Index your codebase.
Query with intent.
Give your AI agent the context it actually needs. LENS maps your repo — TF-IDF scoring, import graph traversal, co-change analysis — and delivers ranked files in one call. Fewer tokens wasted, smarter output.
$ npm install -g lens-engineHow It Works
Three commands. No API keys. Your code never leaves your machine.
Install & Start
Install the CLI globally and start the background daemon.
$ npm install -g lens-engine $ lens daemon start
Register & Index
Register a repo — indexing kicks off automatically. TF-IDF, import graph, and git history in one pass.
$ lens repo register Registered: my-project Scanning files... 847 files Building import graph... done Analyzing git history... done Index complete in 2.3s
Query
Ask with intent. Get a ranked context pack for your AI agent.
$ lens context "add auth middleware" Context pack: 12 files, 3.2KB src/middleware/auth.ts src/routes/login.ts src/lib/tokens.ts ...
Right Context, Right Code
AI agents are only as good as the files they see. LENS gives them exactly what they need — nothing more, nothing less.
Intent-Based Retrieval
Describe what you're building. LENS ranks every file by relevance using TF-IDF, path weight, exports, and docstrings — no keyword guessing.
Understands Structure
Import graph traversal, 2-hop dependency analysis, and hub-file boosting. Your agent sees the files that actually matter, not just string matches.
Learns from Git
Files that change together get surfaced together. Co-change analysis catches cross-cutting concerns grep never finds.
MCP Native
Drop a .mcp.json in your repo. Claude Code, Cursor, and any MCP-compatible agent auto-discover LENS. Zero configuration.
Your Code Stays Local
Everything runs on your machine. No code leaves your laptop. No cloud dependency. Works offline, works air-gapped.
One Call, Done
One context query replaces dozens of glob/grep tool calls. ~10ms cached, under 1s cold. Fewer tokens spent searching, more spent building.
