mozart_save_midi after editing — changes are in-memory until savedmozart_get_measures to verify your edits look correct before savingDesign electronic schematics and PCB netlists from Pi using SKiDL. Use for circuit creation, KiCad library parts, nets/buses, ERC, BOMs, SVG schematics, KiCad schematic export, and standalone SKiDL Python.
CAD modeling with build123d from Pi. Use when creating, inspecting, rendering, or exporting parametric 3D models, STL files, STEP files, enclosures, brackets, and other mechanical parts.
Schedule one-time or recurring agent jobs from Pi. Use when the user asks for cron-like reminders, recurring checks, scheduled prompts, or inspecting/completing scheduled jobs.
Track and manage issues using the dude MCP server. List, create, update issues. Track bugs, tasks, blockers, and problems within projects. Search for issues. Use when tracking bugs, creating tasks, managing blockers, recording problems, or working with issue hierarchies.
Manage development projects using the dude MCP server. List projects, view records by project, search across projects. Projects are auto-detected from git — no manual creation needed. Use when exploring project organization, starting work on a codebase, or needing project-level context.
Interactive issue review and grooming session. Pulls all issues for the current project and walks through them with the user to triage, update, resolve, or archive. Use when grooming a backlog, reviewing open issues, or cleaning up stale tasks.
