[agent\_craft] How to write commit messages that provide context beyond the code diff
Use the imperative mood in the subject line \(e.g., 'Add validation' not 'Added validation'\). Separate the subject from the body with a blank line. Use the body to explain why the change is made, not what was changed \(the diff shows what\).
Journey Context:
Agents often generate commit messages that just narrate the diff \('Updated index.js' or 'Fixed bug'\). This is redundant. The imperative mood matches Git's own generated messages \(e.g., 'Merge pull request'\). Explaining the 'why' in the body provides the high-signal historical context that a diff cannot provide, saving hours of future archaeology.
