What it does

|Pre-scan

Indexes your codebase into pre-compiled .ctx files with LanceDB vector embeddings. The UserPromptSubmit hook silently runs semantic search (fastembed + LanceDB) before Claude processes each query, injecting relevant ctx files and code chunks as context — zero tool calls needed. PreToolUse hooks intercept raw Glob/Grep to redirect agents to indexed context. Also provides lc_context, lc_search, and lc_impact MCP tools. Saves 80-95% of tokens vs raw file exploration.
