[P3] Uninstall the Claude GitHub App (review still queues on every push) #389

Why

Claude Code review is gone from git:

• claude.yml / claude-code-review.yml deleted on main and dev (chore(ci): drop Claude Code GitHub Actions (#359) #381 → Release: dev → main #380)
• GitHub Actions records are state: deleted (ids 226205447, 226204108) and cannot be disabled further
• CLAUDE_CODE_OAUTH_TOKEN is not on the repo ([P3] Delete CLAUDE_CODE_OAUTH_TOKEN after Claude Actions reach main #384)
• Protect Main does not require a Claude check

The Claude GitHub App (https://github.com/apps/claude, app id 1236702) is still installed. It still opens a check suite named Claude (queued) on every push, including dd66793 on main after #380. Permissions include contents: write, workflows: write, pull_requests: write.

That is the leftover review hook. Workflow file deletion does not uninstall the app.

The gh OAuth token cannot list or delete GitHub App installations (403 / 404). This needs a click in the GitHub UI.

How

1. Open Installed GitHub Apps (account) or the repo Installations page while signed in as MehdiZare.
2. Find Claude (Anthropic).
3. Uninstall it, or Configure → remove MehdiZare/fmp-data from the installation.
4. Confirm a new push to main/dev no longer creates a Claude check suite (gh api repos/MehdiZare/fmp-data/commits/<sha>/check-suites --jq '.check_suites[] | select(.app.slug=="claude")' should be empty).

Keep Claude Desktop MCP and CLAUDE.md. Those are not the review app.

Also true, not this issue

Dozens of stale remote branches still contain the old workflow files. A PR opened from those branches would re-introduce claude-code-review.yml in the PR tree. Uninstalling the app is the kill switch even for that. Cleaning the stale branches is optional hygiene.
