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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00168 | $0.10074 |
| Opus 5.5 | $0.00067 | $0.04030 |
| Sonnet 5.5 | $0.00034 | $0.02015 |
| Haiku 4.5 | $0.00017 | $0.01007 |
Grade A, and why
optimize-3d-scene 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 — 649 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Optimise a 3D scene
Every page that carries a three.js scene pays the same tax: a phone renders the same fragments as a workstation, the first frame after a shader appears compiles mid-scroll, and the render loop keeps running behind three sections of copy nobody is looking at. This skill fixes those in a fixed order — cheapest and highest-impact first. It was rewritten from optimisation passes on ~50 production sites; each rule says whether it is a rule (held on ≥ 3 sites) or observed (1–2 — try it, measure it, don't assume it).
Every step applies to a raw WebGL scene as much as a three.js one; only §0's
measurement primitives differ (three.js hands you renderer.info, a raw scene
you instrument yourself — which you must do before you can begin).
Before you fix anything, read obsidian/knowledge/fix-catalog.md and
obsidian/knowledge/pitfalls.md — the answer, and the trap next to it, may
already be written down. iOS / real-phone behaviour (toolbar resizes, context
loss, 120 Hz speed, gyroscope) is owned by mobile-device-qa; this skill links
to it where they meet.
Modules this starter already ships — use them, don't write a sixth copy:
| need | module |
|---|---|
one clock in seconds, dt-scaled easing (createFrameClock, perFrame, damp) |
src/lib/scene/per-frame.ts |
| a scene box that ignores the iOS URL bar | src/utils/stable-viewport.ts + src/components/common/scene-viewport.tsx |
WebGL context-loss recovery (keepSceneAlive, watchContext, releaseContext) |
src/lib/scene/webgl-context.ts |
| gyroscope tilt for a hero model on phones | src/lib/scene/device-tilt.ts |
| robot / reduced-motion switch | src/hooks/use-motion-off.ts, src/utils/bot-ua.ts, src/proxy.ts |
| device tier, ticker, visibility gate, 60 fps desktop draw gate, scroll lerp, disposal | references/patterns.md (copy-paste forms) |

What ships with it
1 file 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.

optimize-3d-scene is a skill published in the GitHub repository textura-agency/next16-claude-starter (145 stars, last pushed 23d ago), licensed Unlicense. It adds 168 tokens to every session and 10,074 once invoked, about $0.0007 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 2026-08-30.
