An image-generation tool that sends prompts to several AI image services, including Codex, Antigravity, and Pollinations. It handles authentication-aware routing, reference images, cost controls, and output records.

Use it to create illustrations, product images, concept art, mockups, and other visual assets from prompts, including comparisons across image models.

It gives image-generation workflows one place to choose or compare supported image services.

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	$0.00085	$0.03578
Opus 5.5	$0.00034	$0.01431
Sonnet 5.5	$0.00017	$0.00716

Security

Grade A, and why

oma-image 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.

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.

Origin

This is a copy

Image Agent - Multi-Vendor Image Router

Scheduling

Goal

Generate images and visual assets through authenticated multi-vendor routing while preserving prompt clarity, reference-image handling, cost controls, and reproducible output manifests.

Intent signature

User asks to generate images, visual assets, illustrations, product photos, concept art, mockups, or AI art.
Another skill needs shared image-generation infrastructure.
User provides reference images or asks for vendor comparison.

When to use

Generating images, visual assets, illustrations, product photos, concept art
Comparing output between multiple image models for the same prompt
Producing images from prompts within editor workflows (Claude Code, Codex, Gemini CLI)
Other skills needing image generation infrastructure (shared invocation)

When NOT to use

Editing an existing image or photo manipulation -> out of scope
Generating videos or audio -> out of scope
Inline vector art / SVG composition from structured data -> use a templating skill
Simple asset resizing or format conversion -> use a dedicated image library

Expected inputs

Image prompt or creative brief
Optional vendor, size, quality, count, output directory, and reference images
Authentication/environment state for Codex, Pollinations, or Gemini

Expected outputs

Generated image files under .agents/results/images/ or requested output directory
manifest.json with prompt, vendor, model, and reproducibility metadata
Vendor comparison outputs when --vendor all is used

Dependencies

oma image generate CLI and vendor authentication
Codex image generation, Pollinations API, or Gemini API/CLI strategy
resources/vendor-matrix.md, resources/prompt-tips.md, and config/image-config.yaml

Control-flow features

Branches by prompt ambiguity, vendor auth, cost threshold, reference-image support, path safety, and safety/timeout exit codes
Calls external vendor APIs/CLIs
Reads reference images and writes generated images plus manifests

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.
