It uses a Retrieval-Augmented Generation (RAG) pipeline (hybrid search with vector + BM25 + reranking) and exposes functionality via an MCP server (19 tools), usable either hosted (via an MCP-remote URL and Bearer token) or self-hosted by running the MCP server locally.","best_when":"You want IDE-integrated, context-aware code generation for Arbitrum/Stylus/Orbit and are comfortable validating generated code (including compiling/verifying) before use.","avoid_when":"You need guaranteed deterministic outputs, strict API compatibility guarantees, or you cannot use an MCP tool-based interface/token authentication to access functionality.","last_evaluated":"2026-03-30T15:32:50.922310+00:00","has_mcp":true,"has_api":false,"auth_methods":["Bearer token (Authorization: Bearer YOUR_API_KEY) for hosted MCP-remote"],"has_free_tier":false,"known_gotchas":["Generated code should be compiled/verified; the project references a Docker-based cargo check verification utility, implying additional validation steps are expected.","Self-hosted usage requires generating the local ChromaDB vector store; MCP tools may fail until the vector DB exists.","Hosted MCP requires correct Authorization header configuration in the MCP client."],"error_quality":0.0}
