What it does

Create Skeleton App is an agent skill from AtomUI/AtomUI. Use when creating or updating a minimal AtomUI/Avalonia skeleton application, sample app, or reproduction project that demonstrates AtomUI setup, controls, themes, and basic runtime wiring.

Its SKILL.md is about 260 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 Development. It works with Avalonia. The repository describes itself as: An enhancement and extension library for Avalonia, bringing the Ant Design design language, modern controls, theming, native integrations, and cross-platform UI capabilities to… The licence is LGPL-3.0.

When your agent uses it

Updating a minimal AtomUI/Avalonia skeleton application
Reproduction project that demonstrates AtomUI setup
Basic runtime wiring

Example prompts

“/create-skeleton-app”

Workflow steps

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

Confirm the target location, framework, and purpose from the request or nearby project structure.
Reuse existing repository conventions for project files, package versions, namespaces, theme setup, and control imports.
Keep the skeleton small but runnable
Avoid introducing unrelated architecture, services, or styling.
Run the smallest useful build command for the created project and report the result.

What it can do on your machine

Read from SKILL.md and the folder at commit e82b36c. 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

Create Skeleton App loads about 260 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 111 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~52
When it runs · the whole SKILL.md, loaded when a task matches: ~260

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.

Create Skeleton App

Use this skill when the user asks for a minimal runnable AtomUI or Avalonia sample application.

Workflow

Confirm the target location, framework, and purpose from the request or nearby project structure.
Reuse existing repository conventions for project files, package versions, namespaces, theme setup, and control imports.
Keep the skeleton small but runnable:
- Application entry point
- Main window or view
- Theme/resource registration
- One or two representative AtomUI controls
Avoid introducing unrelated architecture, services, or styling.
Run the smallest useful build command for the created project and report the result.

Notes

Prefer existing templates and examples already present in the repository over inventing new structure.
