Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00074 | $0.01668 |
| Opus 5.5 | $0.00030 | $0.00667 |
| Sonnet 5.5 | $0.00015 | $0.00334 |
| Haiku 4.5 | $0.00007 | $0.00167 |
Grade A, and why
ephemeral-generative-ui-architect 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 7d 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.

Ephemeral Generative UI Architect (2026 Edition)
English
Orchestration & Integration
Connects and orchestrates with vercel-ai-sdk-expert, senior-frontend, ui-ux-pro-max, design-system-architect, gemini-agent-booster, and multi-agent-orchestration.
Description
Standard UIs are static and pre-compiled. In the Gemini 4 Pro era, interfaces are ephemeral: generated in real-time based on the user's immediate intent, and destroyed when no longer needed. This skill orchestrates Generative UI systems using React Server Components (RSC), Tool-Driven UI injection, and Vercel AI SDK, allowing LLMs to directly stream fully functional, interactive components (charts, forms, dashboards) instead of markdown text.
Trigger Conditions
- The user requests an interface that adapts entirely to the data context (e.g., "Show me a dashboard of my spending" -> AI generates a custom chart component on the fly).
- Designing AI-native chat interfaces that render interactive widgets (booking forms, map components) instead of plain text responses.
- Integrating Vercel AI SDK
streamUIor tool-call-to-component mappings.
Core Architecture (2026 Standard)
- Tool-to-UI Mapping: The AI decides to call a tool (e.g.,
getWeather). The server intercepts this tool call and streams a<WeatherWidget />React Server Component directly to the client. - Zero-Client-State (Ephemeral): The UI state exists only within the LLM conversation history. If the chat resets, the UI resets.
- Optimistic Rendering: The client immediately renders a loading skeleton (e.g.,
<WeatherSkeleton />) the millisecond the LLM begins emitting the tool call token, replaced by the final RSC once execution completes.
Sovereign Visual Hierarchy in Ephemeral UI
Even when rendered dynamically on-the-fly, AI-generated components MUST strictly observe Sovereign Visual Hierarchy:
- Container Grounding: Wrap streamed widgets in Level 1 Surface containers (
bg-white dark:bg-neutral-900 border border-neutral-200/80 dark:border-neutral-800 rounded-xl shadow-xs). - Typographic Rhythm: Eyebrow badge (
text-[11px] font-semibold uppercase tracking-wider text-neutral-500) -> Title (text-lg font-semibold tracking-tight text-neutral-900 dark:text-neutral-50) -> Body (text-sm text-neutral-600 dark:text-neutral-300). - Tabular Numerals: Enforce
tabular-numson all streaming counters, prices, metrics, and telemetry stats. - Single Primary CTA: Exactly one primary action per streamed card (e.g., "Confirm Booking"); secondary options use subtle ghost styling.
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.

ephemeral-generative-ui-architect is a skill published in the GitHub repository roedyrustam/vibes-plug (75 stars, last pushed yesterday), licensed MIT. It adds 74 tokens to every session and 1,668 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-29.
