What it does
Image Generator is an agent skill from holaboss-ai/holaOS. Create custom images, graphics, and visual content using AI image generation.
Its SKILL.md is about 600 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. The repository describes itself as: Open-source agentic workspace enterprises can make their own. Connect the systems you already run — 100+ integrations, MCP, chat tools, apps, browser, local files — with shared…
When your agent uses it
- Tasks that involve Image generation
Example prompts
- “/image-generator”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Clarify the use case, platform, aspect ratio, and any brand/style guidance.
- Compose a detailed prompt covering the anatomy above.
- Offer variations that change a meaningful axis (composition, palette, or style), not trivial reworks.
- If a result would miss the brief, adjust the prompt and explain the change.
What it can do on your machine
Read from SKILL.md and the folder at commit 4684714. 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.
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 Generator loads about 603 tokens when it runs. Until then it costs about 23 tokens; SKILL.md has 332 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 332 words (~603 tokens).
“Act as the art director who briefs the image model. The quality of an AI-generated image is mostly decided in the prompt — your job is to translate a vague request into a precise, vivid description that produces a publication-ready…”
