osgrep - Semantic Code Search Skill

Overview

osgrep transforms code search from exact string matching to semantic understanding. It uses neural embeddings (Granite + ColBERT) with hybrid ranking (Vector + BM25 + RRF) to find code by meaning, not just tokens.

Core principle: grep finds strings, osgrep finds concepts.

When to Use This Skill

Activate osgrep when:

  • User asks to "find" or "search for" concepts (not exact strings)
  • Exploring unfamiliar codebases
  • Finding similar implementations across files/languages
  • Questions like "how does the code handle X?"
  • Architectural understanding ("show me all API endpoints")
  • Pattern discovery ("find retry logic examples")

DO NOT use osgrep when:
