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

.github/skills/export-api/SKILL.md

export-api is a skill for Claude Code, Codex from Azure/azure-sdk-for-rust. It costs 18 tokens per session (412 once invoked), scanned A, original, MIT.

A workflow skill that regenerates API.md files for changed Rust crates after source edits or code generation. API.md files document a crate's public programming interface.

In plain words
What is it for?
Use it after changes under the repository's SDK Rust crates, using Git changes to identify affected crates and the repository's API generator to update their artifacts.
Why use it?
It keeps generated API documentation aligned with changed Rust code and limits regeneration to affected crates.

Written for no agent in particular: nothing here depends on one.

This is Azure/azure-sdk-for-rust's own configuration. It tells Claude Code and Codex 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

export-api 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 29d 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.

What it actually says

Export API artifacts

Run this after regenerating sources or changing Rust code that can affect a crate's public API.

Default workflow

  1. Collect changed non-deleted files from Git. By default, use both staged and unstaged local changes:

    { git diff --staged --name-only --diff-filter=d; git diff --name-only --diff-filter=d; git ls-files --others --exclude-standard -- 'sdk'; } | sort -u
    
  2. If the user wants branch-based detection instead, diff against the merge base with main:

    base="$(git merge-base main HEAD)"
    git diff --name-only --diff-filter=d "$base"...HEAD | sort -u
    

    This branch-based mode only considers tracked branch changes; use the default local-change mode when untracked files should also trigger API regeneration.

  3. Assume service crates live under sdk/<service-directory>/<crate-name>. For each changed file under sdk/, derive the candidate crate directory from the first three path segments and keep it only when <crate-directory>/Cargo.toml exists.

  4. For each affected crate, run the explicit generator command from the repository root:

    cargo run --manifest-path eng/tools/generate_api/Cargo.toml -- \
      --manifest-path <crate>/Cargo.toml
    

Optional outputs

  • Pass --review to also generate api.metadata.yml, api.md.map, and api.documentation.patch.

No changed crates

If no changed files map to a crate directory under sdk/<service-directory>/<crate-name>, stop and report that no crate API artifacts need regeneration.

Validation

After generation, check the resulting api.md files in git diff and report which crates were updated.

Changes

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.
