auto-commit

A set of guidelines for making small, consistent Git commits while changing code.

In plain words
What is it for?
Use it when committing work incrementally, choosing commit types, or writing commit messages.
Why use it?
It helps keep the project history understandable by grouping each logical change separately and explaining its purpose when needed.

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

auto-commit 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 3d 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.

What it actually says

Git Commit Guidelines

When making changes to code, commit your changes incrementally as you work.

Commit Format

<type>: <subject>

<body>

Commit Types

  • feat: New feature or functionality
  • fix: Bug fix
  • chore: Maintenance tasks, dependency updates, configuration changes
  • docs: Documentation only changes
  • style: Code style/formatting changes (no functional changes)
  • refactor: Code restructuring without changing functionality
  • test: Adding or modifying tests
  • perf: Performance improvements

Subject Line Rules

  • Maximum 90 characters
  • Start with lowercase
  • No period at the end
  • Use imperative mood ("add" not "adds" or "added")

Body Rules

  • Separate from subject with blank line
  • Wrap at 72 characters
  • Explain what and why, not how
  • Only include when the change requires context

Commit Frequency

  • Commit after each logical unit of change
  • Each commit should represent one coherent change
  • Don't bundle unrelated changes

Examples

Good Examples

feat: add user authentication middleware

Implements JWT-based authentication for API routes.
Includes token validation and refresh logic.
fix: resolve null pointer in user lookup
chore: update dependencies to latest versions

Bad Examples

feat: added new feature to the application that allows users to authenticate using JWT tokens and also fixed some bugs and updated dependencies
fix: Fixed bug.

Key Principles

  • Be concise but descriptive
  • One commit = one logical change
  • Commit message should make sense without looking at the code
  • Skip the body if the subject line is self-explanatory
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.

auto-commit is a skill published in the GitHub repository jahands/prompts (19 stars, last pushed 7mo ago), licensed MIT. It adds 23 tokens to every session and 399 once invoked, about $0.0001 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 2026-08-30.
