Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00156 | $0.00819 |
| Opus 5 | $0.00078 | $0.00409 |
| Sonnet 5 | $0.00031 | $0.00164 |
| Haiku 4.5 | $0.00016 | $0.00082 |
Grade A, and why
cf-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 11d 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 — 56 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
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 (defaultout.jpg). Pick a short descriptive name, e.g.coffee-logo.jpg.--steps— diffusion steps (default4). 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"
What ships with it
1 file 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.

cf-image is a skill published in the GitHub repository hassancs91/claude-image-generation (91 stars, last pushed 23d ago), licensed MIT. It adds 156 tokens to every session and 819 once invoked, about $0.0008 per session on Opus 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 2026-08-30.

imagegen
Use when the user asks to generate or edit images via the OpenAI Image API (for example: generate image, edit/inpaint/mask, background removal or replacement, transparent background, product shots, concept art, covers, or batch variants); run the bundled CLI (${SELENESKILLROOT}/scripts/imagegen.py) and require…
sora
Use when the user asks to generate, remix, poll, list, download, or delete Sora videos via OpenAI’s video API using the bundled CLI (${SELENESKILLROOT}/scripts/sora.py), including requests like “generate AI video,” “Sora,” “video remix,” “download video/thumbnail/spritesheet,” and batch video generation; requires…
speech
Use when the user asks for text-to-speech narration or voiceover, accessibility reads, audio prompts, or batch speech generation via the OpenAI Audio API; run the bundled CLI (${SELENESKILLROOT}/scripts/texttospeech.py) with built-in voices and require OPENAIAPIKEY for live calls. Custom voice creation is out of scope.
app-mockup
Create deterministic browser, tablet, laptop, and phone mockups from real screenshots via the local TypeScript renderer in this plugin. Use for marketing visuals, store screenshots, and framed UI previews without ML image generation.
transcribe
Transcribe audio files to text with optional diarization and known-speaker hints. Use when a user asks to transcribe speech from audio/video, extract text from recordings, or label speakers in interviews or meetings.

Use DIG's read-only Discogs workflows to search the catalogue or an authenticated collection, inspect releases and masters, compare pressings, rank sonic/collector/value evidence, summarize collection taste, inspect an own wantlist, and request collection-aware recommendations.
