What it does
Img Gen Avatar is an agent skill from 4thfever/cultivation-world-simulator. Use when working on tools/imggen avatar image generation, OpenAI-compatible image API config, human or yaoguai portrait prompts, qi-refining base generation, image-to-image realm edits, white-background postprocessing, manifests, or prompt rules that preserve pixel-art identity while changing cultivation realms.
Its SKILL.md is about 640 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 Game Development, covering Sprites and pixel art and Image generation. It works with OpenAI. The repository describes itself as: 基于 AI Agent 工作流的修仙世界模拟器，旨在还原智能、开放的仙侠世界。| An open-source Cultivation World Simulator using Agentic Workflow to create a dynamic, emerging Xianxia world.
When your agent uses it
- Working on tools/imggen avatar image generation
- OpenAI-compatible image API config
- Yaoguai portrait prompts
- Qi-refining base generation
Example prompts
- “/img-gen-avatar”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Generate only qi-refining base portraits with text-to-image.
- Generate foundation, golden core, and nascent soul portraits with image edits based directly on the qi-refining image.
What it can do on your machine
Read from SKILL.md and the folder at commit 471fe74. 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
Img Gen Avatar loads about 641 tokens when it runs. Until then it costs about 82 tokens; SKILL.md has 279 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 279 words (~641 tokens).
