Agent Brain is a Claude Code marketplace plugin with a RAG backend that combines BM25, semantic, and GraphRAG search so coding agents can query private docs and code with relationship awareness.
About
Agent Brain Marketplace is a Spillwave Solutions Claude Code plugin for code-first RAG document and source search. It combines BM25 keyword, semantic vector, and GraphRAG indexes with slash commands and a FastAPI backend so agents retrieve docs, code, and structural dependencies accurately. Reach for it when default agent context is insufficient for large private codebases or documentation sets. Enable GraphRAG for relationship queries and run the server alongside the marketplace plugin for full hybrid retrieval.
- Hybrid BM25, semantic vector, and GraphRAG three-index search
- Slash commands: agent-brain-search, semantic, keyword, hybrid, graph, multi
- AST-aware code chunking and dependency queries like what calls X
- FastAPI server with per-project isolation and pluggable providers

How do I give my coding agent accurate search over private documentation and source code including dependency and caller relationships?
Add hybrid BM25, semantic, and GraphRAG document search to coding agents via slash commands and a FastAPI retrieval backend.
Who is it for?
Developers running Claude Code with large private repos who need hybrid keyword, semantic, and graph retrieval beyond built-in context.
Skip if: Small projects fully covered by IDE search or teams unwilling to host the Agent Brain FastAPI indexing server.
What you get
The agent receives ranked retrieval results from BM25, vector, and optional graph indexes scoped to the configured project.

FAQ
What search modes does Agent Brain support?
It offers semantic, keyword BM25, hybrid, graph-only, and multi-mode RRF fusion via slash commands and API query modes.
When should I enable GraphRAG?
Enable GRAPH_INDEX when you need dependency-aware answers such as what calls a function, what a module imports, or structural code relationships.
Does Agent Brain isolate projects?
Yes. Per-project configuration and indexes prevent context pollution between separate codebases or documentation corpora.
