commit-and-pr-messages

commit-and-pr-messages is a skill for Claude Code, Codex from superplanehq/superplane. It costs 97 tokens per session (1,338 once invoked), scanned A, original, Apache-2.0.

A writing guide for Git commit messages and pull request descriptions. Git records code changes, while a pull request is a proposed change for teammates to review; the guide emphasizes short subjects and explains why a change was made.

In plain words
What is it for?
Use it when creating or editing commit messages, pull request titles, pull request descriptions, or checking whether a description gives reviewers useful context.
Why use it?
It helps future readers understand the purpose of a change instead of having to infer it from the code difference alone. It also keeps project history consistent and easy to scan.

About the project

SuperPlane is an open-source automation system that turns selected software backlog issues into pull requests by coordinating coding agents, source control, testing, review, and approvals. Engineering teams use it to automate routine development work while keeping ambiguous decisions for humans, and the catalogue add-ons support its workflows.

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-and-pr-messages 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 5d 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 — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Commit and PR Messages

Write history that future readers can scan, search, and trust. A diff shows what changed; the message must explain why.

Based on How to Write a Git Commit Message (Chris Beams) and A Note About Git Commit Messages (Tim Pope), adapted for SuperPlane's Conventional Commits + DCO requirements.

Language: Write commit bodies, PR titles (after the type prefix), and PR descriptions in ASD-STE100 Simplified Technical English style. Follow simplified-technical-english before you finalize wording.

When to use

  • Creating or amending a commit message
  • Opening or updating a pull request (title and body)
  • Reviewing whether a PR description is useful to reviewers

Commit messages — seven rules

  1. Separate subject from body with a blank line.
  2. Limit the subject line to ~50 characters (72 hard max). Prefer the Conventional Commits prefix used by this repo (feat:, fix:, chore:, docs:) plus a short imperative summary; keep the whole subject readable.
  3. Capitalize the subject line after the optional type prefix (feat: Add canvas console filters).
  4. Do not end the subject line with a period.
  5. Use the imperative mood in the subject line — as if completing: If applied, this commit will ________. Prefer Fix, Add, Remove, Refactor over Fixed, Adds, Fixing.
  6. Wrap the body at 72 characters.
  7. Use the body to explain what and why, not how. The code shows how. Cover motivation, prior behavior, trade-offs, and non-obvious side effects.

Model commit

Capitalized, short (50 chars or less) summary

More detailed explanatory text, if necessary. Wrap it to about 72
characters or so. The blank line after the subject is mandatory when a
body is present.

Explain the problem this commit solves and why this approach was chosen.
Leave mechanical how-details to the diff unless the approach is surprising.

Further paragraphs come after blank lines.

- Bullet points are okay

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.
