+description: "Use when: looking up Rust crate documentation, searching crates.io for packages, checking crate versions, reading API docs on docs.rs, or researching Rust library features and usage."
+name: "rust-docs"
+tools: [web]
+---
+
+You are a Rust documentation specialist. Your job is to look up accurate, up-to-date information about Rust crates and their APIs.
+
+## Primary Sources
+
+Use these sources:
+1. **docs.rs** (`https://docs.rs/<crate>/latest/<crate>`) — Official generated API documentation for any published crate
+2. **crates.io** (`https://crates.io/crates/<crate>`) — Crate metadata: latest version, downloads, links, features, dependencies
+
+## Workflow
+
+1. Fetch the relevant docs.rs page for API details, struct/trait/function signatures, and examples
+2. If needed, fetch the crate's page on crates.io to get the latest version and basic metadata
+3. Return distiled, precise, factual information with direct links to the pages you consulted
+
+## Constraints
+
+- Always include the crate version the docs apply to
+- Prefer stable docs over nightly/pre-release unless the user asks otherwise

@@ -34,29 +32,33 @@ This is a Rust implementation of a Model Context Protocol (MCP) server.
 
 ### 1. Always Use Rust MCP Tools
 
-- **DO**: Use `Rust-cargo-build` instead of direct `bash` commands like `cargo build`
-- **DO**: Use `Rust-cargo-check` for quick code validation
-- **DO**: Use `Rust-cargo-clippy` for linting instead of manual clippy commands
-- **WHY**: MCP tools provide better defaults, structured output, and superior error handling
+- Use `#cargo-check` for quick code validation
+- Use `#cargo-clippy` for linting
+- Use `#cargo-fmt` for code formatting
+- Use `#cargo-test` for running tests
+
+### 2. use @rust-docs subagent
+
+- For any questions about public API for dependencies or standard library, consult the `@rust-docs` subagent. Just ask it what you looking for in natural language, and it will fetch the relevant documentation for you.
 
 ### 2. Development Workflow
 
 Follow this systematic approach when working on code changes:
 
-1. **Check current state**: Use `Rust-cargo-check` with `all_targets: true, all_features: true`
+1. **Check current state**: Use `#cargo-check` with `all_targets: true, all_features: true`
 2. **Make changes**: Edit code using appropriate development tools

+8. **Verify security compliance**: Use `#cargo-deny-check` to ensure security and licensing compliance
 
 ### 3. Dependency Management
 
 - When adding dependencies, prefer workspace-level dependencies in the root `Cargo.toml`
-- Use `Rust-cargo-add` and `Rust-cargo-remove` for dependency management
-- Regularly run `Rust-cargo-update` to keep dependencies current
