pikuri-assistant ships the demo +bin/pikuri-assistant+ binary on top of pikuri-core + pikuri-skills + pikuri-mcp: an interactive chat agent the user hand-edits to declare a +Pikuri::Mcp::Registry+ of MCP servers. The +Pikuri.prompt+ search path picks up this gem's +prompts/pikuri-assistant.txt+ automatically on require — same multi-gem prompt-dir pattern as pikuri-code.
