Investigate mismatches before proceeding. + +## 2. Open or update the PR + +- Reuse an existing PR for the branch. Target the correct base and keep the PR limited to the task. +- Describe what changed, why, actual verification results, and any risks, migration requirements, or limitations. Never claim unrun tests passed. +- Open ready for review only after local verification is complete. If work needs an earlier draft, complete verification before marking it ready. +- With `gh`, use a body file for multiline PR descriptions and comments so actual newlines and literal text survive shell quoting. + +## 3.

Verify actual startup through live GitHub review activity or the review service's task state. If the opening review does not start, check access, configuration, and failure messages. After confirming no review is running or queued, request `@codex review` once if appropriate; repeated comments do not repair missing access or quota. + +Wait for the full exhaustive review, including review summaries, inline comments, and review threads. An early summary, completed check, or thumbs-up alone is insufficient while further findings may still arrive. Re-read comments and threads after completion. If the available evidence cannot establish full completion, keep the review gate pending and report the uncertainty; silence or an arbitrary quiet period is not proof. + +Associate all review evidence with the exact PR head SHA. Prefer review or task metadata that identifies the reviewed commit. Record the review/task identifiers, URLs, and completion evidence. When a comment or reaction lacks commit metadata, seek corroborating task evidence instead of assigning it to the current head from its timestamp alone. A clean review of an older commit does not approve a newer head. + +Use `t3code babysit inspect --pr ` for deterministic evidence gathering. A submitted review on the current commit proves submission, not exhaustive completion. The helper deliberately leaves readiness unknown until corroborated completion evidence is recorded. After checking the review service's completed task and reviewed commit, run `t3code babysit record --pr --review-evidence --head --url --note `. Never record that evidence from silence, an early summary, or an unbound thumbs-up. + +## 4. Repair and re-review + +- Inspect CI logs, review summaries, inline comments, and unresolved threads.

If no review of the new head is already running or queued, comment `@codex review` once.

Repeat until the final head has a completed review and no actionable blocking findings. +- Do not resolve a thread merely to clear a gate. Record how the finding was fixed or refuted, including the relevant commit or evidence, and respect repository rules about who may resolve it. + +If Codex is rate-limited or unavailable, keep the PR unmerged and report the blocker. Rate limits are not approval. Do not enable paid credits, bypass review, or silently substitute another reviewer.

Bind every review request to its commit with `record --pr --review-request --head --url `. Check saved requests before posting another one. Use `decide --pr --finding --decision fixed|refuted --evidence ` for assessed findings; a new or edited comment reopens the finding.

Determine that ID from the environment or inspect an explicitly identified thread; never guess between similarly titled conversations. A settled thread requires explicit continuing authorization before adding `--wake-settled`. State lives outside tracked source in `~/.babysit/v1/`; `status --pr ` exposes the observations, pending events, and delivery errors. The helper never merges or requests a review itself. Read [helper.md](references/helper.md) when configuring fallback schedules, resuming an event, or interpreting unknown evidence. + +**Inside T3:** handle existing findings, link the PR, call the available `watch_pull_request` tool, and end the turn. Use the native watch first when its documented contract covers the required events. T3 owns future wakes. Do not also start a scheduled tick or an agent-owned polling process. On a wake, run a fresh `inspect`, act within the saved authorization, record evidence, and register/reconfirm the native watch before yielding again if the workflow remains pending. A native wake is news, not approval to merge. If native monitoring ends because the PR cannot be read, report that blocker and the actual monitoring status. + +**Fallback:** when native watch is unavailable, use the helper's `schedule-command --pr ` to generate one OS-owned `tick` task. Inspect and run the generated registration command, save its identity/cancellation instruction, and verify the first successful tick observed the correct PR/head before calling monitoring active. A tick performs API reads without an LLM; it sends a wake only for a material change. It queues delivery to the original T3 conversation and does not launch T3 when closed. Stop any old watcher before changing mechanisms. + +**Without durable delivery:** use `wait --pr --timeout ` within the active session. It makes no model call while sleeping. Disclose that this wait ends with the session; it is not durable monitoring. + +**On helper-delivered wakes:** run `inspect`, handle the event or record a concrete blocker, then `ack --pr --event --note `. Delivery acceptance is not acknowledgment of handled work. Interrupted work stays unacknowledged in `status` and later wakes; deliberate recovery uses `wake --pr --redeliver `. Ambiguous delivery retries reuse the persisted text and event key. Rejected sends require diagnosis and explicit redelivery. Never start a second repair loop for the same PR. + +Keep unchanged observations silent and send brief updates for material changes. Unknown or incomplete evidence keeps the relevant gate pending. If the helper cannot express a gate, report the missing evidence rather than substituting an ad hoc parser. + +## 6. Merge only after final verification + +Immediately before merging, re-read the live PR state and verify every gate: + +- The head is the exact commit tested and reviewed. +- Required checks have passed for the applicable commit or merge candidate. Missing, skipped, or cancelled checks are not automatically passing evidence; establish whether repository policy requires them and whether the applicable checks actually ran. +- Codex has completed the full review of the final head, and comments and threads have been rechecked after completion. +- No actionable blocking findings remain. +- Required human approvals and repository rules are satisfied. +- The PR is mergeable, and no new commits, comments, or review activity invalidate readiness. + +If the head changes, rerun affected checks and obtain Codex review of the new head. If the base changes, reassess integration and refresh checks as required by repository policy. Resolve in-scope conflicts, then verify and review the resulting head. Re-read the state after any readiness-changing event. + +Use the repository's merge method, defaulting to squash when no convention exists. Bind the merge to the verified head SHA where supported. Never use administrator bypass. Do not enable auto-merge before review gates are satisfied when branch protection does not enforce those gates. Continue monitoring while auto-merge or a merge queue is pending; enabling either is not completion. + +## 7. Prove completion + +Verify through GitHub that the PR is actually merged. Report: + +- PR URL. +- Verified pre-merge head SHA and resulting merge commit SHA. +- Local test results and final CI results, including material checks not run. +- Final Codex review outcome and any required human approval outcome. +- Remaining non-blocking limitations, if any. + +If GitHub shows the PR closed without merge, report that outcome accurately. A blocked handoff must name the unsatisfied gate, relevant evidence, the decision or external change needed, and the actual monitoring status. + +Stop any watcher and clean up only the task's branch or worktree, preserving unrelated work. Do not claim deployment or production verification unless separately requested and actually performed. + +Run `t3code babysit stop --pr --reason merged|closed|cancelled` when the workflow ends.
