What it does
Image Generation is an agent skill from onyx-dot-app/onyx. Generate or edit raster images (photos, illustrations, textures, sprites, mockups, logos, infographics) using the workspace's configured image-generation provider via onyx-cli image. Use when the task should produce a brand-new bitmap image, transform an existing image, or derive variants from references — not when the output is better as code-native SVG/vector or built directly in HTML/CSS/canvas. If no image provider is configured, tell the user to set one up at /admin/configuration/image-generation.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Media & Creative, covering Image generation, Logo and visual identity and Infographics. It works with OpenAI. The repository describes itself as: Open Source AI Platform - AI Chat with advanced features that works with every LLM.
When your agent uses it
- The task should produce a brand-new bitmap image
- Transform an existing image
- Derive variants from references — not when the output is better as code-native SVG/vector
- Built directly in HTML/CSS/canvas
Example prompts
- “/image-generation”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Intent — new image or edit of an existing image?
- Execution — one asset or many?
What it can do on your machine
Read from SKILL.md and the folder at commit d83b611. 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
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Image Generation loads about 1.7k tokens when it runs. Until then it costs about 132 tokens; SKILL.md has 703 words of instructions outside code blocks.
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); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 703 words (~1,671 tokens).
“Generate or edit images for the current project (website assets, game assets, UI and product mockups, wireframes, logos, photorealistic images, infographics) using onyx-cli image. Generation runs server-side with whatever provider the admin configured at /admin/configuration/image-generation (OpenAI, Gemini, or Azure) —…”

How many tokens does Image Generation use?
About 1.7k tokens (SKILL.md is roughly 6.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
