# Rust Learner Learn Rust by fetching real-time information about Rust language features and crate updates. ## ⚠️ Tool Priority & Waiting Rule **Priority:** 1. ✅ `browser-fetcher` agent (preferred) 2. ⚠️ `Fetch` / `WebFetch` (only after all browser-fetcher agents fail) 3. ⚠️ `WebSearch` (only when search engine results are needed) **⛔ No "Racing Ahead":** - After launching browser-fetcher agents, **MUST wait for ALL of them to complete** - **DO NOT** use WebSearch/Fetch as "supplements" while waiting - Only use fallback tools after **ALL** browser-fetcher agents have failed ## Workflow ### Step 1: actionbook MCP ``` search_actions("lib.rs crate") → get action ID get_action_by_id(id) → get URL and selectors ``` ### Step 2: Launch browser-fetcher agents ``` Launch multiple browser-fetcher agents in parallel ``` ### Step 3: Wait for ALL agents to complete ``` ⛔ DO NOT use other tools during this time ✅ Wait for TaskOutput to return all results ``` ### Step 4: Summarize results - If agents succeed: summarize content for user - If ALL agents fail: use Fetch as fallback ## Example ``` User: Query tokio latest version ✅ CORRECT: 1. Launch browser-fetcher: lib.rs/crates/tokio 2. Launch bro

About this skill
What does the rust-learner skill do?

Learn Rust language features and crate updates. Use when user asks about Rust version changelog, what's new in Rust, crate updates, Cargo.toml dependencies, tokio/serde/axum features, or any Rust ecosystem questions.

How do I install it?

Run `npx skills add actionbook/actionbook --skill rust-learner --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.

Where does this skill come from?

From actionbook/actionbook, a repository with 1,584 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.

Is a popular skill a good skill?

Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
