CopilotKit/OpenGenerativeUI is an open-source showcase for AI-generated user interfaces, where an agent creates live interactive HTML and SVG visualizations instead of returning only text. It is used to build algorithm demonstrations, 3D scenes, charts, diagrams, forms, simulations, and mathematical plots rendered in sandboxed iframes. The catalogue skills and instruction support working with this generative UI project.

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 | $0.02348 | $0.02348 |
| Opus 5.5 | $0.00939 | $0.00939 |
| Sonnet 5.5 | $0.00470 | $0.00470 |
| Haiku 4.5 | $0.00235 | $0.00235 |
Grade A, and why
OpenGenerativeUI CLAUDE.md 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 2mo 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.

CopilotKit + LangGraph Todo Demo
Purpose
This repository serves as both a showcase and template for building AI agents with CopilotKit and LangGraph. It demonstrates how CopilotKit can drive interactive UI beyond just chat, using a collaborative todo list as the primary example.
Target audience: Developers evaluating CopilotKit or starting new projects with AI agents.
Core Concept
The todo list demonstrates agent-driven UI where:
- The agent can manipulate application state (adding todos, updating status, organizing tasks)
- Users can interact with the same state (editing titles, checking off tasks, deleting todos)
- Both agent and user changes update the same shared state
- The UI reactively updates based on agent state changes
This uses CopilotKit's v2 agent state pattern where state lives in the agent and syncs to the frontend.

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.

OpenGenerativeUI CLAUDE.md is an instructions file published in the GitHub repository CopilotKit/OpenGenerativeUI (3,403 stars, last pushed 24d ago), licensed MIT. It adds 2,348 tokens to every session, about $0.0094 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 2026-08-30.
