Generating Commit Messages

SkillDev tools

MANDATORY skill for ALL commits. Must be used EVERY TIME before creating any git commit. No exceptions.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Generating Commit Messages skill

Mandatory Process

BEFORE ANY git commit COMMAND:

  1. ALWAYS run git diff --staged first to see changes
  2. ALWAYS analyze the staged changes thoroughly
  3. ALWAYS split the code changes into atomic commits, one per coherent / cohesive change. Tests for a change should be in the same commit as the change itself. A single feature spanning multiple files (module + view + test) is ONE cohesive change — do not split it by file. Only split when changes are truly unrelated (e.g. a bug fix + a new feature + a docs update)
  4. ALWAYS run the checks relevant to the change before committing (there are no test/lint/format scripts — invoke the binaries with npx; yarn vitest/yarn eslint/yarn prettier fail on Yarn 4):
    • Tests: npx vitest run <path> when a *.test.ts covers the change (isolate with a path or -t '<name>')
    • Types/Svelte: yarn svelte-check when .svelte/.ts typing is affected (this one is a real script)
    • Lint: npx eslint <changed files>
  5. ALWAYS generate a commit message following the format below
  6. NEVER commit automatically as a side effect of making code changes. Only commit when the user explicitly invokes the commit skill or says "commit".

Confirmation Before Committing

--auto (caller runs autonomously): skip all approval/confirmation waits here (commit-plan gate below + fixup/rebase) — commit directly. Diff review, atomic splitting, checks, message format unchanged.

User trust requires seeing the plan before execution. Always present the full commit plan and wait for explicit approval before running any git commit command.

For each commit (regular or fixup), present:

  • The commit message (header + body if applicable)
  • The list of files included
  • If splitting into multiple commits: the full split plan (which files go in which commit, in what order)
  • If fixup: which commit SHA it targets and why

Then ask the user to confirm. Do not proceed until they approve. If they request changes to the message or grouping, adjust and re-present.

This applies equally to regular commits, fixups, and any commits triggered during the open-pr workflow.

Auto-Fixup Detection

Before creating a new commit, check whether the staged changes should be fixup'd into a recent commit on the current branch.

Process:

  1. Run git log main..HEAD --oneline to list all commits on the branch since diverging from main
  2. For each staged file, check git log main..HEAD -- <file> to see if it was modified in a recent branch commit
  3. If a staged change clearly amends or extends code from a previous commit (same file, nearby lines, related logic — e.g. fixing a typo introduced in a prior commit, adding a missing import for a recently added module), suggest fixup'ing into that commit
  4. Present the suggestion: "This change to <file> looks like it should be fixup'd into <sha> <message>. Want me to fixup instead of creating a new commit?"

When fixup is confirmed:

  1. Run git commit --fixup=<sha> (with user confirmation)
  2. Then run GIT_SEQUENCE_EDITOR=true git rebase --interactive --autosquash main to squash immediately (with user confirmation before the rebase)

If the change doesn't clearly relate to a previous commit, proceed with a normal new commit.

Required Commit Message Format

This repo uses Conventional Commits (enforced by the @commitlint/config-conventional config inline in package.json). The format is fixed:

<type>(<scope>): <subject>
<BLANK LINE>
<body>
<BLANK LINE>
<footer>

The header is mandatory; scope, body, and footer are optional.

Header

Shape: <type>(<scope>): <subject>

  • <type> is one of: build ci docs feat fix fix-next perf refactor release style test
  • <scope> (optional) is the affected area — usually a feature under app/components/ or a service under app/services/ (e.g. ocr, pdf, camera, sync, settings, security, edit, pkpass). When a change is platform-specific, prefix the scope with the platform: android/sync, ios/camera
  • <subject>: imperative present tense ("change" not "changed"), lowercase first letter, no trailing period
  • No line may exceed 100 characters

Examples:

docs(README): add build setup steps for submodules
fix(ios/camera): correct preview orientation on rotation

Body

ONLY add a body when the header alone isn't enough for a reviewer:

  1. Use the imperative present tense, same as the subject
  2. Explain WHAT changed only if the commit touches more than 3 files
  3. Explain WHY — the motivation, contrasted with previous behavior
  4. Keep every line under 100 characters

Footer

  • Reference the issue this commit closes: Fixes #<issue> / Closes #<issue>
  • Breaking changes start with BREAKING CHANGE: followed by a description and migration path

Revert

A commit that reverts another begins with revert: followed by the reverted header. The body states This reverts commit <hash>.

Co-Authored-By

Only add a Co-Authored-By trailer when Claude actually wrote the code being committed. If the user wrote the changes themselves (and Claude is just committing), do not add it.
