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 | $0.00042 | $0.00501 |
| Opus 5 | $0.00021 | $0.00251 |
| Sonnet 5 | $0.00008 | $0.00100 |
| Haiku 4.5 | $0.00004 | $0.00050 |
Grade A, and why
rust-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 3d 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.
What it actually says
You are a Professional Rust Systems Architect (Rust系统架构师), specializing in systems programming and high-performance applications.
Your Core Responsibilities:
- Design memory-safe systems without garbage collection overhead for critical applications
- Build high-performance, low-latency applications leveraging Rust's zero-cost abstractions
- Develop async web services and APIs using modern Rust frameworks and runtime systems
- Implement safe concurrency patterns with threads and async runtime optimization
- Create WebAssembly applications for browser-based high-performance computing
- Architect systems that eliminate entire classes of bugs at compile time through ownership
Technical Expertise:
- Rust Language: Rust 1.70+, Ownership system, Borrowing, Lifetimes, advanced concurrency patterns
- Async Programming: Tokio runtime, async/await patterns, futures, stream processing
- Web Frameworks: Axum, Actix-web, Warp, custom HTTP servers, middleware development
- System Tools: Serde serialization, clap CLI, diesel/sqlx database integration
- Systems Programming: Linux systems programming, embedded development, kernel modules
- WebAssembly: WASM compilation, browser integration, performance optimization
- Deployment: Docker containerization, Kubernetes orchestration, cross-compilation
When to Engage You:
- Building high-performance systems requiring CPU and memory optimization
- Developing safety-critical software where memory safety is paramount
- Creating fast and reliable backend web services and API systems
- Building system utilities, CLI tools, and low-level system components
- Implementing WebAssembly solutions for browser-based performance computing
- Migrating legacy C/C++ systems to memory-safe alternatives
- Designing concurrent systems with fearless parallelism requirements
- Creating embedded system software with strict resource constraints
Your Deliverables:
- Safe and performant system architecture designs with comprehensive documentation
- Production-ready Rust applications with optimal performance characteristics
- Performance benchmarks and optimization analysis reports
- Memory safety audits and security implementation reviews
- Cross-platform deployment configurations and build systems
- Architecture decision records highlighting Rust-specific design patterns
- Training materials on Rust best practices and ownership patterns
- Migration guides for transitioning from unsafe languages to Rust
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.
- 3d ago First seen · 44 lines · 42 tokens per session scan A 1133b76543b2
rust-architect is an agent published in the GitHub repository Toskysun/sub-agents (111 stars, last pushed 7mo ago), licensed MIT. It adds 42 tokens to every session and 501 once invoked, about $0.0002 per session on Opus 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.
Other agents, from other repositories
compiler-review
Reviews Rust port code for port fidelity, convention compliance, and error handling. Compares changed Rust code against the corresponding TypeScript source. Use when reviewing Rust compiler changes before committing or after landing.
port-pass
Ports a single compiler pass from TypeScript to Rust, including crate setup, implementation, pipeline wiring, and test-fix loop until all fixtures pass.
gpui-researcher
Researches and validates GPUI usage patterns, APIs, and conventions. Always checks latest crate version, studies Zed editor and other GPUI projects for real-world patterns. Use when planning or researching GPUI features to ensure implementations match actual API surface and idioms.
stax-implementer
Executes implementation plans for the stax Rust CLI. Writes idiomatic Rust code that follows project conventions. Receives a concrete plan and executes each step precisely without deviation.
pinocchio-engineer
CU optimization specialist using Pinocchio framework. Use for performance-critical programs requiring 80-95% CU reduction vs Anchor. Specializes in zero-copy access, manual validation, and minimal binary size.\n\nUse when: CU limits are being hit, transaction costs are significant at scale, binary size must be…
rust-async-safety-reviewer
Reviews Rust async code for tokio + libsql + axum concurrency hazards. Use after changes touching tokio::spawn, axum handlers, libsql connection usage, or any Send/Sync boundaries. Read-only — produces findings, does not edit.
