conventional-commit is a skill for Claude Code, Codex from JanDeDobbeleer/oh-my-posh. It costs 47 tokens per session (1,076 once invoked), scanned A, original, MIT.

A guide for writing commit messages in the Conventional Commits format. A commit message records a set of changes in a version-controlled project.

In plain words
What is it for?
Use it whenever creating a commit to choose its type, optional scope, short description, and any required breaking-change note.
Why use it?
It makes change history predictable and helps tools understand whether a change is a feature, fix, documentation update, or another kind of work.

About the project

oh-my-posh is a customizable prompt theme engine that renders command-line prompts across shells and platforms. Developers and terminal users use it to configure primary, secondary, right, and transient prompts in shells such as PowerShell, zsh, Bash, and cmd. The catalogue entries provide skills, instructions, agents, and an MCP integration for working with oh-my-posh.

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-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 6d 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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Conventional Commit

Commit Message Structure

<type>(<scope>): <description>

[optional body]

[optional footer(s)]

Types

Type When to use
feat A new feature
fix A bug fix
docs Documentation changes, no code
style Formatting, missing semicolons, etc. (no logic change)
refactor Code change that is neither a fix nor a feature
perf Performance improvement
test Adding or correcting tests
ci CI configuration changes
chore Maintenance tasks (updating deps, tooling, etc.)
revert Reverts a previous commit

Append ! after the type/scope to signal a breaking change: feat!: or feat(api)!: When a change breaks existing behavior, both markers are mandatory: the ! suffix on the type and the BREAKING CHANGE: footer. They always appear together — never one without the other.

Scope

Optional. Use the name of the area affected, e.g., segment, cache, config, ui. Omit when the change is truly cross-cutting.

Description

  • Required. One short imperative sentence, no period at the end. The full header line (type + scope + description) must be 72 characters or fewer. Aim for 50 characters or fewer for the description itself — this almost always keeps the full header within budget regardless of type and scope length.
  • Use the imperative mood: "add", not "added" or "adds". Never past tense or present-third-person: ✗ added, fixed, bumped, implemented → ✓ add, fix, bump, implement.
  • Never mirror the input's phrasing. If the request uses past-tense words (updated, added, bumped, was removed, got regenerated), convert them to imperative before writing the description: update, add, bump, remove, regenerate.

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.
