# Commit statistics

> Measure AI authorship, acceptance, and human edits for a commit or commit range.

Use `autter stats` to summarize authorship for the current commit, a specific commit, or a linear commit range.

## Show statistics

```bash theme={null}
# Current HEAD
autter stats

# One commit
autter stats 8f2c1ab

# Linear commit range
autter stats main..HEAD

# Machine-readable output
autter stats main..HEAD --json
```

## Read the metrics

| Field                  | Meaning                                                                       |
| ---------------------- | ----------------------------------------------------------------------------- |
| `human_additions`      | Added lines attributed to a human, including edited AI lines where applicable |
| `ai_additions`         | Added lines attributed to a coding agent                                      |
| `mixed_additions`      | AI-generated lines edited by a human before commit                            |
| `ai_accepted`          | AI-generated lines committed without a human edit                             |
| `total_ai_additions`   | All lines generated during the session, including discarded output            |
| `total_ai_deletions`   | All lines deleted by agents during the session                                |
| `time_waiting_for_ai`  | Wall-clock time spent waiting for agent responses                             |
| `tool_model_breakdown` | The same metrics grouped by agent and model                                   |

<Note>
  `human_additions + ai_additions` can exceed the raw Git additions when mixed lines count in both categories.
</Note>

## Use JSON in automation

```bash theme={null}
autter stats HEAD --json
```

```json theme={null}
{
  "human_additions": 28,
  "ai_additions": 76,
  "ai_accepted": 47,
  "git_diff_deleted_lines": 34,
  "git_diff_added_lines": 104,
  "tool_model_breakdown": {
    "codex/gpt-5": {
      "ai_additions": 76,
      "ai_accepted": 47
    }
  }
}
```

## Know the local limit

Local statistics are computed from commit-level Git notes. Large or nonlinear histories can take longer and may not represent pull request boundaries accurately.

Connect the Autter platform when you need repository, pull request, team, cost, or production-level aggregation.
