SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill solves the navigation bottleneck in complex Java microservice estates where traditional grep or vector-only search fails to capture structural relationships like dependency chains, service boundaries, and call hierarchies.

Core Features & Use Cases

  • Graph-Native Navigation: Perform precise structural queries like finding all callers of a method, tracing HTTP/async call chains across services, or identifying interface implementations.
  • Hybrid Search: Combine semantic vector search for fuzzy discovery with deterministic AST graph traversal for exact structural analysis.
  • Use Case: When refactoring a shared service, use this skill to map the entire impact surface by identifying every controller, client, and message producer that depends on a specific method or configuration.

Quick Start

Use the explore-codebase skill to find all controllers in the billing service that call the payment processing method.

FAQPage Schema
How do I trace dependencies and call hierarchies across Java microservices?

Trace dependencies across Java microservices by combining AST graph navigation with file-system search to map structural relationships and resolve call chains. This graph-native approach walks call graphs to identify callers and interface implementations.

Why does grep fail to find structural relationships in a microservices codebase?

Grep fails to find structural relationships because it only matches textual patterns and misses dependency chains or service boundaries. Graph-based AST traversal resolves symbols and walks call graphs to capture exact structural connections that text search cannot.

What is the best way to assess the impact of refactoring a shared Java service?

Assess refactoring impact by mapping the entire dependency surface using AST graph traversal to identify every controller, client, and message producer linked to a specific method. This determines the exact blast radius of your changes across the codebase.

Can I use AST graph traversal with file-system search for Java route discovery?

Yes, you can perform route discovery by combining semantic vector search for fuzzy discovery with deterministic AST graph traversal for exact structural analysis. This hybrid search approach traces HTTP and async call chains across microservices while falling back to grep for textual patterns.

Does this codebase exploration approach require write access to analyze Java microservices?

No, this codebase exploration approach provides universal read-only analysis of Java microservices without requiring write access. It leverages jrag MCP primitives to resolve symbols and walk call graphs safely for dependency tracing and impact assessment.
