pi-web: Skill for Claude Code

.pi/skills/piweb-design-deck/SKILL.md

piweb-design-deck is a skill for Claude Code, Codex from Epsilondelta-ai/pi-web. It costs 48 tokens per session (559 once invoked), scanned A, original, MIT.

A tool for showing UI mockups and design choices inside the pi-web conversation. It produces a structured preview deck instead of opening a separate design window.

In plain words
What is it for?
Use it to present interface mockups, compare visual directions, or review design options in pi-web.
Why use it?
It keeps design discussions in the same place as the conversation and avoids switching to an external browser window for previews.

This is Epsilondelta-ai/pi-web's own configuration. It tells Claude Code and Codex how to work on pi-web itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything pi-web configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

piweb-design-deck scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

pi-web Design Deck

Use this skill when the user wants visual design options shown inside pi-web.

When to use

  • User asks for design 시안, UI mockups, visual options, or design review options.
  • User is using pi-web and needs previews without an external browser.
  • design_deck fails to open or would require refresh/external window.

Output contract

Return a fenced JSON block with top-level type: "piweb_design_deck". Do not call the external design_deck tool for pi-web-native previews unless the user explicitly asks for the external deck.

{
  "type": "piweb_design_deck",
  "id": "stable-short-id",
  "title": "Deck title",
  "slides": [
    {
      "id": "slide-id",
      "title": "Decision title",
      "context": "Short context for the decision.",
      "options": [
        {
          "label": "Option A",
          "description": "What this direction optimizes for.",
          "recommended": true,
          "aside": "Tradeoffs, implementation notes, or why this is recommended.",
          "previewHtml": "<div style='...'>self-contained mockup</div>"
        }
      ]
    }
  ]
}

Rules

  • Use 2-4 options per slide.
  • Make options meaningfully different, not just color variants.
  • previewHtml must be self-contained inline HTML/CSS.
  • Keep HTML inert: no scripts, no network dependencies, no iframes inside preview HTML.
  • Prefer realistic product copy and layout over generic hero/card filler.
  • For pi-web itself, preserve the terminal/local-agent identity unless the user asks for a new brand.
  • If the user picks an option, treat it as the implementation contract.
  • label: concise direction name.
  • description: one-line summary.
  • recommended: only for the strongest option.
  • aside: why/impact/tradeoffs.
  • previewHtml: visual mockup.

pi-web-specific guidance

For pi-web design work, usually separate:

  • top shell command input: direct workspace command execution.
  • bottom composer: natural-language Pi instruction.
  • center panel: session transcript or first-run guidance.
  • mobile: compact brand instead of wide ASCII banners.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
