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 | $0.00065 | $0.01956 |
| Opus 5.5 | $0.00026 | $0.00782 |
| Sonnet 5.5 | $0.00013 | $0.00391 |
| Haiku 4.5 | $0.00006 | $0.00196 |
Grade A, and why
threejs-black-holes-and-space-effects 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 2mo 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 — 165 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Curved-Ray Space Effects
This skill owns three native claims: an artistic deformation, an Ellis
null-geodesic solution, or a Schwarzschild null-geodesic solution. A Kerr
result is owned by an independently validated external solver; without one,
return unsupported-model. Numerical integration alone does not turn an
artistic field into a metric solution.
1. Select the claim
| Requested observable | Select | Conditional reference | Completion criterion |
|---|---|---|---|
| Stylized bending, bounded glow, or a decorative disk | Artistic bounded ray | Read artistic-rays-and-disks.md. | The implementation and its documentation say artistic, and fixed-view refinement bounds the visible change. |
| Traversal or turning through an ultrastatic spherical throat | Ellis wormhole | Read the Ellis section of metric-rays.md. | The throat scale, exterior mapping, invariant, and B < 1, B = 1, B > 1 regimes are explicit. |
| Nonrotating black-hole lensing or a physical thin-disk image | Schwarzschild | Read the Schwarzschild and physical-transfer sections of metric-rays.md. | The mass scale, horizon, photon sphere, critical impact, invariant, continuous events, and observer/emitter frames are explicit. |
| Rotating black hole | Unsupported here | Integrate an independently validated Kerr solver as an external ray/transfer producer; a lens map is an optional reuse form. | The solver supplies its metric/sign conventions, constants of motion, tetrads, event semantics, and independent convergence evidence; otherwise return an unsupported-model result. |
Complete when: exactly one claim owns the ray path, and every visual claim is no stronger than that branch's evidence.
2. Declare the numerical domain
Define before authoring the march:
- the effect-to-world transform and a finite local integration bound;
- the camera event, ray origin, normalized direction, and exterior side;
- one length basis for positions, steps, horizons/cores, and medium coefficients;
- the state vector, its integration parameter, its owner, and its valid time;
- the environment orientation and the orthonormal frame used for escaped-ray lookup;
- the pre-march results
miss,setup-rejected, andunsupported-model; applicable continuous horizon, core, disk, shell, and proxy-exit surfaces; and the invalid-state, opacity, step-cap, and attempt-cap outcomes.
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-black-holes-and-space-effects is a skill published in the GitHub repository linegel/threejs-complete-set-of-skill (11 stars, last pushed 1mo ago), licensed ISC. It adds 65 tokens to every session and 1,956 once invoked, about $0.0003 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.
