Skills That Ship
Skills are guided workflows you trigger with /. They orchestrate Rook’s tools
into multi-step processes — designing a Grasshopper definition, building a road
network, organizing a file. Rook ships 11 of them.
Grasshopper — the design cascade
Section titled “Grasshopper — the design cascade”The three skills that take a definition from idea to canvas (Rook records what it learns automatically). See The Design Cascade.
| Skill | What it does |
|---|---|
/design-grasshopper | Explore the idea, ask questions, produce a validated design document |
/plan-grasshopper | Turn that design into an exact, ordered build plan |
/execute-grasshopper | Build the plan in batches, checking errors as it goes |
Chirp — AI reasoning on the canvas
Section titled “Chirp — AI reasoning on the canvas”See Chirp.
| Skill | What it does |
|---|---|
/chirp | Create a single Chirp component (planner, critic, gate, …) |
/chirp-cascade | Build a multi-component reasoning cascade from a brief |
Roads & site
Section titled “Roads & site”RoadCreator-backed road design, from a single road to a whole network.
| Skill | What it does |
|---|---|
/design-road | Design and create a single 3D road from a centerline |
/masterplan-roads | Build a whole road network from multiple centerlines (surfaces, intersections, sidewalks, crossings, guardrails, slopes) |
Organizing & conventions
Section titled “Organizing & conventions”The everyday cleanup work. See Everyday Tasks.
| Skill | What it does |
|---|---|
/project-setup | Bootstrap a project directory with Rook instructions |
/capture-convention | Extract layer/material/block conventions from a reference file into .rook/conventions.yaml |
/clean-layers | Audit a file against your conventions and propose cleanup (never destructive without approval) |
/twisted-column | Create a parametric twisted column by lofting rotated profiles |
How skills compose
Section titled “How skills compose”The real power is chaining them. The Grasshopper cascade is the canonical example —
design → plan → execute — Rook records what it learns automatically. You can mix
freely: capture a convention, clean a file to match, then design new geometry on the
tidy base. Just describe the end-to-end goal and let your agent sequence the skills.
