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

generate2dsprite 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/generate2dsprite.py, scripts/make_layout_guide.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Generate2dsprite

Use this skill for self-contained 2D sprite or animation assets in the app-builder sandbox (TanStack Start + browser games).

When a larger game or playable prototype needs sprites, use this skill for the visible sprite assets and keep runtime/game assembly separate (wire into Phaser / Canvas / DOM after export). Do not replace requested sprite assets with code-drawn placeholders.

App-builder / Grok environment

Item Value
Skill dir .grok/skills/generate2dsprite/
Scripts python3 .grok/skills/generate2dsprite/scripts/<script>.py …
Image tools imagine_text_to_image / imagine_image_to_image (path-based; see imagine skill for prompt craft)
Inspect images read_file on the PNG path (not Codex view_image)
Generated image path imagine_text_to_image returns a sandbox file_path; copy that path into your run dir before processing
Python deps Pillow + numpy (preinstalled in the image)
Output home Prefer assets/sprites/<name>/ under /workspace so the app can import them
Engine target Browser: Canvas 2D, Phaser, or DOM/<img> — not Godot/Unity unless the user asks

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.
