A guide for writing Git commit messages using Conventional Commits, a standard format that labels changes such as fixes, features, tests, and documentation.

In plain words
What is it for?
Use it to turn a change summary or code diff into a correctly formatted commit message.
Why use it?
It makes commit history easier to understand and helps record breaking changes consistently.

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

conventional-commits 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Conventional Commits

Turn a description of a code change into a commit message that follows the Conventional Commits standard.

When to use

Activate when the user asks for a commit message, or hands you a change summary or diff and wants it phrased for git.

Format

<type>(<optional scope>): <short summary>

<optional body>

<optional footer>
  • type — one of feat, fix, docs, refactor, test, perf, build, ci, chore.
  • scope — the area touched, e.g. (api), (auth). Optional.
  • summary — imperative mood, lowercase, no trailing period, 72 characters or fewer.
  • body — what changed and why, wrapped near 72 characters. Optional.
  • footerBREAKING CHANGE: ... and issue refs like Closes #123. Optional.

Steps

  1. Choose the single type that best fits the change. If it does more than one thing, suggest splitting the commit.
  2. Add a scope only when it clarifies where the change lives.
  3. Write the summary in the imperative ("add", not "added" or "adds").
  4. Add a body only when the why is not obvious from the summary.
  5. Record breaking changes in the footer with BREAKING CHANGE: and a short migration hint.

Examples

Input: "added pagination to the users list endpoint"

feat(api): add pagination to the users list endpoint

Input: "fixed a crash when the config file is missing; now we fall back to defaults"

fix(config): fall back to defaults when the config file is missing

A missing config previously raised at startup. Loading now logs a warning
and uses the built-in defaults instead.

Input: "stopped reading the AWS_REGION env var; region now comes from config"

refactor(config): drop the AWS_REGION env var in favor of a region field

BREAKING CHANGE: AWS_REGION is no longer read. Set `region:` in your model
config instead.

Edge cases

  • Reverting a commit — use revert: <original summary> and put the reverted hash in the body.
  • Several unrelated changes — recommend separate commits rather than one mega-commit.
  • No obvious type — ask what the change is meant to accomplish before guessing.

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.

conventional-commits is a skill published in the GitHub repository strands-compose/sdk-python (6 stars, last pushed 17d ago), licensed Apache-2.0. It adds 43 tokens to every session and 584 once invoked, about $0.0002 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.

Use when a task file exists in .hyperflow/tasks/ and workers need dispatching. Fans out parallel workers under per-batch Reviewers, runs a final integration review, and commits per sub-task. Endpoint of the auto-chain — no auto-deploy. Trigger with /hyperflow:dispatch, "run the plan", "execute the task", "build it"…
