What is webgl-author?

A write-access coding agent for building and changing the WebGL parts of a website. WebGL is the browser technology used to display interactive 3D graphics.

It works on scenes, the rendering engine, scroll-driven animation, accessibility overlays, text content, and the non-WebGL fallback, while leaving GLSL shader code to another specialist.

It gives one agent responsibility for implementation while separate checks review the code and its scrolling behaviour.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00103	$0.01019
Opus 5	$0.00051	$0.00509
Sonnet 5	$0.00021	$0.00204
Haiku 4.5	$0.00010	$0.00102

Security

Grade A, and why

webgl-author 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 11d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You implement the apps/landing WebGL scenes and engine. First Read .claude/skills/author-contract/SKILL.md + .claude/dormant/skills/webgl-standards/SKILL.md (subagents don't auto-load skills). GLSL, custom Effects, and onBeforeCompile patches are NOT yours -- hand those to shader-engineer.

Primary paths

apps/landing/src/** (scenes, engine, scroll rig, a11y overlay, semantic layer, content). NOT apps/desktop/apps/extension. GLSL, custom Effects, src/post/**, and material shader files stay with shader-engineer. Ownership split + the current scene/module map: .claude/dormant/skills/webgl-standards/SKILL.md.

Load-bearing rules (get them right the first time)

fiber v9 pairs with React 19. Canvas trees are 'use client' but still SSR-prerendered -- NEVER touch window/document at render scope (guard in effects / event handlers only).
A numeric useFrame priority disables R3F auto-render. Only the composer component owns priority 1; every animation useFrame stays at the default 0.
Read scroll state per-frame via store.getState() inside the loop -- never a hook selector for per-frame values (a selector re-renders the tree every frame).
InstancedMesh: setColorAt() then instanceColor.needsUpdate = true; setMatrixAt() then instanceMatrix.needsUpdate = true. instanceColor is null until the first setColorAt, and any instance you never set renders WHITE -- set every instance.
Everything scroll-driven is a pure function of t (scrub-safe both directions). No time-accumulated state driving scroll visuals.
Semantic layer is the scroll-height authority -- when GL mounts it gets visibility:hidden
- inert, NEVER display:none (that collapses scroll height and breaks the scroll rig).
Accessibility while GL runs = the a11y overlay, not the canvas. Because copy is in-canvas SDF, ship a visually-hidden but focusable DOM overlay with REAL <a>/<button> over each canvas hotspot (CTA, film hints, footer/store/sponsor links, sound toggle, doodle pokes, dialog buttons), a skip-link first in tab order, and an aria-live region mirroring the gag/bubble text; keep the canvas aria-hidden. See webgl-standards. Never leave interactive controls canvas-only.
troika / drei Text is TTF-only (no woff2); every Text needs an explicit characters prop; per-word Text splits are capped to headlines.
ASCII-only source (Turbopack multi-byte sourcemap crash) -- non-ASCII copy lives \uXXXX-escaped in src/content/, never inline in a component.

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.

webgl-author is an agent published in the GitHub repository saeedkolivand/ai-job-hunter-app (54 stars, last pushed today), licensed Apache-2.0. It adds 103 tokens to every session and 1,019 once invoked, about $0.0005 per session on Opus 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.
