Rust Core

Q: What is a Claude Code skill and how does the Rust Core skill fit in?

A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Rust Core is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.

Shared reference for the Rust cluster: the library-vs-application error strategy (thiserror vs anyhow) that everything turns on, type-driven design conventions, the cargo tooling matrix, and the shared guardrails both spokes obey. USE WHEN choosing a Rust error type, shaping a public API, or wiring the cargo/CI toolchain — the decisions both patterns and testing depend on.

From the source SKILL.md

Shared model for the rust cluster. Both spokes — rust-patterns (write) and rust-testing (verify) — depend on these conventions; keep them consistent here so the two never contradict each other (e.g. an error type designed in code and asserted in a test).

What this skill does

Rust Core is a community-contributed Claude Code skill in the languages sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/rust-core/ and loads when your prompt matches the skill's trigger.

When to invoke it: USE WHEN choosing a Rust error type, shaping a public API, or wiring the cargo/CI toolchain — the decisions both patterns and testing depend on.

Who uses this skill
