Change briefings from commits and PRs
Have the model summarise what actually changed in a build — from commits, pull requests and tickets — in terms of behaviour a tester can check, not code.
How it works
Release notes describe intent; the diff describes what happened. The model is given the commits, pull-request descriptions and linked tickets between two versions and asked for a briefing aimed at testing: which user-facing behaviours changed, which areas were touched without a ticket explaining why, which changes are large or spread across many files, and which pull requests merged with little review discussion. Asking it to flag mismatches — a ticket that says "copy change" attached to a diff that touches validation logic — is often the most useful part. The briefing becomes the starting list for regression and exploratory work on the build.
When to use it
When a build lands for testing and the release notes are thin; on teams where testers aren't in every code review; before a release, to check nothing went in that nobody mentioned; and when picking up a branch someone else worked on.
Limitations
Commit messages and pull-request descriptions are often vague or wrong, and the model can only summarise what it is shown; reading the actual diff helps but large diffs exceed what fits. It describes changes, not their consequences — a one-line config change can have the widest impact of anything in the release and look trivial in the summary. Generated or vendored code inflates the size of changes that don't matter.
Watch for
A pull request titled “refactor” that also changes how prices round is briefed as no behaviour change, because the model only read its description, and nobody tests it. Have the briefing say for each change whether it read the diff, and treat description-only items as unchecked.
What you still own
Deciding which changes carry risk, and looking at the diff yourself for anything the briefing marks as small but sensitive.
