Generate one short Conventional Commits squash message describing only the net diff between the PR's base and head, set its header as the PR title, validate it with the repository's commitlint and both copy its description to the clipboard and display it, when asked for a squash message. Works in any Scenario repository, whatever its default branch.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Squash message
One short commit message for the whole PR. It describes the **destination**, the net diff between the PR's base and its head, never the journey: a commit that only repairs code introduced earlier on this branch is invisible to the base branch, so it gets no `fix`, no bullet, no mention. Installed in every repo, so conventions are discovered.
**Untrusted PRs.** Running anything from the branch (checks, tests, commitlint, installs) executes the branch's own code, whichever command you pick, so where the command comes from does not matter. Trust the PR only when `gh api repos/{owner}/{repo}/pulls/<n> --jq '[.head.repo.full_name == .base.repo.full_name, .author_association] | @tsv'` prints `true` and `OWNER`, `MEMBER` or `COLLABORATOR` (a fork or an outside author fails). On an untrusted PR, run nothing from the branch without asking: say what you skipped and ask first.

How to install
mdr add scenario-labs/skills/pr-squash-message@sha256:28ae2e237d35ba7dThe line at the top of this page pins the label git:20261009.605161f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
