v2.0.8 — cost opt: Opus + first-open + no MCP + simpler prompt
Summary
Cost-optimizes the Claude reviewer to ~3x cheaper while raising review quality:
- Opus 4.7 hardcoded — senior-engineer model for the single review
- First-open only — drops
synchronizetrigger; CodeRabbit + Codex handle per-push - No MCP inline tool — cuts 3-5k tokens/turn overhead; CodeRabbit covers inline review
- Simpler prompt — 3 sections (Critical / Security / Test coverage), defers style nits to CodeRabbit + Codex
--max-turns 15— headroom for Opus to complete simpler prompt
