Azure Keyvault Secrets Rust

What it does

When your agent uses it

• Tasks that involve Secrets management

Example prompts

• “keyvault secrets rust”
• “SecretClient rust”
• “get secret rust”
• “/azure-keyvault-secrets-rust”

Workflow steps

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

1. 1Use cargo add to manage dependencies, never edit Cargo.toml directly. Add and remove Rust SDK dependencies with cargo commands instead of…
2. 2Add azure_core only when importing azure_core types directly. If your code imports azure_core::http::Url…
3. 3Use DeveloperToolsCredential for local dev, ManagedIdentityCredential for production — Rust does not provide a single…
4. 4Never hardcode credentials — use environment variables or managed identity
5. 5Use ..Default::default() with #[allow(clippy::needless_update)] for model struct updates
6. 6Use ResourceExt to extract resource name/version from secret IDs
7. 7Reuse clients — SecretClient is thread-safe; create once, share across tasks
8. 8Run cargo clippy -- -D warnings when the prompt, eval, or CI expects lint-clean output

What it can do on your machine

Read from SKILL.md and the folder at commit 354361d. 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

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

  • crates.io
  • docs.rs
  • github.com

  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

Azure Keyvault Secrets Rust loads about 1.5k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 334 words of instructions outside code blocks.

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

~59

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

~1.5k

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.
