Synopsis

/openshift-developer:git-commit-format

Description

Applies conventional commit formatting rules when generating commit messages. This skill is loaded as context for other skills and workflows — it defines the commit message format, required footers, and validation rules.

Implementation

Commit Message Format

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

[optional body]

[footers]

Commit Types

• feat: New features
• fix: Bug fixes
• docs: Documentation changes
• style: Code style changes (formatting, etc.)
• refactor: Code refactoring (no functional changes)
• test: Adding/updating tests
• chore: Maintenance tasks
• build: Build system or dependency changes
• ci: CI/CD changes
• perf: Performance improvements
• revert: Revert previous commit

Breaking Changes

With ! to draw attention:

feat!: send email when product shipped

With BREAKING CHANGE footer:

feat: allow config to extend other configs

BREAKING CHANGE: `extends` key now used for extending config files

Required Footers

Signed-off-by

ALWAYS include Signed-off-by footer with name and email.

Get credentials in this priority order:

1. Environment variables: $GIT_AUTHOR_NAME and $GIT_AUTHOR_EMAIL
2. Git config: git config user.name and git config user.email
3. If neither configured, ask user to provide details

Commit-Message-Assisted-by

ALWAYS include when Claude assists with creating or generating the commit message:

Commit-Message-Assisted-by: Claude (via Claude Code)

Gitlint Validation Rules

• Run make run-gitlint to validate commit messages (if the repo has a gitlint target)
• Title line: 120 characters maximum
• Body line: 140 characters maximum per line
• Use conventional commit format
• Include required footers (Signed-off-by)
• No trailing whitespace

Return Value

• Commit message: A conventional commit message with type, scope, description, body, and all required footers

Examples

1. Simple commit:

   docs: correct spelling of CHANGELOG
   
   Signed-off-by: Jane Doe <[e-mail]>
   Commit-Message-Assisted-by: Claude (via Claude Code)
   

2. With scope:

   feat(azure): add workload identity support
   
   Signed-off-by: Jane Doe <[e-mail]>
   Commit-Message-Assisted-by: Claude (via Claude Code)
   

3. Multi-paragraph with footers:

   fix: prevent racing of requests
   
   Introduce request ID and reference to latest request. Dismiss
   incoming responses other than from latest request.
   
   Remove timeouts which were used to mitigate racing but are
   obsolete now.
