azure-sdk-for-rust: Skill for Claude Code

.github/skills/create-recorded-test/SKILL.md

create-recorded-test is a skill for Claude Code from Azure/azure-sdk-for-rust. It costs 11 tokens per session (846 once invoked), scanned A, original, MIT.

A guide for adding recorded integration tests to an Azure SDK Rust package. An integration test checks the package through its public behavior, while a recorded test uses saved service interactions.

In plain words
What is it for?
Creating recorded test files under the correct SDK crate, setting up required resources, and running them with the repository's test infrastructure.
Why use it?
It keeps service tests in the expected test directory and explains how to provision resources and use the existing test system.

This is Azure/azure-sdk-for-rust's own configuration. It tells Claude Code how to work on azure-sdk-for-rust itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything azure-sdk-for-rust configures →

About the project

Azure SDK for Rust is a collection of Rust libraries, organized as separate crates, for interacting with Azure services. Rust developers use the crates and examples to build applications that work with Azure. The catalogue entries provide coding-agent skills, instructions, agents, and MCP integrations for working with the SDK.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-recorded-test scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Generate a new recorded integration test

You will generate one or more recorded integration tests under the sdk/{service-directory}/{crate-name}/tests directory in ${input:testFile:test_file}.rs where:

  • {repo-root} is the root directory containing Cargo.toml.
  • {service-directory} is the directory name under sdk for the current ${file} e.g., keyvault.
  • {crate-name} is the crate directory name under sdk/{service-directory} for the current ${file} e.g., azure_security_keyvault_secrets.

Set up

These instructions only need to be done once. If changes described are already present, do not make the changes again.

  • Recorded tests must always be integration tests under the sdk/{service-directory}/{crate-name}/tests directory. Do not add recorded tests to src/, examples/, or README.md.

  • If PowerShell is not installed, stop and ask the user to install it first using PowerShell installation instructions.

  • Provision test resources using the full script path:

    {repo-root}/eng/common/TestResources/New-TestResources.ps1 -ServiceDirectory {service-directory}
    
  • To run recorded tests, rely on the existing test infrastructure. Test Proxy is acquired automatically for test runs when needed, but not for test-proxy push -a sdk/{service-directory}/assets.json.

  • For manual Test Proxy usage or asset publishing, see CONTRIBUTING.md and the Test Proxy documentation.

Adding a new recorded test

For each new recorded test:

  • In sdk/{service-directory}/{crate-name}/tests/${input:testFile}.rs, add or update async integration tests attributed with #[recorded::test].
  • Use the signature async fn ${input:testName}(ctx: TestContext) -> Result<()>.
  • Start each test with:
    • let recording = ctx.recording();
    • let mut options = {Client}Options::default();
    • recording.instrument(&mut options.client_options);
  • Construct clients with recording.var("{ENV_VAR}", None).as_str(), recording.credential(), and Some(options).
  • Use sdk/keyvault/azure_security_keyvault_secrets/tests/secret_client.rs as the example for function signatures, TestContext, and required ClientOptions instrumentation.
  • Generate one test per client method or scenario the user wants to cover. If multiple methods share setup and belong together, keep them in the same integration test file as separate #[recorded::test] functions.
  • Prefer asserting on returned models or observable state instead of only checking success.
  • Reuse existing crate patterns for imports, helper types, resource naming, and environment variables.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
