What it does
Caveman Commit is an agent skill from vishiri/fantasia-archive. 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.
Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `README.md`).
It sits in Development, covering Commit messages. The repository describes itself as: A world-builder's best friend! The licence is GPL-3.0.
When your agent uses it
- User says write a commit
- Generate commit
- Invokes /caveman-commit
- Staging changes
Example prompts
- “t obvious. Use when user says”
- “commit message”
- “generate commit”
- “/caveman-commit”
What it can do on your machine
Read from SKILL.md and the folder at commit a3a68e1. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Caveman Commit loads about 642 tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 249 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- caveman-commit
- description
- 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.
Write commit messages terse and exact. Conventional Commits format. No fluff. Why over what.
Rules
Subject line:
<type>(<scope>): <imperative summary>—<scope>optional- Types:
feat,fix,refactor,perf,docs,test,chore,build,ci,style,revert - Imperative mood: "add", "fix", "remove" — not "added", "adds", "adding"
- ≤50 chars when possible, hard cap 72
- No trailing period
- Match project convention for capitalization after the colon
Body (only if needed):
- Skip entirely when subject is self-explanatory
- Add body only for: non-obvious why, breaking changes, migration notes, linked issues
- Wrap at 72 chars
- Bullets
-not* - Reference issues/PRs at end:
Closes #42,Refs #17
What NEVER goes in:
- "This commit does X", "I", "we", "now", "currently" — the diff says what
- "As requested by..." — use Co-authored-by trailer
- "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 - Emoji (unless project convention requires)
- Restating the file name when scope already says it
Examples
Diff: new endpoint for user profile with body explaining the why
- ❌ "feat: add a new endpoint to get user profile information from the database"
- ✅
feat(api): add GET /users/:id/profile Mobile client needs profile data without the full user payload to reduce LTE bandwidth on cold-launch screens. Closes #128
Diff: breaking API change
- ✅
feat(api)!: rename /v1/orders to /v1/checkout BREAKING CHANGE: clients on /v1/orders must migrate to /v1/checkout before 2026-06-01. Old route returns 410 after that date.
Auto-Clarity
Always 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.
Boundaries
Only 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.
