Author-Model Declaration

How to Declare

• Explicit (preferred): add an **Author-Model:** line near the top of the PR body — **Author-Model:** claude-opus-4-7
• Implicit fallback: a Co-authored-by: git trailer on any commit in the PR. Claude Code emits the trailer by default
• Human-authored PRs: **Author-Model:** human
• Mixed authorship: list every model that contributed, space-separated — **Author-Model:** human claude-opus-4-7

Precedence

• Every PR must carry a signal
• PR body Author-Model: wins when both exist (explicit beats implicit)
• Trailer-only: known display names normalize to canonical IDs (e.g., Claude Opus 4.7 → claude-opus-4-7); unknown display names are accepted as ad-hoc model IDs
• Neither present blocks the PR — the reviewer exits with REQUEST_CHANGES before reading the diff

Model Families

• claude-* → anthropic
• gpt-*, codex-* → openai
• gemini-* → google
• Unknown strings default to their own ad-hoc family

Mixed Authorship

• If any AI model contributed, the reviewer family must differ from every declared AI family (worst-case matching)
• **Author-Model:** human claude-opus-4-7 is claude-authored for family-mismatch purposes — the openai-family reviewer runs, the claude-family reviewer skips
• Declaration spans both paired reviewer families (e.g., gpt-5.4 claude-opus-4-7): both run as degraded fallback. Avoid co-authoring across both paired families to preserve cross-family review
• Declaration spans neither paired family (e.g., gemini-2.5, custom model, human-only): both paired reviewers run — both are cross-family relative to the author; the duplicate review is accepted noise
