About this skill

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.
  • Default ports — memory uses :3038, search uses :7878. If those are occupied, the daemons will pick alternates and write the actual ports to ~/.trusty-*/address.json; the health checks in this skill assume the defaults.

Verification

Phase 4 runs scripts/verify-trusty.sh, which checks:

  1. Both binaries on $PATH.
  2. Both daemons responding to /health.
  3. .mcp.json (if present in CWD) references trusty server entries.
  4. On macOS, launchd plists exist under ~/Library/LaunchAgents/.

Verification must pass completely before Phase 5 records completion. A partial install (binary present, daemon down) will be re-detected on the next session and the wizard will offer to repair it.
