# Find Package Skill

Some SDK packages in this monorepo have **package-specific skills** — tribal
knowledge (architecture, data flows, type mappings, pitfalls) that prevents
common mistakes. Before modifying any SDK package, check whether a skill exists
for it using the steps below.

## How to Discover Package Skills

1. **Determine the package directory.** If you already know the file path you're
   modifying, extract the package directory from it (e.g., a file at
   `sdk/search/Azure.Search.Documents/src/SearchClient.cs` belongs to the package
   at `sdk/search/Azure.Search.Documents/`). If you only have a package name,
   search for a matching directory under `sdk/` or use `.github/CODEOWNERS` path
   patterns to resolve the service area.

2. **Check for a `.github/skills/` directory** inside the package directory. For
   example, check whether `sdk/search/Azure.Search.Documents/.github/skills/`
   exists.

3. **If it exists**, read every `SKILL.md` found under that directory. If a
   `references/` subdirectory exists next to a `SKILL.md`, read all files in it
   too for additional context.

4. **If no `.github/skills/` directory exists** for the package, no
   package-specific skill has been created yet — proceed normally.
