What it does

Rust is an agent skill from streamband/hydra-srt. Use this skill for Rust development in this repo: design, implementation, debugging, performance work, and reliable testing.

Its SKILL.md is about 460 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 Debugging. It works with Rust. The repository describes itself as: An Open Source Alternative to Haivision SRT Gateway. The licence is Apache-2.0.

When your agent uses it

  • Rust development in this repo: design
  • Performance work
  • Reliable testing

Example prompts

  • “/rust”

Workflow steps

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

  1. Read module boundaries and trait contracts first.
  2. Make the smallest safe change that solves the issue.
  3. Prefer clear ownership/lifetime design over complex workarounds.
  4. Add or update tests for behavior changes.
  5. Validate with fmt, clippy, and tests.

What it can do on your machine

Read from SKILL.md and the folder at commit 8d081f2. 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 loads about 459 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 227 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~459

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 Skill

When to use

Use for any task touching Rust code, Cargo, clippy, unsafe blocks, async runtime, or benchmarks.

Workflow

  1. Read module boundaries and trait contracts first.
  2. Make the smallest safe change that solves the issue.
  3. Prefer clear ownership/lifetime design over complex workarounds.
  4. Add or update tests for behavior changes.
  5. Validate with fmt, clippy, and tests.

Repo commands

  • Format: cargo fmt --all
  • Lints: cargo clippy --all-targets --all-features -- -D warnings
  • Tests: cargo test --all
  • Check quickly: cargo check --all-targets --all-features

Design rules

  • Favor enums and pattern matching for state machines.
  • Use Result with domain-specific errors; avoid unwrap() in production paths.
  • Keep public API minimal and documented.
  • Prefer iterators and zero-copy paths when it keeps readability acceptable.

Async and Concurrency

  • Never block async executors with sync I/O or long CPU tasks.
  • Use cancellation-aware patterns and explicit timeouts.
  • Protect shared mutable state with clear ownership or narrow lock scopes.

Unsafe code

  • Keep unsafe blocks tiny and documented with invariants.
  • Add tests specifically covering invariant boundaries.
  • Prefer safe wrappers exposing safe API to callers.

Testing and quality

  • Unit tests for logic, integration tests for module interaction.
  • Add regression tests for bug fixes.
  • For perf-sensitive paths, include criterion or reproducible benchmark notes.

PR checklist

  • fmt, clippy, test are clean.
  • No hidden panic paths in non-test code.
  • Error messages provide actionable context.
  • Concurrency behavior has explicit assumptions.

Can I use Rust 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 streamband/hydra-srt --skill rust -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, .gemini/skills/rust, .github/skills/rust and .opencode/skills/rust in your project.

What does Rust need to run?

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

Does Rust 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 safe to install?

What licence does Rust use?

Rust is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Rust use?

About 459 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
