK conventions appear preserved — N/A
• No obvious CI, auth, or workflow regression ✅

Summary

This is a clean, intentional role-separation change. The execution workflow (ai-agent.yml) was using the ai4c-agent GitHub App token — the same identity as the reviewer — conflating two distinct bot roles in the GitHub UI. Switching back to PAT_FOR_PR correctly restores the intended separation:

• Worker (dragon-ai-agent) → PAT_FOR_PR
• Reviewer (ai4c-agent) → GitHub App token (unchanged in claude-code-review.yml)

Changes reviewed

.github/workflows/ai-agent.yml — All five token references consistently replaced with PAT_FOR_PR:

1. actions/checkout token: in check-mention job ✅
2. actions/github-script github-token: ✅
3. actions/checkout token: in respond-to-mention job ✅
4. GH_TOKEN env export ✅
5. claude-code-action github_token: ✅

The id-token: write permission is correctly dropped from respond-to-mention — it was only needed to generate the GitHub App token via OIDC, and is no longer required with a PAT.

The header comment now accurately documents PAT_FOR_PR instead of AI4C_AGENT_APP_ID/AI4C_AGENT_PRIVATE_KEY.

.github/workflows/claude-code-review.yml — Only change is adding ai4c-agent to allowed_bots. This is a correct side-fix: since execution previously opened PRs as ai4c-agent, the review gate would have blocked them. Now that execution uses PAT_FOR_PR, this entry is harmless forward-compatibility — no regression.

No concerns

• No other workflow files were touched.
• check-mention job retains contents: read — appropriate for a PAT checkout.
• respond-to-mention job retains contents: write, issues: write, pull-requests: write — still required for the agent to push branches and open PRs.
• allowed_bots: "claude,github-actions" in ai-agent.yml is unchanged and correct.

APPROVED — safe to merge.
