background-grid-webgl

background-grid-webgl is a skill for Claude Code, Codex from devinilabs/pro-skill. It costs 30 tokens per session (518 once invoked), scanned A, a copy of background-grid-webgl, MIT.

A skill for creating a moving perspective grid in a web page using WebGL, the browser technology for rendering graphics with the graphics processor.

In plain words
What is it for?
Use it for a dark ground-plane grid with fading lines, drifting particles, subtle glow, and gentle camera movement.
Why use it?
It adds depth and a restrained technical atmosphere without requiring a flat static background.

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.

Security

Grade A, and why

background-grid-webgl 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 3d 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.

Background Grid WebGL Skill

Use When

  • Create a perspective WebGL background grid with fading lines, subtle particle haze, slow forward drift, and gentle camera parallax.

Workflow

Scope

  • Apply this only to the immersive background grid layer, not to the full page layout, copy, or unrelated particle or laser systems.
  • Use it when the design needs a perspective tech grid receding into space with subtle motion and depth.

Visual target

  • Create a large perspective ground-plane grid viewed from an elevated camera angle so the lines recede toward the horizon.
  • Keep the grid understated and atmospheric: thin lines, soft fade with distance, dark background, and restrained glow rather than a loud retro neon floor.
  • Add a light field of floating particles or dust to give the scene depth without overpowering the grid.
  • Use the design's primary color or strongest accent color sparingly for glow, particles, or secondary emphasis. If the design is neutral, a white or cool gray grid is acceptable.

Implementation guidance

  • Prefer Three.js or equivalent real WebGL rendering for this effect.
  • Use a perspective camera positioned above the plane and looking toward the origin to emphasize depth.
  • Build the grid as a large plane helper or custom grid with line opacity fading by distance so the far field dissolves smoothly.
  • Animate the grid with slow forward drift or repeated positional cycling so it feels alive without becoming distracting.
  • Add subtle mouse-responsive camera parallax or offset, but keep the movement calm and damped.
  • Add a sparse additive particle field with low opacity and slow motion to soften the empty space around the grid.

Tuning knobs

  • Grid density: control plane size, division count, and line spacing.
  • Fade: adjust opacity falloff so the grid recedes naturally into darkness.
  • Motion: tune forward drift speed, particle float speed, and camera smoothing.
  • Camera: adjust height, distance, tilt, and parallax strength to control perspective drama.
  • Color: keep the base grid subtle and use the active design accent only as a restrained highlight.
