Verify A2 — Agent-Authored Contributions
Criterion Definition
| Level | Description |
|---|
| 0 | No agent-authored code in git history; all commits are purely human-written |
| 1 | Occasional co-authored commits; agents contributed to fewer than 25% of recent changes |
| 2 | Regular agent contributions; agents co-authored 25–75% of recent changes |
| 3 | Agents autonomously create pull requests; more than 75% of implementation work has significant agent involvement |
"Recent" = last 90 days or last 50 commits, whichever covers more changes.
Evidence to Gather
- Look at recent git history (last 90 days or last 50 commits) and count commits with agent co-authorship markers — lines containing "Co-Authored-By", references to Claude/Copilot/Anthropic, the 🤖 emoji, or "Generated with".
- Calculate the ratio of agent-co-authored commits to total recent commits.
- Check merge commits and CI workflow files for signs of automated PR creation by an agent.
Instructions
Gather the evidence described above and determine the fulfillment level for A2.
Key calculation: divide agent-co-authored commit count by total recent commit count to get the percentage.
Scoring guide:
- Level 0: Zero agent-authored commits in git history — no co-authorship markers, no bot commits, no agent-attributed changes.
- Level 1: Agent co-authorship markers exist in fewer than 25% of recent commits. Occasional use, not yet habitual.
- Level 2: Agent co-authorship markers exist in 25–75% of recent commits. Habitual use across a significant portion of implementation work.
- Level 3: Agent co-authorship markers exist in more than 75% of recent commits, OR evidence of autonomous PR creation (bot-authored PRs, agent-triggering workflows that open PRs).
Report in exactly this format:
A2 — Agent-Authored Contributions
