pixel-art

pixel-art is a skill for Claude Code, Codex from kyh/vibedgames. It costs 190 tokens per session (5,853 once invoked), scanned A, original, MIT.

A workflow for generating 2D pixel-art game assets such as characters, sprite sheets, backgrounds, and cutout images. Pixel art uses deliberately placed square-colored pixels as its visual style.

In plain words
What is it for?
Use it to create character poses, sprite sheets, game backgrounds, transparent assets, and short animations for games.
Why use it?
It provides repeatable recipes for producing game-ready images while keeping the pixel grid and character identity consistent.

Written for no agent in particular: nothing here depends on one. Also seen: reads .claude/ paths.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./game-assets/.

SkillSpector: 3 findings, up to medium

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 →

    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
  • medium Rogue Agent · line 69
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
  • medium Agent Snooping · line 277
    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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

pixel-art scanned grade A with 1 finding 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 326 lines — stays where its author put it; the contents beside it link to each section on GitHub.

2D Game Assets

Requires the vg CLI (npm install -g vibedgames, or pnpm dogfood in this repo). The vibedgames server holds the API key; no per-machine setup.

Full pipeline for 2D pixel art game assets: character → sprite sheets → background removal → game background. Each recipe is independently invokable, run just the part you need.

Always use --json so output is machine-readable. Use --download to save files locally. Do not curl URLs manually, use the --download flag.

These recipes are the fast path — 4-frame 2×2 image sheets, great for a quick playable or near-static pose. For polished animation (attack arcs, walk/run cycles, hurt, death) use the animated-spritesheets skill: it generates one labeled pose-board image per action, slices it, and packs an engine-loadable spritesheet.png + manifest in one command, holding the character's identity consistent across the whole animation.

Craft rule (all paths): no baked shadows in the sprite. Prompt against cast/contact/ground shadows, base ellipses, and floor lines — the engine adds shadows at render time, and a baked-in shadow fights the engine's.

Craft rule: the uniform-pixel-grid rule applies to sprites and tiles only. FX, weather particles, and swung weapons may scale, rotate, and move sub-pixel — mixed pixel sizes on those layers read smoother, not wrong (every good pixel-art game cheats here). Don't pixel-snap particle/FX layers or force effects onto the sprite grid.


Execution rules, follow these strictly

  1. Each generation call = one Bash tool call: issue each vg generate run and vg generate status as its own bare tool call. No variable assignments, no pipes, no shell redirects. This keeps every call matching the vg generate * allowlist so it runs without permission prompts.

  2. Parallel jobs → async: issue each vg generate run --async as its own separate Bash tool call (not combined into one shell block). All jobs queue and run in parallel server-side; total time ≈ slowest single job. After all are fired, poll each with vg generate status sequentially (not in parallel, one failure must not cancel others).

pixel-art is a skill published in the GitHub repository kyh/vibedgames (55 stars, last pushed today), licensed MIT. It adds 190 tokens to every session and 5,853 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
