rust-crossRust cross-compilation skill. An agent skill from mohitmishra786/low-level-dev-skills.
Rust Cross is an agent skill from mohitmishra786/low-level-dev-skills. Rust cross-compilation skill. Use when building Rust binaries for a different target architecture or OS, using cross or cargo-zigbuild for hermetic cross-compilation, configuring .cargo/config.toml for cross targets, or targeting embedded and bare-metal systems. Activates on queries about Rust cross-compilation, rustup targets, cross tool, cargo-zigbuild, aarch64-unknown-linux-gnu, thumbv7m-none-eabi, or building for embedded.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/cross-targets.md`).
It sits in DevOps & Cloud. It works with Rust, Linux, Docker and WebAssembly. The repository describes itself as: A curated suite of AI agent skills for systems and low-level programming with C/C++, Rust, and Zig toolchains, covering compilers, debuggers, profilers, build systems…. The licence is MIT.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit bdc5847. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
cargoFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
ziglang.orgFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Rust Cross loads about 1.4k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 110 tokens; SKILL.md has 260 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Rust cross-compilation skill. An agent skill from mohitmishra786/low-level-dev-skills. Rust Cross is an agent skill from mohitmishra786/low-level-dev-skills. Rust cross-compilation skill.
Rust Cross fits situations like: building Rust binaries for a different target architecture; cargo-zigbuild for hermetic cross-compilation; configuring .cargo/config.toml for cross targets; targeting embedded and bare-metal systems.
Run `npx skills add mohitmishra786/low-level-dev-skills --skill rust-cross -a claude-code`. Or copy the skill folder (skills/rust/rust-cross in mohitmishra786/low-level-dev-skills) into .claude/skills/rust-cross in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mohitmishra786/low-level-dev-skills --skill rust-cross -a codex`. Or copy the skill folder (skills/rust/rust-cross in mohitmishra786/low-level-dev-skills) into .agents/skills/rust-cross in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mohitmishra786/low-level-dev-skills --skill rust-cross -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rust-cross, .gemini/skills/rust-cross, .github/skills/rust-cross and .opencode/skills/rust-cross in your project.
Going by SKILL.md and its folder, Rust Cross needs the command-line tools its instructions call (cargo). Our summary lists: Docker.
SKILL.md names 1 domain. In commands or code: ziglang.org; the agent is likely to contact it when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Rust Cross is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 1.1k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Rust Cross: Fungi (enbop/fungi, 132 stars), Vuio (vuiodev/vuio, 172 stars), Frb Docker (fzyzcjy/flutter_rust_bridge, 5.4k stars) and Docker Buildx Stale Rust Binary (divinevideo/divine-mobile, 266 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
