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

Total commits in the last 90 days

!git log --oneline --since="90 days ago" 2>/dev/null | wc -l || echo "(git not available or no history)"

Total commits (last 50, for young repos)

!git log --oneline -50 2>/dev/null | wc -l || echo "(no git history)"

Agent co-authored commits (last 90 days)

!git log --since="90 days ago" --format="%H %s" 2>/dev/null | head -5 || echo "(no recent commits)" !git log --since="90 days ago" --format="%B" 2>/dev/null | grep -ic "co-authored-by\|🤖\|generated with\|claude\|copilot\|github-actions\[bot\]" 2>/dev/null || echo "0"

Co-authored commit messages (sample)

!git log --since="90 days ago" --format="%s%n%b" 2>/dev/null | grep -i "co-authored-by\|🤖\|generated with claude\|copilot" | head -20 || echo "(no agent co-authorship markers found)"

Agent-authored commits in last 50 commits

!git log -50 --format="%B" 2>/dev/null | grep -ic "co-authored-by.*claude\|co-authored-by.*copilot\|co-authored-by.*anthropic\|🤖\|generated with claude" 2>/dev/null || echo "0"

PR descriptions indicating agent implementation (if PRs exist as merge commits)

!git log --since="90 days ago" --merges --format="%s %b" 2>/dev/null | grep -i "claude\|copilot\|agent\|🤖" | head -10 || echo "(no agent-attributed merge commits)"

Presence of autonomous PR-creation tooling

!ls .github/workflows/ 2>/dev/null && grep -l -i "claude\|copilot\|agent\|openai" .github/workflows/*.yml .github/workflows/*.yaml 2>/dev/null | head -5 || echo "(no agent-invoking workflows found)"

Instructions

Analyse the evidence 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).
