Claude Code plugin marketplace for learning Java frameworks by rebuilding them from source. Two approaches: API-first (outside-in) and Core-first (inside-out). AI agents analyze real framework code, generate structured learning outlines, and guide you through building simplified working versions with tests.
Designs API-first vertical slice implementations in simplified Java for features from any-language source projects by analyzing the source project's public API and internal call chains, then providing implementation blueprints with API contracts, technology mappings, depth layer mappings, top-down build sequences, and…
Deeply analyzes source projects in any language (Python, Go, Rust, Node.js, C#, Ruby, Java, etc.) from the outside in — starting from the public API surface that clients import and call, tracing each API method/function inward through dispatch, processing, and infrastructure layers, mapping call chains, identifying…
Designs inside-out implementations in simplified Java for features from any-language source projects — analyzes the source project's patterns and architecture (Python, Go, Rust, Node.js, C#, Ruby, Java, etc.), maps source constructs to Java equivalents, then provides implementation blueprints with class mappings…
Deeply analyzes source projects in any language (Python, Go, Rust, Node.js, C#, Ruby, Java, etc.) from the inside out — tracing execution paths, mapping type hierarchies, identifying core abstractions and integration points, and documenting the inside-out dependency structure to inform progressive learning outlines…
Reviews simplified Java implementations (reimplemented from any-language source projects) for correctness, proper integration points, source-to-Java technology mapping accuracy, test quality, tutorial accuracy, and adherence to the inside-out learning path conventions, using confidence-based filtering to report only…
Designs enterprise Java architecture for re-implementing source projects from any language — adapts stack based on project type (Spring Boot 4 for applications, plain Java 21+ for libraries/frameworks), creates technology mappings with Mermaid visualizations, designs module structure with proper Maven dependency…
Deeply analyzes source projects in any language (Python, Go, Rust, Node.js/TS, C#, Ruby, Java/Quarkus/Micronaut/Vert.x, etc.) — classifies project type (Application/Library/Framework), maps project structure and dependencies, identifies technologies for Java mapping, extracts business logic and API surfaces, and…
