Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00095 | $0.02702 |
| Opus 5 | $0.00048 | $0.01351 |
| Sonnet 5 | $0.00019 | $0.00540 |
| Haiku 4.5 | $0.00010 | $0.00270 |
Grade A, and why
sprite-forge 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.
How it starts
The opening of the file, as written. The whole thing — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Sprite Forge
Generate game-ready sprites, SVG characters, ASCII art, animated mascots, and isometric turnarounds from images or text descriptions. Five output modes, each with proven pipelines.
When to Use
- Creating pixel-art characters or converting images to pixel art
- Generating sprite sheets with walk cycles, idle, attack animations
- Building 8-way isometric character turnarounds for tactics/RPG games
- Producing clean, hand-editable SVG characters or icons
- Converting images to ASCII/Unicode terminal art
- Animating mascots with GSAP walk, bounce, wave, or typing presets
- Generating lil-agents macOS dock companion videos
When not to use agents: Each pipeline is sequential — generate image, then process, then stitch. Work directly rather than spawning subagents, because intermediate outputs from one step feed the next. Parallel agents only help when generating multiple independent characters simultaneously.
Quick Start
# Isometric 8-way turnaround from a character image
python3 scripts/isometric_pipeline.py --reference character.png --output-dir ./iso/
# Video walk cycle → game sprite sheet with atlas
python3 scripts/video_to_spritesheet.py --input walk.mp4 --fps 12 --cell-size 64x64 --atlas json
# Image → pixel-art SVG mascot with walk animation
magick input.png -fuzz 15% -trim +repage /tmp/trimmed.png
python3 scripts/pixel_art_generator.py /tmp/trimmed.png --grid 20 --colors 4 --merge --remove-bg -o mascot.svg
python3 scripts/animation_builder.py --preset walk-and-bounce --svg-id mascot
# Image → terminal ASCII art
python3 scripts/image_to_ascii.py input.png --mode color --width 80
# Stitch frames into a sprite sheet with atlas
python3 scripts/stitch_spritesheet.py --input-dir frames/ --cols 8 --atlas json -o sheet.png
# Remove green screen background
python3 scripts/chroma_key.py --input sprite.png --output sprite_alpha.png --despill
Pipeline 1: Isometric Turnaround
Generate an 8-way directional character sprite from a single reference image. Based on chongdashu's FFT-style pipeline (github.com/chongdashu/vibe-isometric-sprites, Mar 2026).

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.
- 6d ago First seen · 221 lines · 95 tokens per session scan A 42b81e99f816
sprite-forge is a skill published in the GitHub repository tdimino/claude-code-minoan (41 stars, last pushed 2d ago), licensed MIT. It adds 95 tokens to every session and 2,702 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 2026-09-03.
