What What Changed does

description: Summarize what changed since a git ref (branch, tag, date) argument-hint: (e.g. main, v2.1, HEAD~10, "yesterday")

Summarize what's changed since $ARGUMENTS.

Process

**Resolve the ref.** If $ARGUMENTS looks like a tag/branch/commit, diff against it with `git log ..HEAD`. If it looks like a date ("yesterday", "2 weeks ago", "2025-10-01"), use `git log --since=""`. If it's empty or ambiguous, ask.
**Pull the data:**
- `git log --no-merge
