Jamie Tanna argues hand-writing commit messages forces ownership and explains the why better than LLMs
↗
Jamie Tanna explains why he continues to manually write Git commit messages instead of delegating the task to LLMs, emphasizing the value of explaining the reasoning behind changes and taking ownership of the code.
As AI agents increasingly automate code generation and commit messages, developers risk losing the context and self-review benefits that manual writing provides. Hand-writing messages forces a step back to verify understanding and ownership of the code, even when AI assisted the implementation.

Manual commit messages explain the why of a change, which is often missing from diffs and LLM-generated summaries that focus on the what.
The act of writing a commit message acts as a self-review mechanism to ensure the author actually understands the changes and has not tried to do too much in one commit.
Even when using AI-assisted code, writing the commit message manually forces the developer to take ownership and responsibility for the final result.
