+# GitHub CLI / API Notes For `babysit-pr`
+
+## Primary commands used
+
+### PR metadata
+
+- `gh pr view --json number,url,state,mergedAt,closedAt,headRefName,headRefOid,headRepository,headRepositoryOwner`
+
+Used to resolve PR number, URL, branch, head SHA, and closed/merged state.
+
+### PR checks summary
+
+- `gh pr checks --json name,state,bucket,link,workflow,event,startedAt,completedAt`
+
+Used to compute pending/failed/passed counts and whether the current CI round is terminal.
+
+### Workflow runs for head SHA
+
+- `gh api repos/{owner}/{repo}/actions/runs -X GET -f head_sha=<sha> -f per_page=100`
+
+Used to discover failed workflow runs and rerunnable run IDs.
+
+### Failed log inspection
+
+- `gh run view <run-id> --json jobs,name,workflowName,conclusion,status,url,headSha`
+- `gh api repos/{owner}/{repo}/actions/runs/{run_id}/jobs -X GET -f per_page=100`
+- `gh api repos/{owner}/{repo}/actions/jobs/{job_id}/logs > /tmp/codex-gh-job-{job_id}-logs.zip`
+- `gh run view <run-id> --log-failed`
+
+Used by Codex to classify branch-related vs flaky/unrelated failures. Prefer the direct job log endpoint as soon as a job has failed because `gh run view --log-failed` may not produce failed-job logs until the overall workflow run completes.
+
+### Retry failed jobs only
+
+- `gh run rerun <run-id> --failed`
+
+Reruns only failed jobs (and dependencies) for a workflow run.
+
+## Review-related endpoints
+
+- Issue comments on PR:
+  - `gh api repos/{owner}/{repo}/issues/<pr_number>/comments?per_page=100`
+- Inline PR review comments:
+  - `gh api repos/{owner}/{repo}/pulls/<pr_number>/comments?per_page=100`
+- Review submissions:
+  - `gh api repos/{owner}/{repo}/pulls/<pr_number>/reviews?per_page=100`
