threejs-object-sculptor

threejs-object-sculptor is a skill for Codex from linegel/threejs-complete-set-of-skill. It costs 47 tokens per session (1,658 once invoked), scanned A, original, ISC.

A guide for turning one or more reference images into procedural Three.js objects, meaning models generated by code rather than manually modelled. It keeps visible evidence separate from assumptions about hidden surfaces, sizes, materials, and moving parts.

In plain words
What is it for?
Use it to judge reconstruction feasibility, plan a procedural model, write its Three.js implementation, and structure it for animation, collision detection, or destruction.
Why use it?
It prevents a single image from being treated as proof of details it cannot show. It also clarifies when an exact reconstruction is impossible without more views or measurements.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

threejs-object-sculptor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/probe_reference_image.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Three.js Object Sculptor

Turn object images into an evidence-bound procedural reconstruction. The output may be a feasibility verdict, a build plan, or working code; every branch follows the same six stages.

Inputs and limits

Use every supplied view. If the target or intended use is ambiguous, resolve that ambiguity before committing to a representation. Otherwise, assume an interactive browser prop whose authored scale can be revised.

A single view determines only visible evidence. Hidden surfaces, thickness, absolute dimensions, material parameters, and articulation remain assumptions unless symmetry, known construction, extra views, or measurements constrain them. Label each assumption. Exact likeness, manufacturing dimensions, or an unseen mechanism requires the missing view or measurement; a stated stylized approximation is a valid alternative.

For a local image, set <skill-dir> to the directory containing this SKILL.md, then run python3 "<skill-dir>/scripts/probe_reference_image.py" "<image>" using probe_reference_image.py. It reports format, byte count, dimensions, aspect ratio, and metadata parsing status. That status describes file metadata only; visual inspection in stage 1 alone determines whether the pictured object is readable.

Six-stage sculpt

1. Inspect

Inspect every view before planning geometry. Record:

  • the target boundary, crop, resolution, blur, occlusion, transparency, and conflicting subjects;
  • visible front/up cues, camera projection clues, a scale anchor when one exists, and view-to-view consistency;
  • which contours, negative spaces, contacts, material regions, and repeated features are directly observed;
  • which hidden forms or physical properties remain assumptions.

Visual inspection alone assigns an evidence readability verdict:

  • readable: the target and its dominant silhouette are clear enough to choose a reconstruction;
  • conditional: a useful approximation is possible with named assumptions, reduced scope, or another view;
  • unreadable: target identity or defining form is too ambiguous for a defensible reconstruction.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
