What it does

Image Gen is an agent skill from Sma1lboy/rove. Generate a single image from a text prompt using the MiniMax image generation API. Use when the user asks to create, generate, or render an image from a prompt and explicit width/height.

Its SKILL.md is about 930 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/image-gen.py`).

It sits in Media & Creative, covering Image generation. It works with MiniMax. The repository describes itself as: Rove — the agent multiplexer for your terminal. Run coding agents on parallel tasks with isolated worktrees and persistent sessions. The licence is MIT.

When your agent uses it

  • The user asks to create
  • Render an image from a prompt and explicit width/height

Example prompts

  • “/image-gen”

Requirements

  • Python 3

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Santorini paper-cut collage (UI style, non-photorealistic)
  2. Square UI icon (1:1)
  3. Landscape banner (16:9)
  4. Portrait poster (2:3)

What it can do on your machine

Read from SKILL.md and the folder at commit 139a8cb. 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

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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 Gen loads about 927 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 264 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~927

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); the scripts in this folder are not scanned.

Generate a single image from a text prompt using the MiniMax image generation API. Use when the user asks to create, generate, or render an image from a prompt and explicit width/height.

image-gen

Generate one image from a text prompt via MiniMax image-01 model. The output file is written to the filename you pass as the 4th argument (relative to the caller's cwd).

The script path is resolved relative to this SKILL.md (not the caller's cwd), so it works from any directory. It accepts exactly four positional arguments: prompt, width, height, output_filename.

bash
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
python3 "$SCRIPT_DIR/scripts/image-gen.py" "<prompt>" <width> <height> <output_filename>
ArgumentTypeConstraints
promptstring≤ 1500 chars; describe subject + style + mood
widthint512–2048, must be a multiple of 8
heightint512–2048, must be a multiple of 8
output_filenamestringFilename to write the image to, relative to cwd (e.g. img1.png). The file extension is preserved as-is.

Output

  • File: <output_filename> (relative to cwd — the directory the command is invoked from)
  • Format: raw image bytes base64-decoded from the API response; extension is whatever you pass (e.g. .png, .jpeg)
  • Always overwrites an existing file at the same path

After running, confirm the file exists with ls -lh <output_filename> and report the absolute path to the user.

Prompt writing tips

Be explicit about style to avoid photorealistic defaults. Example style keywords:

  • Flat / UI / vector: UI style, flat illustration, vector art, minimalist, clean cut-and-paste aesthetic, no photography no realistic textures
  • Collage / cut-and-paste: paper cut collage, layered flat cut-out shapes, torn paper edges, mixed media
  • Vintage / retro: vintage paper collage, sun-faded tones, retro travel poster
  • Photorealistic: photorealistic, documentary photography, film grain

Combine subject + style + palette. Example structure: "<style keywords>: <subject>, <key visual elements>, <color palette>, <negative constraints>"

Examples

1. Santorini paper-cut collage (UI style, non-photorealistic)
bash
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
python3 "$SCRIPT_DIR/scripts/image-gen.py" "UI style paper cut collage of Santorini, Greece: whitewashed houses with blue domes, ancient Greek columns, olive branches, terracotta rooftops, layered flat cut-out shapes with torn paper edges, clean vector illustration, minimalist cut-and-paste aesthetic, pastel color palette, no photography no realistic textures" 512 512 santorini.png
2. Square UI icon (1:1)
bash
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
python3 "$SCRIPT_DIR/scripts/image-gen.py" "flat vector icon of a paper airplane, minimal geometric shapes, soft blue and white palette, clean UI illustration, no shadows no gradients" 512 512 airplane.png
3. Landscape banner (16:9)
bash
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
python3 "$SCRIPT_DIR/scripts/image-gen.py" "minimalist flat illustration of mountains at sunset, layered geometric shapes, warm orange and purple palette, clean vector style, no texture no realism" 1280 720 mountains.png
4. Portrait poster (2:3)
bash
SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"
python3 "$SCRIPT_DIR/scripts/image-gen.py" "vintage paper collage portrait of a woman in 1920s fashion, torn paper layers, muted sepia and teal tones, art deco cut-out shapes, mixed media aesthetic" 832 1248 portrait.png

Can I use Image Gen in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Sma1lboy/rove --skill image-gen -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/image-gen, .gemini/skills/image-gen, .github/skills/image-gen and .opencode/skills/image-gen in your project.

What does Image Gen need to run?

Going by SKILL.md and its folder, Image Gen needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.

Does Image Gen access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Image Gen safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Image Gen use?

Image Gen is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Image Gen use?

About 927 tokens (SKILL.md is roughly 3.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
