What is openai-image-gen-hardened?

A script that creates images through OpenAI's Images API from written prompts, including batches of varied prompts, and builds an HTML gallery of the results.

Use it to generate images from prompts, create batches, choose image models and sizes, request transparent backgrounds, and review results in a gallery.

It removes the need to write image-generation requests and manually assemble a page for reviewing many outputs.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/faberlens/hardened-skills

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.

Model	Per session	Once invoked
Fable 5.1	$0.00028	$0.01056
Opus 5.5	$0.00011	$0.00422
Sonnet 5.5	$0.00006	$0.00211
Haiku 4.5	$0.00003	$0.00106

Security

Grade A, and why

openai-image-gen-hardened 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 1mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenAI Image Gen

Generate a handful of “random but structured” prompts and render them via the OpenAI Images API.

Run

python3 {baseDir}/scripts/gen.py
open ~/Projects/tmp/openai-image-gen-*/index.html  # if ~/Projects/tmp exists; else ./tmp/...

Useful flags:

# GPT image models with various options
python3 {baseDir}/scripts/gen.py --count 16 --model gpt-image-1
python3 {baseDir}/scripts/gen.py --prompt "ultra-detailed studio photo of a lobster astronaut" --count 4
python3 {baseDir}/scripts/gen.py --size 1536x1024 --quality high --out-dir ./out/images
python3 {baseDir}/scripts/gen.py --model gpt-image-1.5 --background transparent --output-format webp

# DALL-E 3 (note: count is automatically limited to 1)
python3 {baseDir}/scripts/gen.py --model dall-e-3 --quality hd --size 1792x1024 --style vivid
python3 {baseDir}/scripts/gen.py --model dall-e-3 --style natural --prompt "serene mountain landscape"

# DALL-E 2
python3 {baseDir}/scripts/gen.py --model dall-e-2 --size 512x512 --count 4

Model-Specific Parameters

Different models support different parameter values. The script automatically selects appropriate defaults based on the model.

Size

GPT image models (gpt-image-1, gpt-image-1-mini, gpt-image-1.5): 1024x1024, 1536x1024 (landscape), 1024x1536 (portrait), or auto
- Default: 1024x1024
dall-e-3: 1024x1024, 1792x1024, or 1024x1792
- Default: 1024x1024
dall-e-2: 256x256, 512x512, or 1024x1024
- Default: 1024x1024

Quality

GPT image models: auto, high, medium, or low
- Default: high
dall-e-3: hd or standard
- Default: standard
dall-e-2: standard only
- Default: standard

Other Notable Differences

dall-e-3 only supports generating 1 image at a time (n=1). The script automatically limits count to 1 when using this model.
GPT image models support additional parameters:
- --background: transparent, opaque, or auto (default)
- --output-format: png (default), jpeg, or webp
- Note: stream and moderation are available via API but not yet implemented in this script
dall-e-3 has a --style parameter: vivid (hyper-real, dramatic) or natural (more natural looking)

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

openai-image-gen-hardened is a skill published in the GitHub repository faberlens/hardened-skills (25 stars, last pushed 6mo ago), licensed MIT. It adds 28 tokens to every session and 1,056 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
