metis: Skill for Claude Code

.claude/skills/20-interactive-widgets/SKILL.md

interactive-widgets is a skill for Claude Code from terrene-foundation/metis. It costs 73 tokens per session (921 once invoked), scanned A, original, Apache-2.0.

A collection of patterns for building AI interfaces with interactive widgets instead of text alone. These widgets can include generated components, forms, streamed structured responses and actions that return results.

In plain words
What is it for?
Use it when designing a widget protocol, generating forms from AI responses, streaming structured components, rendering widgets in the browser, handling widget events, or managing their state and errors.
Why use it?
It gives developers a way to design how an AI backend describes interface elements and how a front end displays and handles them. This avoids inventing a separate approach for every dynamic AI screen.

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

interactive-widgets 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 1mo 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.

Interactive Widget System

Production-ready patterns for building interactive widget systems that integrate with AI/LLM backends for dynamic, structured user interfaces.

Interactive widget patterns for:

  • LLM-driven widget generation
  • Streaming response with structured components
  • Dynamic form builders
  • Action-response patterns
  • Widget protocol design

Quick Patterns

Widget Protocol (JSON)

{
  "type": "form",
  "id": "user-input-form",
  "content": {
    "fields": [
      {
        "type": "text",
        "name": "query",
        "label": "Enter your question",
        "required": true
      }
    ],
    "actions": [
      {
        "type": "submit",
        "label": "Send",
        "action": "submit_query"
      }
    ]
  }
}

Backend Widget Generation (Python)

def generate_widget_response(user_query: str) -> dict:
    """Generate structured widget response from LLM."""
    response = llm.generate(
        prompt=f"Generate a widget response for: {user_query}",
        output_schema=WidgetSchema
    )
    return {
        "type": response.widget_type,
        "content": response.content,
        "actions": response.available_actions
    }

Frontend Widget Renderer (Dart)

Widget buildWidget(Map<String, dynamic> widgetData) {
  switch (widgetData['type']) {
    case 'form':
      return FormWidget(data: widgetData['content']);
    case 'card':
      return CardWidget(data: widgetData['content']);
    case 'table':
      return TableWidget(data: widgetData['content']);
    default:
      return TextWidget(data: widgetData['content']);
  }
}

Changes

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.
