Techniques

Forbidden jutsu built into the CLI

Six core techniques, each mastered to perfection. No bloat, no compromise — pure search power.

⚡

Rasengan Algorithm

Sparse N-grams

Variable-length energy spheres that concentrate query power. Port of GitHub Blackbird's sparse_ngrams — orders of magnitude better than naive trigrams.

👥

Sage Mode

Daemon Mode

Unix socket daemon keeps the index warm in memory. Sub-millisecond queries without disk I/O — like entering Sage Mode for permanent power access.

📦

Scroll of Knowledge

JSON Output

Structured JSON output for AI agents. Pipe results to Claude, Codex, or any tool without regex parsing. 35x fewer tokens than file content.

🛡️

Barrier Jutsu

38 Exclusions

Automatically excludes node_modules, target, vendor, .git, and 34 more noise directories. Search only what matters — like a perfect barrier jutsu.

🔄

Continuous Chakra

Auto-Build

ig auto-builds the index on first run. Watch mode rebuilds on file changes. Your index is always fresh — chakra flows uninterrupted.

🎯

Sharingan Precision

Regex Native

Full regex support via the Rust regex crate. The index filters candidates, full regex verifies. Every match is exact — no false positives escape.
