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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00090 | $0.00654 |
| Opus 5 | $0.00045 | $0.00327 |
| Sonnet 5 | $0.00018 | $0.00131 |
| Haiku 4.5 | $0.00009 | $0.00065 |
Grade A, and why
agnes-free-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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agnes Free Image
Use this skill to generate or transform images with agnes-image-2.1-flash.
Credential Rule
Read the API key from the environment. Do not hardcode keys in prompts, scripts, skill files, commits, or shell history.
Preferred variable:
export AGNES_API_KEY="..."
The helper also accepts AGNES_TOKEN as a fallback.
Quick Start
Text-to-image:
python3 scripts/agnes_image.py generate \
--prompt "A luminous floating city above a misty canyon at sunrise, cinematic realism" \
--size 1024x768 \
--output-dir ./outputs/agnes-free-image
Image-to-image with a public image URL:
python3 scripts/agnes_image.py generate \
--prompt "Transform the scene into a rain-soaked cyberpunk night while preserving the composition" \
--image-url "https://example.com/input.png" \
--size 1024x768 \
--output-dir ./outputs/agnes-free-image
Validate the request shape without calling the API:
python3 scripts/agnes_image.py generate \
--prompt "A detailed AI workflow dashboard poster, clean editorial style" \
--size 1024x1024 \
--dry-run
Prompt Pattern
Use this structure for text-to-image:
[Subject] + [Scene / Environment] + [Style] + [Lighting] + [Composition] + [Quality Requirements]
For image-to-image, say both what should change and what should remain unchanged.
Workflow
- Decide whether the request is text-to-image or image-to-image.
- Turn vague visual requests into a concrete prompt with subject, environment, style, lighting, composition, and detail level.
- Use
scripts/agnes_image.py generate. Prefer--dry-runfirst for complex prompts or reference images. - Save returned image URLs locally with
--output-dirwhen the response includes downloadable URLs. - Read
references/api.mdwhen the raw response shape or advanced parameters matter.
Notes
- Endpoint:
POST https://apihub.agnes-ai.com/v1/images/generations - Model:
agnes-image-2.1-flash - Default size in the helper is
1024x768. - For image-to-image, input images must be URL-accessible and are sent under
extra_body.image. - The helper asks for URL responses with
extra_body.response_format: "url".
What ships with it
3 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.
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.
