| description | Run metareview post-merge learning after a PR or local merge completes; curates reusable review knowledge, records discarded low-value candidates, and appends reviewer calibration. |
Learn Post Merge
Run this after a PR merge or after a local epic lands.
Command
metareview learn --post-merge <pr-number> --base <pre-merge-ref> [--github-pr <number>] [--session-root <path>]
Use --base for the final reviewed diff, --github-pr when the GitHub PR number differs from the merge identifier, and --session-root when the relevant coding session history is in a nonstandard location.
Workflow
- Run the command from the repository root after confirmed merge.
- Inspect the accepted learning log and discard log under
docs/metareview/learning/.
- Keep accepted knowledge only when it would change a future reviewer’s behavior on a similar task.
- Commit the learning artifacts and JSONL knowledge/calibration changes with the merge follow-up work.
GitHub and session history are optional local context. Missing adapters are recorded as unavailable context rather than failing learning.
Metaswarm Contract
In a metaswarm flow:
metareview review task-done <task-id-or-path> runs when a work unit claims done.metareview review epic-ready <epic-id-or-path> runs before an epic is called locally complete.metareview review pr-ready --base <base-ref> runs before PR push or merge readiness.metareview learn --post-merge <pr-number> --base <pre-merge-ref> runs after confirmed PR merge.
Post-merge learning is advisory by default. In strict mode, the caller treats a nonzero learning exit as blocking release cleanup until the run succeeds or is explicitly waived.
