What it does

Rust Systems is an agent skill from WrongStack/WrongStack. Build and upgrade Rust services, CLI and systems components with explicit error, async and resource contracts. Use when working on Rust ownership, concurrency, serialization or unsafe boundaries; preserve MSRV and edition compatibility unless their migration is requested.

Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Rust. The repository describes itself as: An AI coding agent that reads your code, edits files, runs commands, and reasons through bugs — across a terminal REPL, a full-screen TUI, and a browser UI, while you keep your… The licence is MIT.

When your agent uses it

  • Working on Rust ownership
  • Unsafe boundaries
  • Preserve MSRV and edition compatibility unless their migration is requested

Example prompts

  • “/rust-systems”

Requirements

  • Docker

Workflow steps

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

  1. Model errors and finite states explicitly; avoid panics for ordinary input/I/O failures.
  2. Preserve borrowing/ownership invariants at async and callback boundaries, not merely compiler acceptance.
  3. Bound task concurrency and blocking work; use the existing runtime scheduling and cancellation model.
  4. Check serialization/input at trust boundaries and separate private state from public output.
  5. For unsafe code, document the exact safety invariant and inspect each caller; no blanket safety comments.
  6. Drop/release behavior and persistent data recovery are separate; RAII does not guarantee a successful external commit.

What it can do on your machine

Read from SKILL.md and the folder at commit a744bdc. 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

    Links to these hosts (documentation or services it may open):

    • static.rust-lang.org
    • doc.rust-lang.org

    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 Systems loads about 771 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 270 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~771

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 Systems

Selection card

  • Task: Implement Rust ownership, error and async boundaries. / TR: Rust sahiplik, hata ve async sınırları uygula.
  • Start: Locate the endpoint, schema, authentication boundary and caller.
  • Finish: apply the acceptance checks below; report observed results and unresolved constraints.

Overview

Build and upgrade Rust services, CLI and systems components with explicit error, async and resource contracts.

Checked stable Rust target: 1.99.0 on 2026-10-09. Verify rust-version, edition, workspace/toolchain pins and crate support before upgrading.

Rules

  1. Model errors and finite states explicitly; avoid panics for ordinary input/I/O failures.
  2. Preserve borrowing/ownership invariants at async and callback boundaries, not merely compiler acceptance.
  3. Bound task concurrency and blocking work; use the existing runtime scheduling and cancellation model.
  4. Check serialization/input at trust boundaries and separate private state from public output.
  5. For unsafe code, document the exact safety invariant and inspect each caller; no blanket safety comments.
  6. Drop/release behavior and persistent data recovery are separate; RAII does not guarantee a successful external commit.

Workflow

  1. Inspect workspace, features, toolchain/MSRV and current crate APIs.
  2. Verify latest compatible stable targets and migration deltas.
  3. Implement the feature with typed states and clear ownership.
  4. Test error/cancel/restart behavior and boundary inputs; use configured sanitizers/Miri where relevant.
  5. Run fmt/clippy/test/build through project commands and validate the deliverable.

Before returning

Toolchain/MSRV changes explicit; ownership/error contracts checked; unsafe claims supported; actual tests/build reported.
