Agent Skills: Umbraco Content Delivery API

Umbraco Content Delivery API

Purpose

Guide Claude to use the Umbraco Content Delivery API endpoints correctly and efficiently.

Scope

• Included: endpoint selection, path vs id usage, query parameters, headers, preview, localization.
• Excluded: backoffice mutations, schema changes, or MCP administrative operations.

When to Use

• You need to read content via the Delivery API.
• You need to craft requests with filters, expansion, or paging.

When Not to Use

• You need to create or update content.
• You need to manage content types or media in the backoffice.

Endpoint Strategy

• Choose the smallest endpoint that returns the needed data.
• Prefer single-item endpoints for known content items.
• Use list and query endpoints for discovery and pagination.
• See references/request-recipes.md for common request shapes.

Request Policy

• Use Start-Item for multi-site or root-scoped queries.
• Use Accept-Language only when requesting by id.
• Use Preview: true with Api-Key for draft content.
• Limit payloads with fields and use expand only when needed.

Response Format

• Provide a canonical request shape with headers and query parameters.
• Explain the minimum required inputs and expected response types.

Examples

• Get a content item by id.
• Get a content item by path.
• Fetch children of a node with paging.
• Filter by content type and sort by update date.
• Fetch a draft item with preview and API key.
