CodeSeeker Knowledge Graph

Semantic and keyword code search over your repo, with the import graph followed and duplicates and dead code found.

LABSCO SUMMARY

Search that understands "find the auth logic", not just files containing the word auth.

The value is in the fusion: keyword search finds the exact symbol, embeddings find the paraphrase, directory summaries answer questions about a whole area, and the graph then pulls in the files that are structurally connected rather than textually similar — so the answer includes the caller nobody named. The cost is the initial index, which runs on first use rather than on a schedule someone has to remember.

What it is

A code-intelligence index for a repository, behind a single tool with five actions. Search fuses BM25 with vector embeddings and directory summaries, then expands along the import, call and extends edges of a knowledge graph built from parsed ASTs; the same tool does symbol lookup, graph traversal, analysis and index management.

What you get

  • Hybrid search: BM25 with CamelCase tokenisation fused with vector embeddings by reciprocal rank fusion, with directory summaries surfacing for abstract questions and narrowing the results to one directory when it clearly matches
  • Graph expansion over the top results, following imports, calls and extends, so structurally connected files come back beside the textually similar ones
  • Symbol lookup by exact or partial name, optionally with its resolved relationships
  • Graph traversal from a seed file or from a semantic query, inward, outward or both, across imports, exports, calls, extends, implements, contains, uses and depends_on, to whatever depth you set
  • Duplicate and near-duplicate code found across the codebase at a similarity threshold you choose
  • Dead code detected — unused exports, functions and classes — along with god classes, circular dependencies, feature envy and coupling
  • The project's own detected coding standards for validation, error handling, logging and testing
  • Index management: initialised, synced for specific files, paths excluded or re-included, and status with file and chunk counts
  • Scoring that puts definitions above tests — source files boosted, test files penalised, filename matches boosted, files with several hits boosted

Requirements

Node with npx: npx -y codeseeker serve --mcp is the documented configuration, and a global npm install adds an installer for VS Code, Cursor and Windsurf. Nothing to configure — the project indexes itself the first time a tool touches it, which takes anywhere from 30 seconds to several minutes depending on size, and stays in sync afterwards. Relationship extraction is strongest where a real parser exists: Babel for TypeScript and JavaScript, tree-sitter for Python and Java, both installing themselves when needed, with regex extraction covering C#, Go, Rust, C, C++, Ruby and PHP.

Setup effort

One command — npm install -g codeseeker
