Reviewing AI code: what commit history proves
Commits make changes traceable but do not prove that tests passed. Connect diffs, requirements and verification logs when reviewing AI-generated code.
What can you learn from a commit?
A Git commit records a repository snapshot, its parents and metadata such as author and message. Its diff shows changes against a comparison point. This helps reviewers inspect AI-generated code in steps. It does not prove that the change is correct or that project rules were followed.
An author field alone does not establish a verified identity. A plausible commit title describes an intention; it is not a verification log.
How do you inspect a change?
These Git commands inspect the current commit. Replace HEAD with a commit ID to inspect another revision:
git show --stat HEAD
git show HEAD
The first view shows the scope; the second shows the change in detail. The official git show documentation explains the commit message and diff output. Check for unintended files, configuration changes and secrets as well.
What other evidence belongs in a review?
- Requirement: Which acceptance criteria should this revision satisfy?
- Execution: Which build and test commands actually ran, and what were their results?
- Revision: Do those logs refer to the exact commit proposed for merging?
- Coverage: Which business cases and security risks remain untested?
Anvil Coder run reports supplement commit history. The Laravel reference run illustrates a limit: test files were generated, but execution could not be verified because the PHP toolchain was unavailable.
When are small commits useful?
Small work units make intentions easier to connect to changes. A sequence of small commits still needs an integrated review: interface problems and regressions may emerge only when the changes run together. Commit history supports review; it does not replace it.
