Install
Works with every agent the skills CLI supports.
npx skills add https://github.com/laurigates/claude-plugins --skill rust-development- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads rust-development automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.
SKILL.md
The instructions your agent reads when the skill is triggered.
Rust Development
Expert knowledge for modern systems programming with Rust, focusing on memory safety, fearless concurrency, and zero-cost abstractions.
When to Use This Skill
| Use this skill when... | Use sibling skill instead when... |
|---|---|
| Writing Rust code, ownership, lifetimes, async/await | Configuring lint rules in detail -- use clippy-advanced |
| Choosing crates from the ecosystem (Tokio, Serde) | Detecting unused dependencies -- use cargo-machete |
| Designing module structure or trait hierarchies | Running tests with parallel isolation -- use cargo-nextest |
| Learning idiomatic Rust patterns and edition features | Generating coverage reports -- use cargo-llvm-cov |
Core Expertise
Modern Rust Ecosystem
- Cargo: Build system, package manager, and workspace management
- Rustc: Compiler optimization, target management, and cross-compilation
- Clippy: Linting for idiomatic code and performance improvements
- Rustfmt: Consistent code formatting following Rust style guidelines
- Rust-analyzer: Advanced IDE support with LSP integration
Language Features
- Rust 2024 edition: RPITIT, async fn in traits, impl Trait improvements
- Const generics and compile-time computation
- Generic associated types (GATs)
- Let-else patterns and if-let chains
Key Capabilities
Ownership & Memory Safety
- Implement ownership patterns with borrowing and lifetimes
- Design zero-copy abstractions and efficient memory layouts
- Apply RAII patterns through Drop trait and smart pointers (Box, Rc, Arc)
- Leverage interior mutability patterns (Cell, RefCell, Mutex, RwLock)
- Use Pin/Unpin for self-referential structures
Async Programming & Concurrency
- Tokio: Async runtime for high-performance network applications
- async-std: Alternative async runtime with familiar API design
- Futures: Composable async abstractions and stream processing
- Rayon: Data parallelism with work-stealing thread pools
- Design lock-free data structures with atomics and memory ordering
Error Handling & Type Safety
- Design comprehensive error types with thiserror and anyhow
- Implement Result<T, E> and Option<T> patterns effectively
- Use pattern matching for exhaustive error handling
- Apply type-state patterns for compile-time guarantees
Performance Optimization
- Profile with cargo-flamegraph, perf, and criterion benchmarks
- Optimize with SIMD intrinsics and auto-vectorization
- Implement zero-cost abstractions and inline optimizations
- Use unsafe code judiciously with proper safety documentation
Testing & Quality Assurance
- Unit Testing: #[test] modules with assertions
- Integration Testing: tests/ directory for end-to-end validation
- Criterion: Micro-benchmarking with statistical analysis
- Miri: Undefined behavior detection in unsafe code
- Fuzzing: cargo-fuzz for security and robustness testing

Best Practices
Idiomatic Rust Patterns
// Use iterators over manual loops
let sum: i32 = numbers.iter().filter(|x| **x > 0).sum();
// Prefer combinators for Option/Result
let value = config.get("key")
.and_then(|v| v.parse().ok())
.unwrap_or_default();
// Use pattern matching effectively
match result {
Ok(value) if value > 0 => process(value),
Ok(_) => handle_zero(),
Err(e) => return Err(e.into()),
}
// Let-else for early returns
let Some(config) = load_config() else {
return Err(ConfigError::NotFound);
};

How do I install rust-development?
Run npx skills add https://github.com/laurigates/claude-plugins --skill rust-development in your project. The skills CLI detects the agents you use and copies the skill into the right folder. For Claude Code you can also place the skill folder at ~/.claude/skills/rust-development/ (personal) or .claude/skills/rust-development/ (project).
Which AI agents can use rust-development?
Any agent that supports the open Agent Skills format (a folder with a SKILL.md file), including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, Windsurf, Cline, OpenCode and more.
Is rust-development safe to install?
No partner security audit is available yet. Skills can run commands and scripts, so read the SKILL.md and any bundled files before installing.
Who maintains rust-development?
It is published by laurigates in laurigates/claude-plugins. It has 104 recorded installs.

USE FOR: create app registration, register Azure AD app, configure OAuth, set up authentication, add API permissions, generate service principal, MSAL example, console app auth, Entra ID setup, Azure AD authentication. DO NOT USE FOR: Key Vault secrets (use azure-keyvault-expiration-audit), general Azure resource security guidance.
google-agents-cli-adk-code
google/agents-cli
This skill should be used when the user wants to "write agent code", "build an agent with ADK", "add a tool", "create a callback", "define an agent", "use state management" — in a project that needs ADK (Agent Development Kit) API patterns and code examples. It provides a quick reference for agent types, tool definitions, orchestration patterns, callbacks, state management, the graph Workflow API, and reference recipes to study. Do NOT use for scaffolding (use google-agents-cli-scaffold) or deployment (use google-agents-cli-deploy).
embedded-captions
heygen-com/hyperframes
Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
