pr-babysit

PR Babysit

Automate the post-PR feedback loop. Polls for new review comments, fixes them, checks CI, resolves merge conflicts, pushes, and repeats until the PR is clean or max rounds are exhausted.

/pr-babysit [--interval 3m] [--max-rounds 5]

Loop:
  1. Fetch PR comments & reviews + CI status + mergeable status (parallel)
  2. Filter for unresolved/new comments since last check, split by human vs bot
  3. Human comments → trade-off assessment + user decision gate (AskUserQuestion or worksheet)
  4. Fix all actionable comments per gate decisions (bot: auto; human: per decision), run quick gates once
  5. Reply to question comments (bot: auto; human: only approved reply, in parallel)
  6. If CI failing → read logs, fix failures
  7. If conflicts → rebase/merge main and resolve conflicts
  8. If changes were made → commit & push, refresh the PR explainer, reset idle counter
  9. If nothing left to fix AND CI green AND no conflicts AND no undecided human comments → final explainer refresh, then [READY TO MERGE]
 10. Otherwise → wait interval, repeat

Prerequisites

The gh CLI must be authenticated with repo scope. The jq command must be available.

Phase 0: Setup

0a. Detect Current PR and Repo Info

Fetch PR data and repo info in parallel:

CURRENT_BRANCH=$(git rev-parse --abbrev-ref HEAD)

# Parallel: PR info + repo info
PR_JSON=$(gh pr view --json number,url,baseRefName,mergeable,mergeStateStatus,createdAt)
REPO_INFO=$(gh repo view --json owner,name)

If no PR exists for the current branch, stop and tell the user to create one first (suggest /make-pr or /pr-make).

Extract:

PR_NUMBER=$(echo "$PR_JSON" | jq -r '.number')
PR_URL=$(echo "$PR_JSON" | jq -r '.url')
BASE_BRANCH=$(echo "$PR_JSON" | jq -r '.baseRefName')
PR_CREATED_AT=$(echo "$PR_JSON" | jq -r '.createdAt')
OWNER=$(echo "$REPO_INFO" | jq -r '.owner.login')
REPO=$(echo "$REPO_INFO" | jq -r '.name')
