Good fit
You want a set of pixel props for a game world that look like they belong together, you use an agent with an image tool, and you want a repeatable method instead of one-off prompts.

What you get
The download is the skill itself, ready to hand to your agent:
- SKILL.md: the method, start to finish
- skill.yaml: skill metadata
- references/prop-guide.md: the family guide template
- references/prompt-templates.md: the locked block and prompts
- references/consistency-checklist.md: the trait-by-trait and set audit
- references/pixel-spec.md: the pixel discipline rules
Sprites ship at your chosen canvas size, 16 to 128 pixels, with integer-multiple enlargements.
How it works
-
Lock the family guide first
Fill in one family guide: a silhouette sentence per prop, a palette of at most 16 colors plus outline, a scale ladder in fractions of character height, shared and distinct materials, and the outline, shading, and background rules. The forest set, for example, runs from a grass tuft at ankle height to a fence post at character height, all on one palette.
-
Generate drafts and assemble the reference board
Generate one draft per member on a plain white background. Then assemble the board from the drafts, never generate it as one image: every member stands in a row on a shared baseline at its ladder height, next to a marker bar exactly one character height tall and a row of palette swatches. Judge the board from the assembly log. Never assemble from a failing draft.
Forest set reference board, all 21 members. -
Generate props one at a time
Pass the board as reference on every call, paste the locked block verbatim, and generate exactly one prop: feet on the shared baseline, height equal to its ladder rung, materials colored only from the guide palette.
Fence post, one prop from the board. -
Audit every prop and the set, then export
Score silhouette, palette, height, baseline, shared materials, and pixel discipline separately for each prop, then audit the set as a whole: shared materials actually shared, outline and shading consistent, and the ladder actually holding. A prop passes only when every trait passes. Export at the canvas size with nearest neighbor, board at display size.
Rock, one prop from the board.
Good fit and not for
Not for
Tilesets, scenes, multi-prop dioramas, and animation frames are out of scope. A seamless grass tile is out: a tile must repeat without a visible edge, and that is a different problem with its own rules. And if you need guaranteed transparency, this is not it: transparency depends on the tool.
Requirements
Any agent plus an image tool that accepts reference images. No tool lock-in: the skill is written tool-agnostic, and the text-only fallback (locked block plus seed) is audited twice as strictly. You need no account and no payment to download it.
Example request
Ask your agent in plain words, for example: "Make me a forest set for a pixel game: a grass tuft at ankle height, a rock at knee height, and a fence post as tall as a character, all sharing one palette. Then put them on one board at relative scale." The skill turns that into a guide, a board, and audited props.

FAQ
Does it make tilesets?
No. Standalone props and small families only. A seamless grass tile is out of scope for version 1.
Does it make scenes?
No. One family per run, single props only. Multi-prop dioramas are out of scope.
Will my sprites be transparent?
It depends on your image tool. The skill never promises transparency before generating. It records which outcome the tool produced in the guide, and the fallback is one solid color.
What happens when a draft or prop fails?
The retry ladder runs: a draft retries at most three times (restate, rephrase, simplify), then stops and reports which trait will not hold. A prop retries at most three times. A failing sprite is never presented as passing.
What sizes can props be?
Canvas sizes run 16 to 128 pixels per side. Each prop gets the smallest canvas that fits its ladder height plus margins. The demo family runs from ankle height to character height.
Does consistency hold at 20 or more props?
Yes. The demo family has 21 validated members on one palette. The skill carries a member roster so no silhouette repeats, reuses palette materials instead of inventing colors, and re-checks the whole set as the family grows, so later props are held to the same traits as the first ones.
Does it copy an existing design?
No. You describe the family you want, and the skill builds it from your description. It does not clone an uploaded image.
