Agent Sprite Forge is a Codex-oriented workflow for producing reusable 2D game assets such as sprite sheets, map layers, transparent PNG frames, and animated GIFs. It supports game developers working with Godot, Unity, or other 2D workflows by combining image generation with local processing, asset validation, and engine-ready exports, and its catalogue skills provide the workflow.
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.

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 | $0.00124 | $0.02233 |
| Opus 5 | $0.00062 | $0.01117 |
| Sonnet 5 | $0.00025 | $0.00447 |
| Haiku 4.5 | $0.00012 | $0.00223 |
Grade A, and why
video2dsprite 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 8d 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 — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Video2dsprite (Grok Build only)
Convert a base 2D character image into dense animation sprites using Grok Build's native video tools.
base still → image_to_video (in-place motion) → extract frames → chroma key → sample/normalize → strip / grid / GIF
Platform gate (read first)
| Runtime | Supported? |
|---|---|
| Grok Build (xAI) | Yes — requires image_gen / image_edit + image_to_video (or reference_to_video) |
| Codex / Claude / other agents | No — they lack Grok video tools. Tell the user this skill is Grok Build only and offer $generate2dsprite instead |
If image_to_video is missing from the tool list, stop and explain. Do not fake motion with code-drawn frames.
This skill is an optional denser-motion path. It does not replace $generate2dsprite:
Use $generate2dsprite when… |
Use $video2dsprite when… |
|---|---|
| Crisp pixel sheets, fixed grids, identity-critical heroes | User wants denser intermediate poses / smoother feeling loops |
| Attack/cast body sheets, prop packs, engine atlases | Experimenting with video-sourced run/walk/idle motion |
| Production default for most game sprites | User explicitly asks for video → frames → sprites |
Video softens pixels, drifts identity, and leaves chroma fringes. Always QC; for production heroes, prefer $generate2dsprite unless the user wants the video look.

What ships with it
4 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.

video2dsprite is a skill published in the GitHub repository 0x0funky/agent-sprite-forge (4,026 stars, last pushed 1mo ago), licensed MIT. It adds 124 tokens to every session and 2,233 once invoked, about $0.0006 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 2026-08-30.
