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 | $0.00124 | $0.00654 |
| Opus 5 | $0.00062 | $0.00327 |
| Sonnet 5 | $0.00025 | $0.00131 |
| Haiku 4.5 | $0.00012 | $0.00065 |
Grade A, and why
add-shader-cursor-trail 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 6d 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.
This is a copy
100% identical to add-shader-cursor-trail — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 35 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Shader Cursor Trail
Implement the exact trail as progressive enhancement. Preserve the host section's semantic content, imagery, controls, and static first frame.
Workflow
- Inspect the framework, rendering mode, existing motion stack, layer order, reduced-motion rules, and package manager. Do not add another smooth-scroll engine or replace the section's content.
- Install
shaderswith the existing package manager. Import from the matching framework subpath:shaders/react,shaders/vue,shaders/svelte, orshaders/solid. - Read references/implementation.md before implementation. Keep the six shader nodes, their order, both invisible drivers, and both ID linkages exact.
- For React or Next.js, copy and adapt the files in
assets/react/. Keep the lightweight capability gate separate from the heavy shader module so ineligible visitors do not request the shader bundle. - Place one full-bleed,
aria-hidden="true"shader layer behind the section content. Keep links and controls above it. Do not setpointer-events: noneon the canvas unless cursor tracking is verified to use global events. - Gate loading on WebGPU, a fine hover pointer, normal motion/transparency preferences, document visibility, window focus, and section intersection. Unmount when the section leaves view so GPU work stops.
- Keep the original image or dark background as the complete fallback. Hide the layer for reduced motion, reduced transparency, coarse/no-hover pointers, and forced colors.
- Adapt only presentation variables such as opacity and blend mode. Do not change the graph to decorative noise, add WebGL/Three.js, or hotlink Shaders preview assets.
Validate
Run the project's lint, typecheck/tests, and production build. For React implementations, also run:
node /path/to/add-shader-cursor-trail/scripts/verify-cursor-trail.mjs \
path/to/CursorTrailShader.tsx \
path/to/CursorTrailGate.tsx \
path/to/cursor-trail.css
What ships with it
6 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.

add-shader-cursor-trail is a skill published in the GitHub repository 2233admin/design-pipeline (9 stars, last pushed 7d ago), licensed MIT. It adds 124 tokens to every session and 654 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to add-shader-cursor-trail, differing in 0 lines, and is treated as a copy.
