Thanks for looping me in and for the prod on consistency. I agree that writing
a clear commit message or pull request summary is often harder than the code
change itself.

With AUTOSEL we’ve seen that AI can help when it’s grounded: recent agentic RAG
approaches let us draft summaries from the actual commits, tags, diffstats, and
paths rather than free-form guesses. We still treat the result as a bot-edited
draft, not an authority.

Looping in Konstantin who looked at adding extensions such as these to b4 - we
should definitely look at adding more AI tools to support maintainer workflows
with good guardrails (including sourcing every claim from the input data,
failing closed on low confidence, ...).

Some more b4 ai ideas:

- b4 ai summarize <range|branch>: Draft a maintainer editable summary
   (headline, grouped highlights, notable fixes/reverts, stats), with links to
   source commits.

- b4 ai cover <series>: Generate a first-pass cover letter for a series or
   topic branch, preserving style knobs (indentation, bullets, length).

- b4 ai risks <range>: Surface cross-subsystem touches, large churn, and code
   with prior regression history.

- b4 ai validate <range>: Check that summary claims are supported by
   commits/tags. Flag low-confidence sections.

- b4 ai style --indent=2 --max-lines=...: Apply consistent formatting to the
   generated text without changing content.
