What it does

Add Astro Icon is an agent skill from t4t5/rencal. Turn raw SVG markup into an Astro icon component in website/src/icons/. Use when the user provides SVG markup and wants it added as a website Astro icon.

Its SKILL.md is about 750 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 Frontend & Design, covering Static sites and blogs. It works with Astro and Bash. The repository describes itself as: A modern desktop calendar. Built for Omarchy. The licence is MIT.

When your agent uses it

  • The user provides SVG markup and wants it added as a website Astro icon
  • Tasks that involve Static sites and blogs

Example prompts

  • “/add-astro-icon”

Workflow steps

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

  1. Get the SVG: The user will give you raw SVG markup (often copy-pasted from Streamline, Figma, etc.).
  2. Pick a filename: Use a short kebab-case name describing the icon (e.g. settings.astro, arrow-right.astro). Infer obvious icon names…
  3. Transform the SVG
  4. Write the file to website/src/icons/.astro immediately. Use bash with a quoted heredoc instead of the write tool to avoid slow…

What it can do on your machine

Read from SKILL.md and the folder at commit 4388156. 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, svg and astro).

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • w3.org

    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

Add Astro Icon loads about 752 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 286 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~752

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.

description
Turn raw SVG markup into an Astro icon component in website/src/icons/. Use when the user provides SVG markup and wants it added as a website Astro icon.

You are turning raw SVG markup the user provides into an Astro icon component in website/src/icons/.

Workflow

  1. Get the SVG: The user will give you raw SVG markup (often copy-pasted from Streamline, Figma, etc.).

  2. Pick a filename: Use a short kebab-case name describing the icon (e.g. settings.astro, arrow-right.astro). Infer obvious icon names without asking. For common brand logos, use the brand name (e.g. GitHub → github.astro). Ask the user only if the name is truly ambiguous.

  3. Transform the SVG:

    • Add this Astro frontmatter at the top:

      astro
      ---
interface Props {
  class?: string
}

const { class: className } = Astro.props
---

    • On the <svg> tag: keep xmlns, fill, and viewBox. Add class={className}. Remove hardcoded width and height — size is controlled by Tailwind (size-4, size-6, etc.).

    • Replace every hardcoded stroke color (e.g. stroke="#000000") with stroke="currentColor". Same for fill if it's a color — but leave fill="none" alone. Brand icons that should inherit text color should use fill="currentColor".

    • Strip noise: id attributes, <desc> tags, <title> tags, and any other vendor metadata.

    • Keep stroke-width, stroke-linecap, stroke-linejoin, d, and other geometry-defining attributes. Preserve valid Astro/HTML attribute casing for SVG markup.

  4. Write the file to website/src/icons/<name>.astro immediately. Use bash with a quoted heredoc instead of the write tool to avoid slow line-by-line UI rendering:

    bash
    cat > website/src/icons/<name>.astro <<'EOF'
...
EOF

Speed rules

  • Do not inspect existing icon files unless necessary.
  • Infer obvious icon names without asking.
  • For common brand logos, use the brand name.
  • Immediately write website/src/icons/<name>.astro after transforming.
  • Prefer bash with a quoted heredoc for file creation; do not use the write tool unless bash is unavailable.
  • Do not run checks unless the user asks.

Example

Input:

svg
<svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" id="Foo" height="24" width="24">
  <desc>Some vendor blurb</desc>
  <g id="group"><path id="p1" stroke="#000000" d="M6 0v14" stroke-width="2" /></g>
</svg>

Output (website/src/icons/foo.astro):

astro
---
interface Props {
  class?: string
}

const { class: className } = Astro.props
---

<svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" class={className}>
  <g>
    <path stroke="currentColor" d="M6 0v14" stroke-width="2" />
  </g>
</svg>

Usage: <FooIcon class="size-4 text-primary" /> when imported with an alias, or import the .astro component directly and render it with class="size-4 text-primary".
