How It Works

Three steps. No API keys required. Everything runs locally.

01

Install & Register

Install the CLI globally, then register your repo.

$ npm install -g lens-engine
$ lens repo register /path/to/repo
02

Index

Build TF-IDF scores, import graph, and co-change analysis automatically.

$ lens index

Scanning files... 847 files
Building import graph... done

03

Query

Ask with intent. Get a context pack for your AI agent instantly.

$ lens context "add auth middleware"

Context pack: 12 files, 3.2KB
  src/middleware/auth.ts
  src/routes/login.ts
  src/lib/tokens.ts
  ...

Built for AI-Assisted Development

Every feature is designed to give AI agents the right context, fast.

TF-IDF Scoring

Code-domain stopwords, segment-aware path tokens. Filenames weighted 4x, directories 2x. Exports and docstrings included.

Import Graph

Forward/reverse imports, 2-hop dependencies, indegree boost for hub files. Dynamic file cap based on import depth.

Co-Change Analysis

Git history patterns surface files that change together. Cluster-based promotion for related modules.

MCP Integration

Claude Code auto-discovers LENS via .mcp.json. Zero configuration for MCP-compatible agents.

Local-First

SQLite database at ~/.lens/data.db. Zero network calls. Works offline, works everywhere.

Zero LLM Queries

Context packs in ~10ms cached, ~0.5-7s cold. No API calls, no token costs, no latency.
