Coordinate reviewer changes before they create drift
A reviewer change can signal a handoff or a blocker. Find time to align before the pull request starts circulating without an owner.
Trigger
GitHub Pull Request Reviewers Changed
Triggers when the list of requested reviewers (users or teams) for a pull request changes — for example when a reviewer is added, removed, or re-requested. The payload includes the full current reviewer list (users and teams with details), which reviewers were added, which were removed, and the previous reviewer list for reference.
Action
Check calendar availability
Retrieves free/busy availability for a specified calendar to aid scheduling without revealing event details; requires an existing, accessible calendar, noting that data granularity can vary.
Why this helps
Reviewer changes can create ambiguity that remains unresolved across comments and notifications.
- Makes reviewer handoffs easier to close.
- Reduces ambiguity around ownership.
- Prevents long comment threads from replacing a short conversation.

- 3Use this instruction: When the requested reviewers on a GitHub pull request change, check Cal availability for a short coordination conversation and report suitable windows.
- 4Choose GitHub Pull Request Reviewers Changed and select a reporting channel.
- 5Test with one real reviewer change.
