$ npx skills add bobmatnyc/claude-mpm --skill toolchains-rust-core -a claude-code

Project install by default; add -g for ~/.claude/skills/.

GitHub CLI
$ gh skill install bobmatnyc/claude-mpm toolchains-rust-core --agent claude-code

Project scope by default; add --scope user for a personal install. Needs GitHub CLI 2.90.0 or later (public preview).

Manual copy
$ git clone --depth 1 https://github.com/bobmatnyc/claude-mpm.git skills-src && mkdir -p .claude/skills && cp -r skills-src/src/claude_mpm/skills/bundled/toolchains/rust/core .claude/skills/toolchains-rust-core && rm -rf skills-src

Rust 2024 edition core patterns: idiomatic code, error handling, traits/generics, macros, async/concurrency, testing, and project architecture

  • Tasks that involve Error handling
  • SKILL.md covers Quick Start, Idiomatic Patterns, Error Handling and Traits and Generics, plus 3 more sections
  • Calls cargo

What it does

Toolchains Rust Core is an agent skill from bobmatnyc/claude-mpm. Rust 2024 edition core patterns: idiomatic code, error handling, traits/generics, macros, async/concurrency, testing, and project architecture

Its SKILL.md is about 8.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Error handling. It works with Rust. The repository describes itself as: Claude Multi-Agent Project Manager — multi-channel orchestration, GitHub-first SDK mode, and plugin system for Claude.

When your agent uses it

  • Tasks that involve Error handling

Example prompts

  • “/toolchains-rust-core”

What it can do on your machine

Read from SKILL.md and the folder at commit 25203d3. It shows what the files ask for, not the result of running them.

  • Tool permissions

    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.

  • Runs code

    Shell commands in SKILL.md call:

    • cargo

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Toolchains Rust Core loads about 8.7k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 1,678 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~8.7k

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.

Safety

Auto-check passed

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,678 words (~8,729 tokens).
