Integrations

🦉 Owl-CLI — Semantic Code Search in Your Terminal

Repository: https://github.com/Shun0212/Owl-CLI

Owl-ph2-len2048 is the embedding backbone of Owl-CLI, a command-line tool for semantic code search powered by dense retrieval.

Owl-CLI indexes your codebase at the function level, encodes each function using this model, and performs vector similarity search to find relevant code for natural language queries — directly from your terminal.

Key Features

Example: Query Routing

Example: Interactive Session

Quick Start

# Install
git clone https://github.com/Shun0212/Owl-CLI.git

# Index your codebase and search
owl search "function that handles authentication"

# JSON output for tool integration
owl search "parse config file" --json

# Start MCP server for AI agent integration
owl mcp
