shift: Skill for Claude Code

.agents/skills/commit/SKILL.md

commit is a skill for Claude Code, Codex from shift-editor/shift. It costs 58 tokens per session (1,151 once invoked), scanned A, original, Apache-2.0.

A set of rules for writing Git commits in the Shift codebase. It defines the commit format, release-note expectations, subject length, and how to group changes.

In plain words
What is it for?
Use it when staging changes, writing a commit message, or preparing commits for a pull request.
Why use it?
It keeps the project history consistent and makes commits easier to understand and use for release notes.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

This is shift-editor/shift's own configuration. It tells Claude Code and Codex how to work on shift itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything shift configures →

Reuse

Borrowing it

Nothing to install: this file belongs to shift-editor/shift. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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 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 1mo 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 — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/commit — How Shift commits are written

The goal is a git log --oneline that explains the project and gives Release Please clean input.

Commit syntax

Every subject uses Conventional Commits:

<type>[optional scope][optional !]: <concise imperative description>

Examples:

feat: add isolated Nightly builds
fix(workspace): preserve edits after failed export
refactor(renderer): share retained glyph ownership
feat(document)!: reject legacy workspace schemas

Use ! or a BREAKING CHANGE: footer only when callers, documents, or user workflows must change. Alpha permits breaking changes, but the commit must still explain them.

Allowed types

Type Use for Public changelog
feat New user-visible functionality Yes
fix User-visible bug fix Yes
perf Measurable performance improvement Yes
refactor Code change with no intended behavior change No
test Tests without production behavior changes No
docs Documentation only No
build Packaging, build scripts, native compilation No
ci CI and release workflows No
style Formatting only, not UI appearance No
chore Dependencies, tooling, and repository housekeeping No

Release Please uses merged conventional commits to update CHANGELOG.md, versions, tags, and GitHub release notes. Write feat, fix, and perf subjects for users rather than as file-level implementation summaries.

Do not manually bump the product version or edit generated release sections in an ordinary feature pull request. Release Please owns those changes in its release pull request. Use a Release-As: X.Y.Z footer only after the user explicitly approves a milestone transition.

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.
