$ npx skills add kurealnum/dotfiles --skill rust-testing -a claude-code

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

GitHub CLI
$ gh skill install kurealnum/dotfiles rust-testing --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/kurealnum/dotfiles.git skills-src && mkdir -p .claude/skills && cp -r skills-src/.agents/skills/rust-testing .claude/skills/rust-testing && rm -rf skills-src

What it does

Rust Testing is an agent skill from kurealnum/dotfiles. Rust testing patterns including unit tests, integration tests, async testing, property-based testing, mocking, and coverage. Follows TDD methodology.

Its SKILL.md is about 2.9k 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 Testing & QA, covering Unit testing, Test-driven development and Test strategy. It works with Rust.

When your agent uses it

  • Tasks that involve Unit testing
  • Tasks that involve Test-driven development
  • Tasks that involve Test strategy

Example prompts

  • “/rust-testing”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Identify target code — Find the function, trait, or module to test
  2. Write a test — Use #[test] in a #[cfg(test)] module, rstest for parameterized tests, or proptest for property-based tests
  3. Mock dependencies — Use mockall to isolate the unit under test
  4. Run tests (RED) — Verify the test fails with the expected error
  5. Implement (GREEN) — Write minimal code to pass
  6. Refactor — Improve while keeping tests green
  7. Check coverage — Use cargo-llvm-cov, target 80%+

What it can do on your machine

Read from SKILL.md and the folder at commit bcd8741. 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

Rust Testing loads about 2.9k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 331 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
~2.9k

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 331 words (~2,904 tokens).

“Comprehensive Rust testing patterns for writing reliable, maintainable tests following TDD methodology.”

Rust testing patterns including unit tests, integration tests, async testing, property-based testing, mocking, and coverage.

When should I use Rust Testing?

Rust Testing fits situations like: tasks that involve Unit testing; tasks that involve Test-driven development; tasks that involve Test strategy.

How do I install Rust Testing in Claude Code?

Run `npx skills add kurealnum/dotfiles --skill rust-testing -a claude-code`. Or copy the skill folder (.agents/skills/rust-testing in kurealnum/dotfiles) into .claude/skills/rust-testing in your project. Claude Code loads it when a task matches its description.

How do I install Rust Testing in Codex?

Run `npx skills add kurealnum/dotfiles --skill rust-testing -a codex`. Or copy the skill folder (.agents/skills/rust-testing in kurealnum/dotfiles) into .agents/skills/rust-testing in your project. Codex loads it when a task matches its description.

Can I use Rust Testing in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add kurealnum/dotfiles --skill rust-testing -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-testing, .gemini/skills/rust-testing, .github/skills/rust-testing and .opencode/skills/rust-testing in your project.

What does Rust Testing need to run?

Going by SKILL.md and its folder, Rust Testing needs the command-line tools its instructions call (cargo).

Does Rust Testing access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Rust Testing safe to install?

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.

What licence does Rust Testing use?

No licence was found for Rust Testing or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Rust Testing use?

About 2.9k tokens (SKILL.md is roughly 12k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Rust Testing?
