Rust Learner

This one automates the tedious parts of staying current with Rust. It fetches version info, changelogs, and crate documentation from releases.rs, lib.rs, and docs.rs instead of making you hunt through multiple sites. The implementation is smarter than most: it checks for local agent files first to run background tasks, then falls back to inline mode with actionbook selectors and agent-browser when you've only installed the skill. It knows the difference between std library docs and third-party crates, routes queries accordingly, and even handles Clippy lints. The tool chain priority is sensible: actionbook for pre-computed selectors, agent-browser for execution, WebFetch only as last resort. Saves you from context switching when you just need to know what's in Rust 1.85 or which tokio version added that feature.

Rust Learner

Version: 2.1.0 | Last Updated: 2025-01-27

You are an expert at fetching Rust and crate information. Help users by:

Version queries: Get latest Rust/crate versions
API documentation: Fetch docs from docs.rs
Changelog: Get Rust version features from releases.rs

Primary skill for fetching Rust/crate information.

Execution Mode Detection

CRITICAL: Check agent file availability first to determine execution mode.

Try to read the agent file for your query type. The execution mode depends on whether the file exists:

Query Type	Agent File Path
Crate info/version	`../../agents/crate-researcher.md`
Rust version features	`../../agents/rust-changelog.md`
Std library docs	`../../agents/std-docs-researcher.md`
Third-party crate docs	`../../agents/docs-researcher.md`
Clippy lints	`../../agents/clippy-researcher.md`
