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 | $0.00050 | $0.01163 |
| Opus 5 | $0.00025 | $0.00581 |
| Sonnet 5 | $0.00010 | $0.00233 |
| Haiku 4.5 | $0.00005 | $0.00116 |
Grade A, and why
minecraft-imagegen 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 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.
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.

Minecraft Image Generation Skill
Use this skill when a Minecraft project needs new raster art or a visual concept that will later be refined into a resource pack, release post, store listing, or server brand asset.
Scope
Routing Boundaries
Use when: the task is generating or editing a bitmap image for a Minecraft project, such aspack.png, release art, store thumbnails, concept textures, UI mockups, or server/banner art.Do not use when: the task is deterministic resource-pack implementation work such aspack.mcmeta, block/item model JSON, blockstates, fonts, sounds, or shader files (minecraft-resource-pack).Do not use when: the task is vector/code-native UI, an existing SVG/logo system, or non-image code/assets.Do not use when: the current host does not expose built-in image generation or an equivalent image-editing tool.
Support Assets
- Read prompt patterns for an underspecified request or a generation/edit prompt template.
- Read asset recipes for a pack icon, release banner, server header, or texture concept sheet.
- Use
scripts/scaffold-asset-brief.shonly when a saved brief is useful for stakeholder feedback or repeated rounds; a clear image request can proceed directly. - Invoke the helper by its absolute installed path from the project workspace. Relative
--outvalues resolve from that workspace. When running from the installed skill directory, pass an absolute--outproject path or setCODEX_WORKSPACE_ROOT.
Default Execution
- If the current host does not expose built-in image generation or an equivalent image-editing tool, stop and tell the user this skill is unavailable on that host; offer prompt/brief preparation or a host with an available image-generation tool.
- Use the built-in
image_gentool by default when the host supports it. - Match the requested deliverable: complete a requested asset, or produce concepts when the user asks for exploration. Do not require a separate concept approval for a clear generation or edit request.
- The built-in image generation workflow supports fresh generations and edits against existing local/reference images; prefer that over describing a manual paint-over process.
- Save a requested project asset at the intended workspace path when the host exposes the output file; otherwise return the generated image and state that a local save could not be verified.
- Preserve existing assets non-destructively by using versioned filenames unless the user explicitly asked to overwrite.
- If editing a local image, load or attach it first so the image is visible to the agent before requesting an edit.
What ships with it
3 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.

minecraft-imagegen is a skill published in the GitHub repository Jahrome907/minecraft-agent-skills (136 stars, last pushed 5d ago), licensed MIT. It adds 50 tokens to every session and 1,163 once invoked, about $0.0003 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.
