What it does

Commit And PR Messages is an agent skill from superplanehq/superplane. Write Git commit messages and pull request titles/descriptions using the Chris Beams / Tim Pope conventions (subject/body split, ~50-char subject, imperative mood, why-not-how body) plus ASD-STE100 Simplified Technical English for bodies and PR descriptions. Use when creating commits, drafting or editing PR descriptions, writing PR titles, or when the user asks for help with commit/PR wording, changelogs from commits, or git history style.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Pull requests, Commit messages and Git workflow. The repository describes itself as: Open source factory for one-shot engineering.

When your agent uses it

  • Creating commits
  • Editing PR descriptions
  • Writing PR titles
  • The user asks for help with commit/PR wording

Example prompts

  • “/commit-and-pr-messages”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Separate subject from body with a blank line.
  2. Limit the subject line to ~50 characters (72 hard max). Prefer the
  3. Capitalize the subject line after the optional type prefix
  4. Do not end the subject line with a period.
  5. Use the imperative mood in the subject line — as if completing
  6. Wrap the body at 72 characters.
  7. Use the body to explain what and why, not how. The code shows how.

What it can do on your machine

Read from SKILL.md and the folder at commit 3023553. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • cbea.ms
    • tbaggery.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Commit And PR Messages loads about 1.6k tokens when it runs. Until then it costs about 117 tokens; SKILL.md has 744 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~117
When it runs · the whole SKILL.md, loaded when a task matches
~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 744 words (~1,638 tokens).

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