## What it is
osgrep is a local, grep-like semantic search CLI for codebases, built for AI coding agents. It uses local embeddings (ColBERT via onnxruntime-node) to answer natural-language queries and trace call graphs, with plugins for Claude Code and OpenCode.

## Use cases
- semantic code search with natural language queries
- find where authentication is handled in a codebase
- trace function call graphs for impact analysis
- reduce LLM token usage when agents explore code
- index repositories locally for private code search
- list symbols and code roles in a project

## When to choose
- you want grep-style speed but semantic, concept-level code search
- you need fully local, private embeddings without cloud APIs
- you use Claude Code or OpenCode and want agent-ready search output
- you need call graph tracing and symbol role detection

## When to avoid
- you only need exact string matching that plain grep already handles
- you cannot spare ~150MB for local embedding models
- you need cloud-scale search across many remote repositories
