## What it does

The skill kicks in when Rust code has to pull a password, API key or connection string out of Azure Key Vault. It ships `SecretClient` examples: fetch a secret, set a new one, update its properties, delete it, and walk the list with pagination. Error handling for a missing secret gets its own section.

The agent is told to stick to the official `azure_security_keyvault_secrets` crate published by the azure-sdk crates.io user, not community wrappers. Dependencies go in through `cargo add`; hand-editing `Cargo.toml` is off the table. Add `azure_core` to the manifest only when you import its types directly.

You need `AZURE_KEYVAULT_URL` set to the vault address. Rust has no `DefaultAzureCredential`, so local work uses `DeveloperToolsCredential` and production uses `ManagedIdentityCredential`. The Entra ID principal needs the `Key Vault Secrets User` role to read, or `Key Vault Secrets Officer` for full management.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill azure-keyvault-secrets-rust -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/azure-keyvault-secrets-rust/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/azure-keyvault-secrets-rust/

### Codex

**Manually: put the files in place**
- File: `.agents/skills/azure-keyvault-secrets-rust/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/azure-keyvault-secrets-rust/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills azure-keyvault-secrets-rust
```

2. **Manually: put the files in place**
- File: `.github/skills/azure-keyvault-secrets-rust/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/azure-sdk-rust/skills/azure-keyvault-secrets-rust
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/azure-keyvault-secrets-rust/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/microsoft/skills/tree/HEAD/.github/plugins/azure-sdk-rust/skills/azure-keyvault-secrets-rust/SKILL.md

## When to use it
- read a password or API key from Azure Key Vault in a Rust app
- store a new secret and read back its version
- update tags and content type on an existing secret
- page through every secret in a vault
- handle the error when a secret is missing or access is denied

## Example prompts
- show me how to fetch a secret from Azure Key Vault with SecretClient
- add secret writing to this project using azure_security_keyvault_secrets
- rewrite this secret listing with a Pager and try_next

# Azure Key Vault Secrets library for Rust

Secure storage for passwords, API keys, and connection strings.

Use this skill when:

- An app needs to store or retrieve secrets from Azure Key Vault in Rust
- You need to set, get, update, or delete secrets
- You need to list secret properties with pagination
- You need error handling for missing secrets

> **IMPORTANT:** Only use the official `azure_security_keyvault_secrets` crate published by the [azure-sdk](https://crates.io/users/azure-sdk) crates.io user. Do NOT use unofficial or community crates. Official crates use underscores in names and none have version 0.21.0.

## Installation

```sh
cargo add azure_security_keyvault_secrets azure_identity tokio futures
```

> If your code uses `azure_core` types directly, add `azure_core` to `Cargo.toml`. If you only use `azure_security_keyvault_secrets` re-exports, direct `azure_core` dependency is optional.

## Environment Variables

```bash
AZURE_KEYVAULT_URL=https://<vault-name>.vault.azure.net/ # Required for all operations
```

## Authentication

Rust Azure SDK code must not use `DefaultAzureCredential`. The Rust identity crate does not provide that type.

```rust
use azure_identity::DeveloperToolsCredential;
use azure_security_keyvault_secrets::SecretClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Local dev: DeveloperToolsCredential. Production: use ManagedIdentityCredential.
    let credential = DeveloperToolsCredential::new(None)?;
    let client = SecretClient::new(
        "https://<vault-name>.vault.azure.net/",
        credential.clone(),
        None,
    )?;

    let secret = client
        .get_secret("secret-name", None)
        .await?
        .into_model()?;
    println!("Secret: {:?}", secret.value);
    Ok(())
}
```

Prefer the crate README/examples when checking whether pagers yield items directly and how `ResourceExt` is used in public examples.

## Core Workflow

### Set Secret

```rust
use azure_security_keyvault_secrets::{models::SetSecretParameters, ResourceExt};

let params = SetSecretParameters {
    value: Some("secret-value".into()),
    ..Default::default()
};

let secret = client
    .set_secret("secret-name", params.try_into()?, None)
    .await?
    .into_model()?;

println!(
    "Name: {:?}, Version: {:?}",
    secret.resource_id()?.name,
    secret.resource_id()?.version
);
```

### Update Secret Properties

```rust
use azure_security_keyvault_secrets::models::UpdateSecretPropertiesParameters;
use std::collections::HashMap;

#[allow(clippy::needless_update)]
let params = UpdateSecretPropertiesParameters {
    content_type: Some("text/plain".into()),
    tags: Some(HashMap::from_iter(vec![(
