Three ways in

• The guard — a hook that answers when the agent runs an install command or edits a manifest, refusing only what is never right.
• The skills — procedures loaded on demand, installed at the path each host actually reads.
• The MCP server — 31 tools and 18 workflow prompts over live data, one URL and one header, no install.
