Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00047 | $0.02047 |
| Opus 5.5 | $0.00019 | $0.00819 |
| Sonnet 5.5 | $0.00009 | $0.00409 |
| Haiku 4.5 | $0.00005 | $0.00205 |
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 1mo ago.
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.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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. The helper reads a bounded prefix
(default 1 MiB, --max-header-bytes up to 64 MiB) and reports file bytes and
scanned bytes separately. Its width/height are stored raster or canvas dimensions,
not EXIF-oriented, pixel-aspect-corrected, or decoded-image validation. A partial
result for a valid but unsupported or late header is not an unreadable object.
Supported headers are PNG IHDR, JPEG SOF before scan data, GIF logical screen,
WebP VP8/VP8L/VP8X, BMP CORE/Windows INFO families, and the first classic TIFF
IFD. BigTIFF and JPEG DNL height recovery are outside this helper. File validity,
all animation/page frames, orientation, and color remain separate inspections.
Header rules follow PNG,
WebP,
BMP CORE,
and the JPEG frame reader.
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

threejs-object-sculptor is a skill published in the GitHub repository linegel/threejs-complete-set-of-skill (11 stars, last pushed 1mo ago), licensed ISC. It adds 47 tokens to every session and 2,047 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
