# ⚡ SKRT — Skill Router for AI Agents

**Blazing-fast skill routing engine for AI coding agents.**

SKRT discovers, indexes, and routes agent skills in under 50ms — no Python, no heavyweight dependencies, and graceful local fallback when no API key is configured.

Works with **Antigravity**, **Claude Code**, **Codex**, **Cursor**, **Cursor CLI**, and any agent that uses [SKILL.md files](https://docs.anthropic.com/en/docs/claude-code/skills).

## ✨ What It Does

AI coding agents like Claude Code and Cursor CLI use **skills** — specialized instruction files that extend their capabilities. With 100+ skills installed, agents waste context budget listing them all. SKRT solves this:

```
Input:  "用NotebookLM查找资料"
Output: nlm-skill (score: 92, 50ms)
```

**7-strategy matching engine:**
1. 🎯 Exact name match (100 pts)
2. 🔗 Name/query containment (90 pts)
3. 📝 Description substring match (up to 95 pts)
4. 🔑 Keyword token overlap (up to 80 pts)
5. 🔍 Individual token search (up to 92 pts)
6. 📐 Fuzzy Levenshtein matching (up to 40 pts)
7. 🀄 CJK bigram matching (up to 75 pts) — full Chinese/Japanese/Korean support

**🌐 Cross-language translation (Layer 0):**

When a query contains CJK (Chinese/Japanese/Korean) or Cyrillic (Russian/Ukrainian) characters, SKRT automatically translates it to English via Cursor API before matching — enabling accurate skill discovery regardless of query language.

```
Input:  "小红书运营"
Translated → "Xiaohongshu operation"
Output: agency-xiaohongshu-specialist (score: 87)
```
