Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| cad_reference_calibrationA | Calculates real-world millimeters from photo pixel measurements using a reference object (US Quarter 24.26mm, Penny 19.05mm, Credit Card, or Ruler). Also calculates 3D printing fit clearances (slide-fit, snap-fit). |
| cad_generate_battery_coverA | Generates a complete parametric 3D-printable battery cover (TV remote, controller, toy) with cantilever snap-fit clip, alignment retention prongs, and grip ribs. Emits both human-editable OpenSCAD (.scad) code and ready-to-print watertight binary STL (.stl). |
| cad_generate_bracketB | Generates a parametric structural mounting bracket (L-bracket, flat plate) with mounting screw holes and reinforcing 45-degree gussets. |
| cad_generate_knobB | Generates a replacement rotary knob with D-shaft socket, perimeter fluting, and pointer indicator notch. |
| cad_generate_spacerB | Generates a round or hexagonal standoff, spacer, or bushing with a central through-hole. |
| cad_inspect_stlA | Inspects a 3D STL mesh file for watertight manifoldness, triangle count, bounding box dimensions, volume, and estimated filament consumption in grams (PLA, PETG, ABS). |
| cad_check_systemA | Checks host environment for optional OpenSCAD CLI installation, default fit tolerances, and supported optical reference objects. |

Scored across 7 tools
Each tool targets a distinct operation: calibration, inspection, system check, and four distinct parametric part generators. The generate tools are clearly separated by object type (battery cover, bracket, knob, spacer), leaving no ambiguity.
All tools share the consistent `cad_` prefix, and most follow a verb_noun pattern (inspect_stl, generate_battery_cover, check_system). However, `cad_reference_calibration` uses a noun_noun format instead of a verb-led name, creating a minor deviation.
Seven tools is within the ideal range for a focused CAD generation server. Each tool serves a specific function without redundancy, making the count feel well-scoped and purposeful.
The set covers the core lifecycle: calibrate from reference, generate replacement parts, and inspect the resulting STL. It lacks more generic shape generators or modification tools, but for a replacement-part-focused CAD server, the coverage is solid with only minor gaps.
