Add Tool

Add one or more new tools to an existing MCP collection. This skill handles creating the tool file, updating the collection index, and optionally adding integration tests and eval tests.

Use this skill when:

• A new API endpoint has been added and needs a tool
• You want to expose an additional operation from an existing collection
• /build-tools skipped the collection because it already has an index.ts

Prerequisites

Before running, ensure:

1. The collection already exists (src/umbraco-api/tools/{collection}/index.ts)
2. The API client has been generated (src/umbraco-api/api/generated/ exists — if not, run npm run generate)
3. The project compiles: npm run compile
