Commit Description as a Thinking Tool
The author argues that manually writing commit descriptions serves as a critical thinking tool for verifying AI-generated code. While AI agents can produce code and messages, they often lack the full context to explain the reasoning behind specific decisions. By drafting the 'why' themselves, developers ensure they truly understand the changes and can identify temporary decisions with clear exit criteria.
- ▪Writing commit descriptions helps developers reflect on code changes and re-evaluate technical decisions.
- ▪AI agents may fabricate reasoning for commit messages when they lack access to full project context.
- ▪Manually writing the description allows developers to verify that the code aligns with the intended purpose.
- ▪Explicitly documenting temporary decisions and their exit criteria in commit messages aids future maintenance.

NOW READING Commit Description as a Thinking Tool 2026-09-30 Software Development #thoughts #agentic-coding Before the AI era, I wrote pretty long commit descriptions (or commit bodies) for major changes. It took me about five to ten minutes to draft and reread them to make sure I didn’t miss anything important. I did that for several reasons. I wanted to include all the useful information so readers wouldn’t have to hunt for it in multiple places. I wanted to explain what and, more importantly, why. The “what” summarizes the changes that are generally self-explanatory, but it gives a starting point for explaining the “why.” Sometimes, I write it in first person, like I am drafting a message for someone: “I did this because…”, “I am doing this until we…” etc.
