Trusty Services

This is a migration subskill. It declares WHAT to install in its frontmatter. The HOW lives in the parent protocol: migration-wizard/SKILL.md.

Always load the migration-wizard protocol before executing this skill. The five-phase wizard (user choice → detect → check → install → verify → complete) is defined there, not here.

Why install these?

trusty-memory and trusty-search are optional Rust services that give claude-mpm two capabilities the base install lacks:

• trusty-memory: persistent, hierarchical knowledge graph (palace / wing / room / closet / drawer) that survives across sessions. Lets agents remember context from previous conversations without re-explaining.
• trusty-search: hybrid semantic + BM25 + knowledge-graph code search with RRF fusion. Drop-in replacement for mcp-vector-search with better recall on large codebases.

Together they raise the ceiling on what cross-session workflows can accomplish — but they require Rust, ~2GB disk, and a one-time setup pass, which is why they ship as a migration skill rather than a default dependency.

What to expect during install

The protocol's Phase 3 delegates to scripts/install-trusty.sh, which:

1. Prefers claude-mpm setup trusty-memory trusty-search (the consolidated command that handles cargo install, launchd plist creation, and .mcp.json wiring atomically).
2. Falls back to per-binary claude-mpm setup <name> on older claude-mpm.
3. Falls back to raw cargo install if claude-mpm is unavailable; in that case daemon startup and MCP wiring become manual steps.

A typical install takes 3-8 minutes (mostly cargo compile time).

Known gotchas

• macOS, linker 'cc' not found — install Xcode Command Line Tools with xcode-select --install, then retry.
• cargo install SSL error — usually a corporate proxy. Configure CARGO_HTTP_PROXY and retry.
• Address already in use — a previous daemon is still running. Run pkill -f trusty-memory; pkill -f trusty-search and retry.
