Check if system meets requirements for Ollama embeddings.

Verifies: macOS, Apple Silicon (M1/M2/M3/M4), RAM, Homebrew. Use before attempting Ollama setup.

Install Ollama via Homebrew (macOS).

Requires Homebrew pre-installed. Uses 'brew install' and 'brew services'. PROS: Auto-updates, pre-built binaries, managed service. CONS: Requires Homebrew, may prompt for sudo on first install.

Install Ollama via direct download (macOS).

Downloads from ollama.com to ~/Applications. PROS: No Homebrew needed, no sudo required, fully headless. CONS: Manual PATH setup, no auto-updates.

Check Ollama server status and available models.

Returns whether Ollama is running and if the embedding model is available. Use to check if semantic/vector search is available.

Search Claude conversation history using hybrid search.

Combines FTS5 full-text search, macOS Spotlight content indexing, and optional vector similarity (requires Ollama). Supports natural language, keywords, and "exact phrases".

Examples:

• "authentication bug" - finds conversations mentioning both words

• "how to deploy" - semantic search finds related discussions

• project:"my-app" query:"database" - filter by project

List recent Claude conversations from the index, sorted by modification time.

Get full content of a specific conversation by session ID.

List all projects with conversation history, showing reconstructed paths.

Get statistics about conversation history and search capabilities.

Rebuild the conversation index and optionally generate embeddings.
