What it does

Agnes Free Image is an agent skill from kangarooking/agnes-free-model-skills. Generate free images with Agnes Image 2.1 Flash through the Agnes API, including text-to-image, image-to-image, high-density visual prompts, URL results, and local downloads. Use when the user asks for 免费图片, 免费的图片模型, free image API, Agnes image, Agnes Image 2.1 Flash, free AI image generation, image-to-image via Agnes, or wants a free image model Agent skill.

Its SKILL.md is about 690 tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/api.md` and `scripts/agnes_image.py`).

It sits in Media & Creative, covering Image generation. The repository describes itself as: Agnes AI 免费文本、图片、视频模型的 Codex/Agent Skills. The licence is MIT.

When your agent uses it

The user asks for 免费图片
Agnes Image 2.1 Flash
Free AI image generation
Image-to-image via Agnes

Example prompts

“/agnes-free-image”

Requirements

Python 3
A credential in AGNES_API_KEY
A credential in AGNES_TOKEN

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

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-run first for complex prompts or reference images.
Save returned image URLs locally with --output-dir when the response includes downloadable URLs.
Read references/api.md when the raw response shape or advanced parameters matter.

What it can do on your machine

Read from SKILL.md and the folder at commit f5cb579. 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
Hosts in commands or code, which the agent is likely to contact:
- apihub.agnes-ai.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- AGNES_TOKEN
- AGNES_API_KEY
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Agnes Free Image loads about 687 tokens when it runs, and up to ~1.4k if it reads all its reference files. Until then it costs about 95 tokens; SKILL.md has 199 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~95
When it runs · the whole SKILL.md, loaded when a task matches: ~687
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~1.4k

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.

description: Generate free images with Agnes Image 2.1 Flash through the Agnes API, including text-to-image, image-to-image, high-density visual prompts, URL results, and local downloads. Use when the user asks for 免费图片, 免费的图片模型, free image API, Agnes image, Agnes Image 2.1 Flash, free AI image generation, image-to-image via Agnes, or wants a free image model Agent skill.

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:

bash

export AGNES_API_KEY="..."

The helper also accepts AGNES_TOKEN as a fallback.

Quick Start

Text-to-image:

bash

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:

bash

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:

bash

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:

text

[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-run first for complex prompts or reference images.
Save returned image URLs locally with --output-dir when the response includes downloadable URLs.
Read references/api.md when 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".

Reference

Read references/api.md when you need request fields, response handling, or prompt examples from the source docs.
