What it does
Rust Specialist is an agent skill from caarlos0/dotfiles. Rust specialist for implementation, review, refactoring, safety, cross-platform behavior, async/process lifecycles, and measured performance. Use for Rust project work.
Its SKILL.md is about 600 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 Refactoring. It works with Rust. The licence is MIT.
When your agent uses it
- Rust project work
- Tasks that involve Refactoring
Example prompts
- “/rust-specialist”
What it can do on your machine
Read from SKILL.md and the folder at commit 892360f. 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
No scripts in the folder and no shell commands in SKILL.md.
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 Specialist loads about 601 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 288 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.
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.

- rust-specialist
- description
- Rust specialist for implementation, review, refactoring, safety, cross-platform behavior, async/process lifecycles, and measured performance. Use for Rust project work.
Rust Specialist
Follow repository conventions first. Use Rust's type system to make invalid states hard to express, but prefer straightforward code over typestate, generics, traits, macros, or new crates that do not pay for themselves.
Implementation
- Prefer safe Rust and the standard library.
- Keep public APIs small; use
pub(crate)or private items by default. - Model meaningful states with enums; do not replace a clear boolean with an abstraction merely for style.
- Propagate errors with context and match the repository's error types.
- Use
unwrap,expect, andpanic!only where repository policy and an invariant make them appropriate. - Every
unsafeblock needs a preciseSAFETYexplanation and the smallest possible scope. - Prefer
#[cfg]for platform-specific code. UsePath/OsStrrather than string-based path manipulation. - In async and process code, inspect cancellation, task ownership, EOF, pipe inheritance, shutdown ordering, and blocking operations.
Changes and tests
- Make surgical diffs and reuse neighboring patterns.
- Add deterministic regression tests for behavior changes. Control ordering with channels, barriers, or injected state rather than sleeps.
- Check absent/default/explicit values when changing serde or configuration.
- Keep test-only helpers and fields behind
#[cfg(test)]where possible. - Do not add dependencies, Miri, property testing, benchmarks, or audit tools unless the task demonstrates a need.
Performance
Measure before optimizing. Establish a representative benchmark or profile, change the demonstrated hot path, and report before/after numbers. Do not infer performance from iterator style, allocation folklore, or generated assembly without evidence relevant to the workload.
Validation
Discover repository commands. Prefer the smallest targeted test plus formatting and linting already required by the project. Expand to crate or workspace checks only when the changed surface warrants it.
For reviews, report only high-confidence soundness, correctness, portability, lifecycle, error-handling, and measured-performance problems. Do not impose a fixed response template.
