conventional-commits

conventional-commits is a skill for Claude Code, Codex from pantheon-org/tekhne. It costs 106 tokens per session (2,298 once invoked), scanned A, original, MIT.

A guide for writing Git commit messages in the Conventional Commits format, a shared pattern that labels changes such as features, fixes, and breaking changes. The format helps tools understand a project's history.

In plain words
What is it for?
It helps write commit messages, describe staged changes, create changelog entries, and mark changes that affect version numbers.
Why use it?
It removes guesswork from commit wording and makes commit history easier to group into changelogs and version updates.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

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 8d 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 — 188 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mindset

Conventional Commits exist to make commit history machine-readable. The type prefix is a contract: feat triggers a MINOR version bump, fix triggers PATCH, and ! or BREAKING CHANGE: triggers MAJOR. Every commit is a semantic event, not just a description of code changes.

Write the header for the person reviewing a CHANGELOG six months from now, not for yourself today. The body explains why — the code already shows what.

A less obvious implication: scope consistency drives changelog quality more than type correctness. A perfectly typed feat with an ad-hoc scope like feat(getUserById): produces a one-line changelog group with no neighbours. Establish a fixed scope vocabulary early — see Scope Naming and Commit Strategy.

When to Use

Apply when the user asks for help writing commit messages, wants to format staged changes as a commit, needs a CHANGELOG entry, or mentions conventional commits, semantic versioning, or version bumps.

When not to use: skip this skill if the project explicitly avoids Conventional Commits (e.g. uses Angular-style without the spec, or enforces a custom pattern via a project-specific hook). Do not override confirmed project conventions.

Procedure

  1. Inspect the change — read the diff or the user's description. Identify whether it adds new behaviour, fixes existing behaviour, or neither.
  2. Choose the type — use the Type Reference table. Decision rules for common ambiguities:
    • refactor vs feat: does the user gain new capability? If yes → feat
    • fix vs refactor: does the change correct wrong behaviour? If yes → fix
    • perf vs refactor: is there a measurable latency/throughput improvement? If yes → perf
    • chore vs anything else: if another type fits, use it — chore is the last resort
    • Multiple types needed? Split into multiple commits (see Atomic Commits)
  3. Pick the scope — use the module, package, or layer name (e.g. auth, checkout, api). Omit scope when the change is truly cross-cutting. Use a fixed vocabulary if the project defines one. See scope naming for conventions.
  4. Draft the header — imperative mood, lowercase, ≤ 72 characters. Verify with: "If applied, this commit will <header>."
  5. Add a body if needed — only when the why is not obvious. Explain the reasoning, not the implementation. Wrap at 72 characters.
  6. Add footersCloses: #N for issue references; BREAKING CHANGE: <description> whenever the public API surface changes. Always pair ! with a BREAKING CHANGE: footer.
  7. Verify before committing — run git commit --dry-run or your local commitlint hook to catch formatting violations before they enter history.

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 pantheon-org/tekhne (10 stars, last pushed yesterday), licensed MIT. It adds 106 tokens to every session and 2,298 once invoked, about $0.0005 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 2026-09-03.
