What it does

Cf Image is an agent skill from hassancs91/claude-image-generation. Generate an image from a text description using Cloudflare Workers AI (the flux-1-schnell model). Use this skill whenever the user wants to create, generate, make, or draw an image / picture / logo / icon / thumbnail / wallpaper / banner from a text idea and mentions Cloudflare, or is working in this repo and asks for a quick generated image. Claude expands the user's request into a strong image prompt, runs the bundled generate.py, and saves a JPG to disk. Trigger on phrases like "generate an image of", "make me…

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `generate.py`).

It sits in Media & Creative, covering Image generation and Diffusion and image models. It works with Cloudflare and Workers AI. The repository describes itself as: Connect Claude to image generation with Agent Skills. Three levels: a zero-cost code-based design engine, a Three.js 3D renderer, and a real diffusion model on Cloudflare. Plus… The licence is MIT.

When your agent uses it

  • The user wants to create
  • Draw an image / picture / logo / icon / thumbnail / wallpaper / banner from a text idea and mentions Cloudflare
  • Is working in this repo and asks for a quick generated image
  • Phrases like generate an image of

Example prompts

  • “generate an image of”
  • “make me a picture of”
  • “create a thumbnail for”
  • “/cf-image”

Requirements

  • Python 3
  • A credential in CF_API_TOKEN

Workflow steps

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

  1. Confirm the file was saved (the script prints the path).
  2. Tell the user the filename and the exact prompt you used, so they can tweak and re-run.
  3. If they want variations, re-run with a modified prompt and a new -o filename.

What it can do on your machine

Read from SKILL.md and the folder at commit f533831. 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 script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • CF_API_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cf Image loads about 867 tokens when it runs. Until then it costs about 178 tokens; SKILL.md has 385 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~178
When it runs · the whole SKILL.md, loaded when a task matches
~867

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:3
    UNT_ID and CF_API_TOKEN in the project's .env.
  • NoteMentions a .env fileSKILL.md:54
    and `CF_API_TOKEN` set in the project's `.env` (see `.env.example`). The script loads them automatically.

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); files beside SKILL.md are not scanned.

description
Generate an image from a text description using Cloudflare Workers AI (the flux-1-schnell model). Use this skill whenever the user wants to create, generate, make, or draw an image / picture / logo / icon / thumbnail / wallpaper / banner from a text idea and mentions Cloudflare, or is working in this repo and asks for a quick generated image. Claude expands the user's request into a strong image prompt, runs the bundled generate.py, and saves a JPG to disk. Trigger on phrases like "generate an image of", "make me a picture of", "create a thumbnail for", "cloudflare image", or a plain description paired with a request for an image. Requires CF_ACCOUNT_ID and CF_API_TOKEN in the project's .env.

cf-image

Turn a natural-language request into a generated image using Cloudflare Workers AI (@cf/black-forest-labs/flux-1-schnell). This skill is the "connect Claude to image generation" loop: the user describes what they want, Claude does the prompt engineering, the bundled script calls the Cloudflare API, and the image is saved locally.

When this skill applies

The user wants an image generated from a description — e.g. "generate a logo idea for a coffee shop", "make a thumbnail for my AI video", "picture of a cyberpunk cat". Claude is responsible for turning a vague ask into a good prompt before generating.

It does not apply to: editing an existing image, vector/SVG art, or video.

How to run it

From the repo root:

bash
python .claude/skills/level-3-image-generator/generate.py "<optimized prompt>" -o <filename>.jpg
  • "<optimized prompt>" — the prompt you write (see below), not the user's raw words.
  • -o / --output — where to save (default out.jpg). Pick a short descriptive name, e.g. coffee-logo.jpg.
  • --steps — diffusion steps (default 4). flux-schnell is tuned for few steps; 4–8 is plenty. Higher is slower, not always better.

The script prints Saved <file> ... on success, or a Cloudflare API error message on failure.

The one job Claude must do: write a strong prompt

The raw script would need a hand-written prompt. The value of this skill is that Claude expands the user's intent into a vivid, specific prompt before calling the script. A good Flux prompt names:

  • Subject — what's in the frame, concretely.
  • Style/medium — photo, 3D render, flat vector, watercolor, isometric, etc.
  • Composition & framing — close-up, wide shot, centered, rule-of-thirds.
  • Lighting & mood — golden hour, neon, soft studio light, dramatic shadows.
  • Color/detail cues — palette, background, level of detail.

Example transformation:

  • User: "a logo for a coffee shop"
  • Prompt you pass: "minimalist logo of a steaming coffee cup, flat vector illustration, warm brown and cream palette, centered on a clean off-white background, simple bold shapes, modern branding"

Keep prompts to one or two sentences. Don't include text/words to render — Flux is unreliable at rendering legible text.

After generating

  1. Confirm the file was saved (the script prints the path).
  2. Tell the user the filename and the exact prompt you used, so they can tweak and re-run.
  3. If they want variations, re-run with a modified prompt and a new -o filename.

Requirements

  • CF_ACCOUNT_ID and CF_API_TOKEN set in the project's .env (see .env.example). The script loads them automatically.
  • Python deps: requests, python-dotenv.
