QuartzCouncil

An opt-in, on-demand AI pull request reviewer triggered by /quartz review commands on GitHub PRs. Uses a multi-agent "review council" architecture where specialized reviewer agents analyze code in parallel, then a moderator deduplicates and publishes high-signal inline comments and a summary. Deployed on AWS Lambda with SQS for async processing and DynamoDB for idempotency.

• Multi-agent review council with specialized reviewers running in parallel
• Amethyst agent for TypeScript type safety (unsafe casts, missing null guards, any misuse)
• Citrine agent for React/Next.js performance and architecture patterns
• Chalcedony agent for repo-specific conventions via .quartzcouncil.yml config
• Quartz moderator for deduplication, comment limiting, and summary generation
• Inline comments snapped to valid diff lines with severity levels
• Quality controls: hedging filter, false positive detection, Jaccard deduplication
• Rate limiting, idempotency checking, and token usage tracking with cost estimation
