What it does

Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject ≤50 chars, body only when "why" isn't obvious. Use when user says "write a commit", "commit message", "generate commit", "/commit", or invokes /caveman-commit. Auto-triggers when staging changes.

Installed, it changes the agent in these ways.

What this skill changes about the agent is not written down here yet. The listing was collected from its source, and the description is in its own SKILL.md.

Workflow

Runs a procedure end to end.

The skill itself

This is the whole product. A skill is instructions the model reads, so there is nothing behind the listing you cannot see first — the front matter loads with every session, and the body below it loads when the skill triggers.

10Write commit messages terse and exact. Conventional Commits format. No fluff. Why over what.

12## Rules
13
14**Subject line:**
15- <type>(<scope>): <imperative summary><scope> optional
16- Types: feat, fix, refactor, perf, docs, test, chore, build, ci, style, revert
17- Imperative mood: "add", "fix", "remove" — not "added", "adds", "adding"
18- ≤50 chars when possible, hard cap 72
19- No trailing period
20- Match project convention for capitalization after the colon
21
22**Body (only if needed):**
23- Skip entirely when subject is self-explanatory
24- Add body only for: non-obvious *why*, breaking changes, migration notes, linked issues
25- Wrap at 72 chars
26- Bullets - not *
27- Reference issues/PRs at end: Closes #42, Refs #17
28
29**What NEVER goes in:**
30- "This commit does X", "I", "we", "now", "currently" — the diff says what
31- "As requested by..." — use Co-authored-by trailer
32- "Generated with Claude Code" or any AI attribution — unless the user's own rule requires an Assisted-by/AI-attribution trailer, then add it as a trailer
33- Emoji (unless project convention requires)
34- Restating the file name when scope already says it
35
36## Examples
37
38Diff: new endpoint for user profile with body explaining the why
39- ❌ "feat: add a new endpoint to get user profile information from the database"
40-
41 ```
42 feat(api): add GET /users/:id/profile
43
44 Mobile client needs profile data without the full user payload
45 to reduce LTE bandwidth on cold-launch screens.
46
47 Closes #128
48 ```
49
50Diff: breaking API change
51-
52 ```
53 feat(api)!: rename /v1/orders to /v1/checkout
54
55 BREAKING CHANGE: clients on /v1/orders must migrate to /v1/checkout
56 before 2026-06-01. Old route returns 410 after that date.
57 ```
58
59## Auto-Clarity
60
61Always include body for: breaking changes, security fixes, data migrations, anything reverting a prior commit. Never compress these into subject-only — future debuggers need the context.
62
63## Boundaries
64
65Only generates the commit message. Does not run git commit, does not stage files, does not amend. Output the message as a code block ready to paste. "stop caveman-commit" or "normal mode": revert to verbose commit style.

Why you can read it

Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.

What it costs in context

Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.

≈100
always loaded
The name and description, so the model knows the skill exists and when to reach for it.
850
on trigger
The instruction body and 1 supporting file, read only when the skill fires.
0.47%
of a 200k window
Ten skills this size would take about 5% of the window before you open a file.
050k100k150k200k context window

950 tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Small enough to keep loaded permanently without thinking about it.

Servers bill, skills cost

A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.

Before and after

The same question, put to the same model twice: once as it comes, and once with these instructions loaded.

The procedure it runs

The procedure has not been published here. It is in the skill’s own SKILL.md, which its author has not sent to the marketplace yet.

Prose, not code

These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.

Servers it uses

None. This skill calls no MCP servers at all.

Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.

It writes no files and reaches no network. All it changes is how the model reasons and writes.

What it asks for
Writes filesno
Network accessno

Read from the allowed-tools line of this skill’s own SKILL.md. A skill grants no permissions of its own — it can only ask for tools your client already has.

What it will not do

Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.

What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.

What is in the bundle

2 files, 3.8 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

  • README.md1.2 kB
  • SKILL.md2.6 kB
What is not in it

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 2 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.

Install

Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

LicenceMIT — the author’s, unchanged by this purchase
Paid throughStripe, once, on the card you add at the checkout
Keeps workingfor good — the files are yours once they are on disk
Updatesevery update its author ships, delivered through this account

You can read the whole bundle before paying — the SKILL.md above is the product, not a preview of it. What the money buys is the delivery: the folder packaged and handed to your machine by key, every update its author ships, and our support if it does not do what this listing says. The terms of use are MIT, set by the author and unchanged by buying it here.

Payment runs through Stripe, on a page like this one rather than a redirect. Once there is an account it joins the same mcprush invoice as everything else you run, so there is never a second card to enter.

Which clients pick it up on their own

A skill is a folder of text. A client with a skills folder reads it without being told; everywhere else the same text works, it is just handed to the model rather than found.

Versions

Its author publishes no version number, so there is nothing here to pin to: what you install is the folder as it stands today. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.

Pinning

Nothing to pin to: this skill carries no version number of its own. What you install is what the folder holds on the day you install it.

Reviews

no reviews yet · no installs yet

Nobody has reviewed this skill yet. The rating is the mean of the reviews written here, so there is none until somebody writes the first.

Who can post

Only accounts that have had the skill installed for fourteen days, so a review is written after living with it rather than after reading it. Publishers may reply once.
