# AI blame

> Use Autter as an AI-aware replacement for git blame.

`autter blame` shows the commit author and the coding agent responsible for each attributed line.

## Inspect a file

```bash theme={null}
autter blame src/services/review.ts
```

The output follows `git blame` conventions and adds AI authorship where available. Standard `git blame` flags remain available.

## Common examples

```bash theme={null}
# Blame a file at the current revision
autter blame src/services/review.ts

# Limit output to a line range
autter blame -L 40,80 src/services/review.ts

# Inspect a previous revision
autter blame HEAD~1 -- src/services/review.ts

# Produce machine-readable output
autter blame src/services/review.ts --json
```

## Use blame during review

AI blame helps you answer:

* Which agent session introduced this line?
* Did a human edit the generated code before commit?
* Which model produced the surrounding implementation?
* Is the same session responsible for related lines in other files?

Use prompt access according to your organization's permissions. Prompt content may be local-only, connected but restricted, or unavailable.

## Editor support

The Autter VS Code extension can display color-coded AI attribution in the gutter for VS Code and compatible editors such as Cursor, Windsurf, and Antigravity.

## JSON for tools

Use `--json` when building an editor, review tool, or internal analysis pipeline. Treat prompt and identity fields as sensitive data.
