Rust

What this skill does

Writes, debugs, and optimizes Rust code, crates, and Cargo builds: ownership, lifetimes, traits, async, unsafe, and FFI. Use when the borrow checker rejects code, when rustc reports value moved, cannot borrow as mutable, does not live long enough, missing lifetime specifier, trait bound not satisfied, or not dyn compatible; when a future cannot be sent between threads, a Mutex guard crosses an await, a task blocks the async runtime, or select! loses data; when code deadlocks, panics on unwrap, or hits BorrowMutError; when cargo builds are slow, features unify unexpectedly, two versions of one crate collide, or the build fails only in CI; when writing unsafe, C FFI, proc macros, serde derives, no_std firmware, or wasm; when cross-compiling to musl or another target; when profiling, benchmarking, or shrinking a Rust binary. Not for C++ or language-agnostic concurrency theory.

Rust is part of the Developer Tools category — developer tools that help your agent write, review, debug, and ship code. You can install it on its own or alongside other developer tools skills from the OpenClaw catalog.

How to install Rust

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for rust and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Rust with a single command:

openclaw skills add rust

This pulls rust from ClawHub and installs it into ~/.openclaw/skills/rust/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Rust

Once installed, Rust activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.

Turning social content into video

Rust works with social content. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — renders a script or a set of clips into a finished vertical video with captions, ready to post.

It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download .zip button above to grab rust-1.0.3.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/rust/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
