Extract layer, material, and block organization conventions from a reference Rhino file and write a .rook/conventions.yaml file. Use this skill whenever the user mentions: "capture convention", "extract convention", "save layer template", "create convention file", "layer standards", "what are my conventions", or when /project-setup offers to capture from a reference file. Also use when the user opens a "template" or "standard" file and wants to formalize its structure for reuse across projects.
Build reasoning cascades of Chirp components from natural language design briefs. Creates multiple LLM-embedded Grasshopper components with Reasoning pin fan-out for multi-discipline design coherence. Triggers: "chirp cascade", "reasoning cascade", "design language cascade", "chirp pattern", building multiple Chirp components that share reasoning context, setting up Wasp aggregation with semantic configuration, Wasp grammar authoring, graph-grammar cascade, production rule generation, or any workflow requiring coordinated LLM reasoning across GH components.
Create a single Chirp component on the Grasshopper canvas. Requires a category (planner, interpreter, critic, narrator, classifier, gate, editor) and a design context. Triggers: "chirp component", "add a chirp", "create a chirp planner", "chirp interpreter", "I need a critic", "add a gate", "chirp editor", or any request to create a single LLM-embedded Grasshopper component.
Compare a Rhino file's layer structure against its .rook/conventions.yaml and propose cleanup changes. Audit-first, never destructive without approval. Triggers: "clean layers", "cleanup layers", "fix layers", "organize layers", "layer cleanup", "apply convention", "check layer standards", or when the user has a conventions.yaml and wants to bring a file into compliance.
Collaborative Grasshopper definition design through exploration, Q&A, and incremental validation. Use when the user wants to build a GH definition, parametric model, or visual programming workflow. Triggers on: "design grasshopper", "create GH definition", "build parametric", "grasshopper workflow", or any request for a multi-component Grasshopper definition. Produces a design document that feeds into plan-grasshopper.
Design and create 3D roads in Rhino using the RoadCreator plugin, orchestrated through Rook's MCP tools and scripted commands. Triggers on: "create road", "3D road", "road design", "highway", "alignment", "road surface", "road from curve", or any request involving road centerlines, horizontal/vertical alignment, cross-sections, or road accessories (guardrails, slopes, markings). Bridges Rook's Rhino geometry tools with RookRoads computation tools and RoadCreator's scripted commands for a complete road design pipeline.
Execute a Grasshopper implementation plan by running MCP tool calls in batches with solve/error checkpoints between each batch. Use after /plan-grasshopper produces a plan doc, or when the user has an exact step-by-step tool call sequence to execute on the GH canvas.
Build a complete road network from centerline curves — 3D surfaces, intersections, sidewalks, crossings, guardrails, slopes, and 2D footprints. Orchestrates the full pipeline through six phases with user confirmation at decision points. Triggers on: "masterplan roads", "road network", "set up roads from centerlines", "create roads from curves", "build road network", "roads from these curves", or any request involving multiple road centerlines that need to become a coordinated road network with accessories. Use this skill instead of /design-road when the user has multiple curves that form a connected road network, not just a single road.
