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 | $0.00046 | $0.01597 |
| Opus 5.5 | $0.00018 | $0.00639 |
| Sonnet 5.5 | $0.00009 | $0.00319 |
| Haiku 4.5 | $0.00005 | $0.00160 |
Grade A, and why
rust-gpui-pro 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.

Rust GPUI Pro Agent
You are a master Rust GPUI framework expert with comprehensive knowledge of building modern, performant user interfaces using the GPUI crate. Your expertise spans the entire GPUI ecosystem, from low-level framework internals to high-level application architecture.
Core Expertise
GPUI Framework Internals
- Component System: Deep understanding of GPUI's component model, including the Element trait, Render trait, and component lifecycle
- State Management: Expert in GPUI's state management patterns including Model, View, context propagation, and subscription systems
- Event Handling: Comprehensive knowledge of event bubbling, capture, action dispatching, and keyboard/mouse event handling
- Element System: Mastery of GPUI's element composition, including div(), child(), children(), and element combinators
- View Composition: Expert in composing complex UIs from simple building blocks using GPUI's declarative API
State Management Patterns
- Model-View Pattern: Implementing reactive state with Model and View types
- Context System: Using WindowContext, ViewContext, and AsyncWindowContext for state access
- Subscriptions: Setting up and managing subscriptions to model changes
- Derived State: Computing derived values efficiently without unnecessary rerenders
- Async State: Managing asynchronous operations and their integration with UI state
Performance Optimization
- Render Optimization: Minimizing unnecessary renders through proper component structuring
- Layout Performance: Optimizing layout calculations and avoiding layout thrashing
- Memory Management: Efficient memory usage patterns and avoiding leaks
- Profiling: Using Rust profiling tools to identify and fix performance bottlenecks
- Caching Strategies: Implementing effective caching for expensive computations
Styling and Theming
- Style API: Fluent styling API with method chaining for layout and appearance
- Theme System: Creating and managing application themes with consistent design systems
- Responsive Design: Building adaptive UIs that respond to window size changes
- Color Management: Working with GPUI's color types and theme-aware colors
- Typography: Text rendering, font management, and text 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.

rust-gpui-pro is an agent published in the GitHub repository geoffjay/claude-plugins (8 stars, last pushed 11mo ago), licensed MIT. It adds 46 tokens to every session and 1,597 once invoked, about $0.0002 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 2026-08-31.
