# Babysit PR Watch one PR through CI, auto-fix high-confidence failures, and leave a paper-trail reply on every active review thread and automated review-body comment. Threads stay open for human resolution — this skill only posts replies, it never resolves. This skill is self-contained: it does not invoke other skills. It works in Claude Code and Codex — no subagents, no `Skill` tool calls, no `!` command interpolation, no `$CLAUDE_PLUGIN_ROOT`. ## Inputs Parse an optional PR number or URL from the invocation arguments if the host exposes them; otherwise read the user's request text. Parse in **this priority order** and stop at the first match — do not fall back to a generic "first integer in prose" regex, which would grab unrelated numbers (issue refs, quoted counts, etc.): 1. **Full PR URL** — if `$ARGUMENTS` or the user's text contains `https?://github\.com/[^/\s]+/[^/\s]+/pull/\d+`, capture the URL and pass it to `gh pr checkout` as-is. 2. **Explicit PR token** — match `(?:PR|pr|pull request)\s*#?(\d+)` or a bare `#(\d+)` in the user's text. Capture the numeric group. 3. **Bare numeric argument** — only when the entire `$ARGUMENTS` string is a positive integer (no surrounding prose). 4. **None of the above** — operate on the PR for the current branch (existing Step 2 behavior). When a match is found, the checkout happens in Preflight before Step 2. This skill always runs exactly one pass. It never waits or repeats internally. For recurring execution, wrap the call
