Svelte UI Design

What it does

When your agent uses it

• Modifying Svelte components
• Building UI pages
• Working with the component library
• Asking about frontend design patterns

Example prompts

• “Use the svelte-ui-design skill to guide designing and building Svelte 5 UI components in the bootc extension”
• “/svelte-ui-design”

Workflow steps

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

1. 1List all exports: Read node_modules/@podman-desktop/ui-svelte/dist/index.d.ts
2. 2Check component props: Read the .d.ts file for any component, e.g.
3. 3Browse all component dirs: ls node_modules/@podman-desktop/ui-svelte/dist/
4. 4Check package exports: Read node_modules/@podman-desktop/ui-svelte/package.json
5. 5See how we already use them: grep -r "from '@podman-desktop/ui-svelte'" packages/frontend/src/

What it can do on your machine

Read from SKILL.md and the folder at commit 4a3f7d8. 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

  Shell commands in SKILL.md call:

  • pnpm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • github.com
  • podman-desktop.io

  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

Svelte UI Design loads about 1.3k tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 311 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~98

When it runs · the whole SKILL.md, loaded when a task matches

~1.3k

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

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.
