Core orchestration for disciplined AI-assisted development. Auto-invokes when starting new features, implementing tasks, or working on any development that should follow the spec-first, test-driven process. Triggers on task planning, feature implementation, bug fixes, refactoring work, or when beads/bd tasks are referenced.

Extract and generate coding best practices from PR review comments. Use when the user asks to "extract best practices", "analyze PR comments", "generate coding standards", "create best practices from PRs", or "update coding guidelines from reviews".

Java coding standards for Spring Boot services: naming, immutability, Optional usage, streams, exceptions, generics, and project layout.
