imagegen

imagegen is a skill for Codex from foryourhealth111-pixel/Vibe-Skills. It costs 74 tokens per session (2,206 once invoked), scanned A, a copy of imagegen, Apache-2.0.

A helper for generating or editing raster images through the OpenAI Image API. Raster images are pixel-based files such as photographs, illustrations, and mockups.

In plain words
What is it for?
Use it for concept art, website assets, product shots, UI mockups, logo ideas, transparent backgrounds, background changes, object removal, and batch image variants.
Why use it?
It provides a repeatable way to create, edit, and produce multiple image variants for a project.

About the project

Vibe-Skills is a collection and routing system that helps AI agents discover, select, and coordinate specialized skills for completing tasks. It is intended for agents that need to organize workflows across many installed capabilities. The catalogue entries are skills and an agent belonging to this system.

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

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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/image_gen.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Image Generation Skill

Generates or edits images for the current project (e.g., website assets, game assets, UI mockups, product mockups, wireframes, logo design, photorealistic images, infographics). Defaults to gpt-image-1.5 and the OpenAI Image API, and prefers the bundled CLI for deterministic, reproducible runs.

When to use

  • Generate a new image (concept art, product shot, cover, website hero)
  • Edit an existing image (inpainting, masked edits, lighting or weather transformations, background replacement, object removal, compositing, transparent background)
  • Batch runs (many prompts, or many variants across prompts)

Decision tree (generate vs edit vs batch)

  • If the user provides an input image (or says “edit/retouch/inpaint/mask/translate/localize/change only X”) → edit
  • Else if the user needs many different prompts/assets → generate-batch
  • Else → generate

Workflow

  1. Decide intent: generate vs edit vs batch (see decision tree above).
  2. Collect inputs up front: prompt(s), exact text (verbatim), constraints/avoid list, and any input image(s)/mask(s). For multi-image edits, label each input by index and role; for edits, list invariants explicitly.
  3. If batch: write a temporary JSONL under tmp/ (one job per line), run once, then delete the JSONL.
  4. Augment prompt into a short labeled spec (structure + constraints) without inventing new creative requirements.
  5. Run the bundled CLI (scripts/image_gen.py) with sensible defaults (see references/cli.md).
  6. For complex edits/generations, inspect outputs (open/view images) and validate: subject, style, composition, text accuracy, and invariants/avoid items.
  7. Iterate: make a single targeted change (prompt or mask), re-run, re-check.
  8. Save/return final outputs and note the final prompt + flags used.

Temp and output conventions

  • Use tmp/imagegen/ for intermediate files (for example JSONL batches); delete when done.
  • Write final artifacts under output/imagegen/ when working in this repo.
  • Use --out or --out-dir to control output paths; keep filenames stable and descriptive.

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.
