Rust Testing

What it does

When your agent uses it

• Adding unit tests
• Integration tests
• Data-driven cases
• Coverage-oriented test scenarios

Example prompts

• “Use the rust-testing skill to pattern for Rust testing in Axone CosmWasm contracts. An agent skill from axone-protocol/contracts”
• “/rust-testing”

Workflow steps

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

1. 1Isolate tests. Each test should set up its own environment.
2. 2Test contract behavior, not framework internals.
3. 3Assert exact errors when possible.
4. 4Cover edge cases such as zero values, empty strings, and upper bounds.
5. 5Prefer descriptive test names without a test_ prefix.
6. 6Use tuple-driven cases for simple matrices and structs only when the case shape needs named fields.

What it can do on your machine

Read from SKILL.md and the folder at commit 02724f3. 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 501 tokens when it runs, and up to ~1.8k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 158 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~43

When it runs · the whole SKILL.md, loaded when a task matches

~501

With references · SKILL.md plus every file in references/, read only if the agent opens them

~1.8k

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

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.
