.claude/skills/ascii-animation/SKILL.md

ascii-animation is a skill for Claude Code from ideoshi/glyphloop. It costs 51 tokens per session (368 once invoked), scanned A, original, MIT.

A tool for creating loop-perfect animations made from text characters, known as ASCII art, for websites or terminals.

In plain words
What is it for?
Use it to create web embeds, terminal animations, or raw frames from supported sources such as waves, rain, blobs, and 3D shapes.
Why use it?
It provides a repeatable way to define, render, and verify animated text-based visuals.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions AGENTS.md.

This is ideoshi/glyphloop's own configuration. It tells Claude Code how to work on glyphloop itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything glyphloop configures →

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

ascii-animation 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.

What it actually says

Generating ASCII animations

  1. Read AGENTS.md for the preset schema and per-source parameter tables.

  2. Author a preset - start from a file in presets/ and change only what the request needs (source, colors, size, duration, seed).

  3. Render headless:

    npm run render -- --preset <preset.json> --out <dir>            # web embed
npm run render -- --json '<inline-json>' --out <dir> --format terminal

  4. The command prints a JSON summary. On error: output, the message lists valid options - fix the preset and retry.

  5. For websites, deliver frames.json + player.js and this snippet:

    <div data-ascii-player></div>
<script>window.ASCII_DATA = /* frames.json contents */;</script>
<script src="player.js"></script>

Headless sources: flowfield, waves, blobs, rain, shapes3d, expr (custom brightness expression), parametric3d (custom 3D surface). Image/video/text base layers, color inheritance, and PNG/GIF/MP4 export need the editor UI (npm run dev, port 5199). Iterate on look by changing seed first, then params. Verify output by serving the out dir and checking the demo index.html.

Changes

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.
