What it helps you do

Use this skill because it turns “what changed?” and commit-prep work into a consistent reviewable command.

Skills load their full instructions only when used, which keeps normal session context smaller.

A reusable `SKILL.md` gives teams a versioned workflow instead of repeated ad hoc prompts.

Best fit users

developers preparing commits, PR descriptions, release notes, or handoff summaries.

Teams standardizing AI-assisted delivery across multiple repositories.

Builders who want Claude to apply consistent procedures without repasting instructions.

What to know first

A skill directory such as `.claude/skills/<skill-name>/SKILL.md` or `~/.claude/skills/<skill-name>/SKILL.md`.

A concise frontmatter description so Claude can decide when to load the skill.
