commit-notation

A format for writing Git commit messages, where Git commits are saved checkpoints describing changes to a codebase. It records both the kind of change and its risk or verification level.

In plain words
What is it for?
Use it when creating, reviewing, or analyzing commits for features, bug fixes, refactoring, documentation, tests, and development-environment changes.
Why use it?
It makes a project's history easier to understand and shows whether a change was checked, safe, risky, or unfinished.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-notation 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 yesterday.

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 — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commit Notation

Source of truth: QuaticoCommitNotation (GitHub) SYNC REQUIRED: Changes here MUST stay consistent with the canonical repo. Changes incomplete without sync.

Quatico uses Arlo's Commit Notation v1 with extensions (T, E).

Quick Reference

Risk Level Format Example
Known Safe x r Extract method getData
Validated X R: Extract method getData
Risky X!! R!! Rename across files
Broken X** F** WIP: new feature

Intentions

Core

Letter Name Use When
F Feature Adding or changing behavior
B Bugfix Fixing broken behavior
R Refactoring Changing implementation, not behavior
D Documentation Non-code documentation changes

Extensions

Letter Name Use When
T Test-only Alter tests without altering functionality
E Environment Dev setup, tooling, non-code changes
WIP Unknown Mixed changes, just checking in

Risk Level Guidelines

Known Safe (lowercase): Provable correctness - tool-verified refactoring, type-checked renames. Validated (UPPERCASE): Test-verified - ran tests, all pass. Risky (XX!!): Attempted but not fully verified. Broken (XX)**: WIP, may not compile, no verification.

Commit Message Format

X: Summary in active voice

TICKET-123

Rules:

  • Separator: : or nothing (e.g., F: Add feature or F Add feature)
  • Voice: Active ("Add feature") not progressive ("Adding feature")
  • Length: Subject < 75 chars
  • Ticket: Last line, blank line before, NO # prefix (git treats # as comment)

Writing Commit Messages

  1. Determine intention: F, B, R, D, T, E, or *
  2. Assess risk level: How verified is this change?
  3. Find ticket number: See below
  4. Format: [prefix] Summary with ticket on last line

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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-notation is a skill published in the GitHub repository quatico-solutions/agent-skills (2 stars, last pushed 7d ago), licensed MIT. It adds 73 tokens to every session and 1,024 once invoked, about $0.0004 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.
