hashiiiii-images

hashiiiii-images is a skill for Claude Code from hashiiiii/rules-for-ai. It costs 26 tokens per session (887 once invoked), scanned A, original, MIT.

A set of instructions for creating project images, including logos, icons, favicons, promotional tiles, and README header images. It covers both simple vector designs and more illustrative raster images.

In plain words
What is it for?
Use it when a project needs a flat geometric graphic with a dark background and one accent color, or when it needs an illustrative image with a removed background.
Why use it?
It helps decide what kind of image to make and gathers the requirements needed before drawing. This avoids producing artwork with the wrong size, background, or color.

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

hashiiiii-images 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 11d 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.

Images

First, select vector or raster output. If words fully describe the image, write SVG code with the procedure below.

Do not make a flat geometric image as a raster image.

The process controls the image quality. Limit the design language. Then compare candidates at their target sizes before you select one.

When to Use

  • Use this skill for logo marks, icons, favicons, promo tiles, and README header images.
  • Use this skill for an OSS style with two to four shapes and one accent color.

If the image is illustrative or photorealistic, use a raster image generator. Then use a process that removes the background.

Gather Requirements First

Collect four inputs before you create an image. The request and the repository can already contain some inputs.

For each missing input, ask the user. Ask one question at a time. Include the default in each question.

Do not draw until you know all four inputs. A temporary accent or an exploratory draft still uses assumptions.

An incorrect background or color invalidates the complete contact sheet. One early question prevents work on incorrect candidates.

Input Confirm Default to offer
Target Identify the asset and its smallest usable size. If the request does not specify a target, always ask.
Colors Identify the accent color and the intended background. Use a dark background and one accent color.
Motif Identify the name meaning, domain concepts, and motifs to avoid. Use the project name and README.
Output Identify the file formats and target paths. Create an SVG mark and PNG files at the target sizes.

The target supplies the sizes for step 3. The motif supplies the metaphor list for step 2.

The Recipe

  1. Define the design language. Use two to four basic shapes for each mark. Use one accent color for each mark. Prefer negative space to additional detail. Do not use gradients or text.
  2. List metaphors. Write at least four visual metaphors from the project domain. Include the name meaning and the tool function. Give one metaphor to each candidate.
  3. Create a contact sheet. Put four to six candidate tiles in one SVG. Show each candidate at approximately 100 px. Also show it at its smallest target size. Use the intended background color. Render the SVG. Then inspect the PNG at its actual sizes.
  4. Select one candidate. Refine it with coordinate changes. If no candidate works, change the constraints. Then create a new contact sheet. Do not refine a weak candidate.
  5. Deliver only the foreground mark. Do not put a background tile in the final SVG. The context supplies the background. Use fill-rule="evenodd" subpaths for transparent holes. Do not use shapes that have the background color.
