commit-log

A release-writing helper for the Aumovio platform that creates conventional commit messages and structured changelog entries. A changelog is a record of notable software changes.

In plain words
What is it for?
Writing separate frontend and backend commit messages, plus changelog fields describing the type, title, message, and changes.
Why use it?
It converts a plain description of work into consistent text for both version-control history and release notes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

commit-log scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a release-note generator for the Aumovio platform. Every invocation produces two outputs in order — commit message(s) first, changelog entry second. Apply caveman-commit rules throughout. No fluff. Why over what.


Step 1 — Commit message(s)

Apply these rules (inherited from caveman-commit):

  • Format: <type>(<scope>): <imperative summary>
  • Types: feat fix refactor perf docs test chore build ci style revert
  • Subject ≤50 chars preferred, hard cap 72. No trailing period.
  • Body only when the WHY is non-obvious, breaking, or migration-relevant.
  • Wrap body at 72 chars. Bullets - not *.
  • Never: "this commit", "I", "we", AI attribution, emoji, restate file name.

Always produce two separate commit blocks — one for Frontend, one for Backend. Label each block clearly:

### Frontend
<commit message here>

### Backend
<commit message here>

If one side has no changes this session, output a _No changes._ line under that heading instead of omitting the block. Never silently drop a section — both headings must always appear so the output is consistent and copy-paste ready.


Step 2 — Changelog entry fields

Produce a fenced block with exactly these fields — ready to paste into the Version History "New Entry" modal:

Type:          <feat | fix | perf | refactor | security | docs | chore>
Title:         <≤60 chars, title case, no version number>
Message:       <1–2 sentences, present tense, user-facing benefit first>
What Changed:
- <top-level change>
  - <nested sub-detail if needed>
- <top-level change>
...

Rules for changelog fields:

  • Type must match the commit type exactly.
  • Title is the human-readable feature name — not the commit subject.
  • Message is what a non-engineer reading the changelog will understand. Lead with the user-visible benefit, not the implementation detail.
  • What Changed mirrors the commit body bullets but written for an audience that includes non-engineers. Max 8 top-level bullets. Nest sub-bullets with 2-space indent (matches the changelog textarea parser).
  • Always produce one combined changelog entry covering both Frontend and Backend changes together. Users read the changelog as a product release, not a per-repo diff — merge the What Changed bullets from both sides into a single list, grouping FE and BE items under sub-headings only when the lists are long enough to warrant separation (6+ bullets per side). When one side has no changes, simply omit that side's bullets — do not add a "No changes" line.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

commit-log is a skill published in the GitHub repository Jm-Paunlagui/CATHERINE (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 99 tokens to every session and 1,133 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
