# PR Finisher Drive an open PR for the current branch to a merge-ready state from a **GitHub Copilot cloud agent**. **Do not merge.** When everything you can act on is done, report ready-for-human-merge and stop. ## Execution context This skill runs inside a GitHub Copilot cloud agent, not on a developer's machine. - **The agent's pushes do not trigger CI.** Workflows on the PR will not re-run after the agent commits. Any existing `statusCheckRollup` reflects an earlier HEAD and goes stale the moment the agent pushes. - **Commit and push on every iteration that changes files.** Changes that are not pushed are not available to the user. - **Local `make` targets are the agent's authoritative correctness signal** before push. CI is observational only. - **Re-running CI is a hand-off to a human** (close/reopen the PR, `workflow_dispatch`, or a push from a maintainer). The agent must surface this in its summary. - **No watch / no sleep loops.** The agent has no async wait state; one pass + summary + stop. ## Three merge-ready conditions A PR is merge-ready when **all three** are satisfied. Work them **concurrently**. | Condition | Definition | Agent's signal | |---|---|---| | **Reviews** | Every unresolved in-scope review thread is addressed on its merits, replied to, and resolved, including GitHub Actions bot threads/comments (`github-actions[bot]`). Code changes alone do not satisfy this. | `copilot-review` skill + GraphQL `reviewThreads` | | **Checks** | Local `make fmt`...
