ClaudeHut — a 7-phase agentic workflow plugin for Java/Spring Boot backend engineers.
Plugin Claude Code
7-phase agentic workflow for Java/Spring Boot backends (over a pre-indexed codebase): discover → brainstorm → spec → plan → implement → review → learn, with complexity-tier fast lanes.
Agent
Generates 2+ genuinely distinct solution options and recommends one; returns the candidate enforcement set. Any problem type. Never writes code.
Agent
Message + API contract review — Kafka/Avro/Protobuf compatibility, consumer-driven contract tests, REST/gRPC back-compat. Read-only; spawned by claudehut:review.
Agent
Persistence correctness — JPA mappings, fetch strategies, migration safety, transaction boundaries. Read-only; spawned by claudehut:review.
Agent
Read-only codebase query agent for Discover — locates implementations and maps the modules a task touches. Reports only; never proposes fixes.
