Commit message conventions

What you will learn

• Understand the core purpose of Commit message conventions
• Master the basic usage and common options of Commit message conventions
• Use a consistent commit message structure to improve log readability, release notes quality, and incident-time traceability.
• Understand key concepts: A practical structure
• Know when to use this feature and when to avoid it

Commit messages are long-term operational metadata, not just local notes.

Start with a problem

Your team has developed some Git habits over time, but you're not sure if they are optimal — or you've just been through an incident caused by a Git mistake and want to avoid repeating it.

A practical structure

<type>(<scope>): <summary>

In body text, include:

• why this changed
• what risk or follow-up remains

Before Commit

Define change scopeChoose type prefixWrite clear description

→git commit

A good message is not for yourself now, but for yourself in six months and your teammates.

Example

fix(auth): reject expired refresh token

Align backend token validation with new TTL rule.
Risk: may increase login retries for stale clients.

Team-level rules

1. start summaries with an action verb
2. explain motivation, not only file edits
3. mark breaking changes explicitly

!PR descriptions do not replace commit messages

PR context may be collapsed or lost over time. Commit history remains the durable searchable index.

Good follow-up reads

1. commit hygiene
2. prepare commits before pull request
3. small batch review

Try it yourself

1. Practice the commit-message-conventions command in a test repository and observe state changes before and after
2. Experiment with different options and compare the output differences
3. Simulate a real scenario where you would need to use this, and walk through the full process
