Babysit

Babysit a pull request

This skill is a thin client adapter over the persistent cenci babysit supervisor. The supervisor owns polling and retry state outside the repository, so it keeps running after the invoking agent session exits. It launches an agent only when CI fails, actionable review feedback arrives, or a retry cap needs human input.

Read the shared shell-rules skill before invoking the CLI.

Invocation

Parse the first argument as a PR number, stripping a leading #. Reject missing or non-numeric PRs. Parse the optional second argument as the interval.

Read project-core, resolve neutral configuration, and use the resulting config.

Resolve the interval consistently with implement's auto-launched hand-off (implement Phase 9 arms cenci babysit the same way), so a manual and an auto-armed supervisor agree on cadence: explicit interval arg → the babysitInterval config field → 15m default. When no second argument is given, resolve .cenci/config.json's optional babysitInterval via the shared hooks/scripts/resolve-babysit-interval.sh resolver — the single source of truth for this field. Run it under Claude as:

sh "${CLAUDE_PLUGIN_ROOT}/hooks/scripts/resolve-babysit-interval.sh"

(under Codex, ${PLUGIN_ROOT} replaces ${CLAUDE_PLUGIN_ROOT}); pass the affected project's slug for a monorepo, no slug for a single-repo top-level lookup. Non-empty output → use it as <interval>; empty output (field unset, or no config file) → omit --interval entirely and let cenci babysit apply its built-in 15m default. An explicit second argument always wins over the config.

Detect the current client and run exactly one of the three (dropping --interval <interval> when the interval was neither passed as an argument nor resolved from config):

cenci babysit <pr> --agent claude --interval <interval>

cenci babysit <pr> --agent codex --interval <interval>

cenci babysit <pr> --agent opencode --interval <interval>

Use --once only when the user explicitly requests one tick. To stop a supervisor:

cenci babysit stop <pr>

Report the command's result. Do not reproduce the polling pipeline in the agent session, arm Claude /loop, create a Codex goal, or maintain ${TMPDIR:-/tmp}/cenci state.

Safety guarantees

The supervisor never force-pushes. It launches the selected client through cenci run for CI repair or review handling, preserving those workflows' approval gates. Launched repair agents confirm a fix against the project's local gate (docs/health-gates.md, exit-0-is-healthy) before pushing, so a broken fix is caught locally instead of via a CI round-trip. After three failed repair launches it pauses and opens a visible babysit window for human direction.

On a merged PR, each closing issue's In Review label swaps to Implemented first, exactly as before. The supervisor then reconciles split-parent completion at merge time from the live native GitHub parent/sub-issue graph — never from a plan-time isLastChild value. For each closed issue's native parent, once every native subIssues node on that parent reads CLOSED, the parent is eligible to close, but only if its comment thread carries no live (non-blockquoted) parent-gap-report marker (docs/comment-attribution.md): no marker closes and relabels the parent Implemented; a live marker leaves the parent untouched and reports a distinguishable "held by a recorded acceptance-criteria gap report" outcome for human triage instead. An unreadable, empty, or truncated sub-issue graph, or an unreadable or truncated comment read, fails closed with no parent mutation. An already-closed parent is an idempotent no-op. A stale gap report holds the parent indefinitely until a human resolves it — by editing or deleting the comment, or by closing the parent manually; babysit only detects a recorded gap report, it never supersedes or re-audits one. A PR closed without merging leaves labels unchanged.
