Result:

### Follow these instructions to create a good commit message:

1. **Start with an imperative verb**:
    - Examples: Add, Update, Remove, Fix, Create, Adjust, Improve, Normalize, Simplify, Document, Change, Format, Refactor, Clean up, Rename, etc.

2. **Specify the target**:
    - Examples: workflow, documentation, configuration, test, method, helper, file, commit message, etc.

3. **Optionally provide context or additional details**:
    - Examples: to fix bug, for new feature, due to error, to improve readability, etc.

4. **Maintain concise and clear language**:
    - Ensure each message is specific and to the point.

Given this structure, here are some examples of how this model might look:

- `Add missing download path`
- `Update internal documentation`
- `Fix release notes spelling`
- `Remove mkdir call`
- `Create .phpstorm.meta.php`
- `Simplify test`
- `Normalize capitalization`
- `Format Markdown`
- `Refactor unit test to extend unit test case (12.5x faster)`

Using the above patterns, here is a generalized template:

```plaintext
[Verb] [Target] [Optional Context/Detail]
```

### Sample Generated Commit Messages

Using the template, here are a few sample commit messages:

1. `Add new API endpoint for user authentication`
2. `Update README to include setup instructions`
3. `Fix typo in configuration file`
4. `Remove deprecated methods from utility class`
5. `Create initial migration scripts`
6. `Adjust test cases to handle new validation rules`
7. `Document code with additional comments and examples`
8. `Format JSON response for better readability`
9. `Refactor database connection logic to use environment variables`
10. `Normalize header tags across all HTML files`
