Autopilot CAD Builder

Use this skill for CAD design turns from the main Autopilot Chat pane.

Objective

• Keep the user in chat while building CAD in realtime.
• Use structured CAD mutations only.
• Make progress deterministic and inspectable.
• Keep snapshot truth aligned with what is visibly rendered.

Required Tools

Use only:

• openagents.pane.list
• openagents.pane.open
• openagents.pane.focus
• openagents.pane.action
• openagents.cad.intent
• openagents.cad.action

Operating Contract

1. Ensure CAD pane is open/focused before CAD mutations.
2. Prefer intent_json with typed payloads over free-form prompt edits.
3. After each mutating intent, checkpoint with snapshot/status action.
4. Keep tool sequences short and deterministic.
5. If intent parse fails, retry once with stricter intent_json.
6. If CAD mutation fails, return concise user-facing remediation.
7. Never claim a 2x2 grid is visible unless snapshot truth confirms it.

Week-1 Canonical Prompt

Use this exact natural-language prompt when user intent is week-1 gripper build:

Create a basic 2-jaw robotic gripper with a base plate, two parallel fingers, and mounting holes for a servo motor. Make it 3D-printable and parametric for easy scaling.

Preferred intent_json For Week-1

Use strict typed payloads:

{
  "intent": "CreateParallelJawGripperSpec",
  "jaw_open_mm": 42.0,
  "finger_length_mm": 65.0,
  "finger_thickness_mm": 8.0,
  "base_width_mm": 78.0,
  "base_depth_mm": 52.0,
  "base_thickness_mm": 8.0,
  "servo_mount_hole_diameter_mm": 2.9,
  "print_fit_mm": 0.15,
  "print_clearance_mm": 0.35
}

For week-1 variants, require deterministic IDs in stable order:

• variant.baseline
• variant.wide-jaw
• variant.long-reach
• variant.stiff-finger

Set material per active variant with explicit SetMaterial calls and verify variant_materials map after each assignment.

Week-1 Build Sequence

1. openagents.pane.open for CAD.
2. openagents.pane.focus for CAD.
3. openagents.cad.intent with strict CreateParallelJawGripperSpec intent_json.
4. openagents.cad.intent for GenerateVariants with count=4.
5. Cycle active variant and call SetMaterial for each target variant.
6. Capture snapshot truth in single layout.
7. Toggle viewport layout (toggle_viewport_layout or toggle_layout) to quad.
8. Capture snapshot truth again and confirm all variants are visible.
9. Return final summary tied to checkpoint fields, not assumptions.

Snapshot Truth Contract

Before asserting layout/visibility, verify:

• design_profile == "parallel_jaw_gripper" for week-1 path.
• viewport_layout is single or quad.
• visible_variant_ids matches current rendered layout.
• all_variants_visible is false in single and true in quad.
• variant_materials map includes all four week-1 variant IDs.

Safety Rules

• Do not invent unsupported CAD intents.
• Do not claim completion without reading a CAD snapshot/checkpoint.
• Do not claim "all four variants are showing" unless all_variants_visible=true and visible_variant_ids includes all four IDs.
• Do not use non-openagents.* tools for CAD pane mutation.
