PR Automate

Background PR maintenance, feedback relay, and continuous review. Runs alongside the main agent as a quality gate.

When to use

Spawn this skill as a background subagent after either:

• A new PR is created (gh pr create completes), or
• A push lands on a branch with an open PR (git push completes)

The main agent invokes it via the Agent tool with run_in_background: true so it can work in parallel without blocking.

Token efficiency

Steps 0, 2, 3, 4, 6 and 7 are mechanical: run each as a weak-general-purpose subagent with model: sonnet. Steps 1 and 5 stay in this agent's context, because judging a diff and deciding whether a finding is right are the parts worth paying for.
