Pr Watch

PR Watch

Overview

Poll GitHub PR review status. Auto-fix review comments (Critical/Major/Minor by default) using pr-review-dev. Exit when PR reaches a terminal state: approved, changes_requested_fixed (all blocking issues resolved), timeout, or capped (max fix cycles reached).

Announce at start: "I'm using the pr-watch skill to monitor review state on PR #{pr_number}."

Implements: the pr-watch polling contract

Quick Start

/pr-watch 123 org/repo
/pr-watch 123 org/repo --timeout-hours 48
/pr-watch 123 org/repo --max-review-cycles 5
/pr-watch 123 org/repo --fix-nits
/pr-watch 123 org/repo --no-auto-fix

Poll Loop

1. Fetch PR review state via gh pr view {pr_number} --repo {repo} --json reviews,reviewDecision
2. If reviewDecision == APPROVED: exit with status: approved
3. If reviewDecision == CHANGES_REQUESTED and auto_fix=true and cycles remaining:
   • Dispatch pr-review-dev agent with review comments
   • Increment fix cycle count
   • Wait for CI (delegate to ci-watch if needed), then re-request review
4. If fix cycles exhausted: exit with status: capped
5. If elapsed > timeout_hours: exit with status: timeout
6. If all blocking issues resolved but no explicit approval: exit with status: changes_requested_fixed

Fix Dispatch Contract

Task(
  subagent_type="general-purpose",
  description="pr-watch: fix review comments for PR #{pr_number} (cycle {N})",
  prompt="Invoke: Skill(skill=\"onex:pr_review\", args=\"{pr_number}\")

    Review comments:
    {review_comments}

    Fix all Critical, Major, and Minor issues.{nit_instruction}
    Push fixes to branch: {branch_name}

    Report: issues fixed, files changed, any issues skipped."
)

Skill Result Output

Write ModelSkillResult to $ONEX_STATE_DIR/skill-results/{context_id}/pr-watch.json on exit.

{
  "skill": "pr-watch",
  "status": "approved",
  "pr_number": 123,
  "repo": "org/repo",
  "fix_cycles_used": 2,
  "elapsed_hours": 3.5,
  "context_id": "{context_id}"
}

Status values: approved | changes_requested_fixed | timeout | capped | error
