# Update Changelog

## Context

!`git log $(git describe --tags --abbrev=0 2>/dev/null || echo HEAD~20)..HEAD --oneline`

## Instructions

1. Read `CHANGELOG.md` to understand current state and format.

2. If `$ARGUMENTS` is provided, add it as a `- ` entry under `## Unreleased`.

3. If no arguments, analyze commits since last tag (see context) and draft entries as a flat bullet list under `## Unreleased` (no subcategories).

4. Entry format:
   - Flat `- ` bullet list (no `### Added/Changed/Fixed` sections)
   - Imperative mood: "Add" not "Added"
   - Code in backticks: `` `ClassName::method()` ``
   - Under 100 chars per entry
   - Skip non-user-facing commits (`chore:`, CI, internal refactoring)
   - Prefix breaking changes with **BREAKING**

5. Edit `CHANGELOG.md` to add the entries. Present draft before writing if generating from commits.
