What it does

Image Prompt is an agent skill from davidondrej/skills. Write four distinct prompts for AI image models. Use for image, thumbnail, banner, logo, or illustration prompts. Produces prompt text only.

Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Diffusion and image models. The repository describes itself as: access to david ondrej's personal agent skills. The licence is MIT.

When your agent uses it

  • Illustration prompts
  • Tasks that involve Diffusion and image models

Example prompts

  • “/image-prompt”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Blank line after the label
  2. Opening fence on its own line: three backticks then text
  3. The prompt paragraph
  4. Closing fence on its own line

What it can do on your machine

Read from SKILL.md and the folder at commit 7874889. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Image Prompt loads about 659 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 325 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~659

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Write four distinct prompts for AI image models. Use for image, thumbnail, banner, logo, or illustration prompts. Produces prompt text only.

Image Prompt

Write 4 model-agnostic prompt variations that the user can paste into any image model.

Output format

  • Exactly 4 variations, each one paragraph in its own fenced code block. Nothing else inside.
  • Always use a text fence so it renders as a full copyable block, not a tiny snippet. Pattern:
    1. Blank line after the label
    2. Opening fence on its own line: three backticks then text
    3. The prompt paragraph
    4. Closing fence on its own line
  • Never wrap a prompt in single backticks. Never use a bare unlabeled fence. Those render as small snippets and are hard to copy.
  • Every prompt ends with --ar 1:1. It is the Midjourney aspect-ratio flag and is harmless in other models. If the user names an aspect ratio, use that instead (e.g. --ar 16:9).
  • A 3-5 word label above each block is fine. No commentary, no explanations, no questions after.

How to write each prompt

Describe a finished piece in clear, expressive, descriptive prose. Each paragraph covers:

  1. Subject — what it is, what it is doing, the defining details.
  2. Environment — where it sits, background, lighting, time of day.
  3. Color palette — name the dominant colors and the contrast.
  4. Vibe and feeling — the mood and the emotion the image should evoke.
  5. Style / medium — photograph, cinematic still, 3D render, oil painting, flat vector, etc.

Rules

  • Descriptive prose only. No bullet lists inside a prompt, no "imagine a...", no "create an image of".
  • Make the 4 variations genuinely different — different style, composition, mood, or palette. Not rewordings of one idea.
  • No text inside the image unless the user asks; models render text badly.
  • No negative prompts and no model-specific parameters other than --ar.
  • If the request is vague, still deliver 4 prompts. Pick sensible defaults, do not ask questions.

Example

Request: "logo concept for Vectal Labs, something about invention"

Filament in the void

text
A single glowing filament bulb suspended in a vast dark void, its wire coiled into a rising spiral, casting warm amber light onto faint blueprint lines etched into black glass beneath it. Deep charcoal and midnight blue with one accent of molten gold. Quiet and reverent, the feeling of a first idea arriving at 3 a.m. Minimal, high contrast, rendered like a luxury product photograph. --ar 1:1

(…then three more, each in its own code block, each a different direction.)
