StackQL Provider Development Skill for Claude

· 3 min read

We've published a Claude Skill for StackQL provider development. It provides Claude with the context needed to help you build providers using the any-sdk library (interface used by StackQL to interact with the cloud providers).

What's in the Skill​

The skill covers the full provider development workflow:

  • Provider document structure - The provider.yaml schema and service document layout
  • OpenAPI extensions - All x-stackQL-* extensions including x-stackQL-resources, x-stackQL-config, x-stackQL-objectKey, and others
  • Resource and method definitions - How to define resources, map methods to operations, and configure responses
  • SQL verb mappings - Connecting REST operations to SELECT, INSERT, UPDATE, and DELETE
  • Authentication patterns - API keys, service accounts, OAuth, and custom auth schemes
  • Pagination handling - Request/response token configuration
  • Response processing - JSONPath extraction, transformations, and schema handling
What is a Claude Skill?

A Claude Skill is a markdown file that provides Claude with specialized knowledge for a particular domain or task. When you add a skill to your project, Claude can reference it during conversations to give more accurate, context-aware responses.

To use this skill:

  1. Download the skill file (stackql-provider-development.md)
  2. In Claude, go to your Project settings
  3. Add the skill file to your Project Knowledge

Once added, Claude will automatically apply this knowledge when you're working on StackQL provider development.

Download​

Grab the skill from the any-sdk repository:

Download stackql-provider-development.md

Usage​

With the skill loaded, you can ask Claude things like:

  • "Create a provider definition for this API"
  • "How do I map this endpoint to a SELECT operation?"
  • "What's the correct objectKey syntax for this nested response?"
  • "Help me configure pagination for this API"

Claude will have the full context of StackQL's OpenAPI extensions and provider patterns to work from.

Example​

Here's a sample interaction after loading the skill:

You: I have an API endpoint GET /users that returns {"data": {"users": [...]}}. 
     How do I set up the resource?

Claude: For that response structure, you'd configure the method like this:

methods:
  list:
    operation:
      $ref: '#/paths/~1users/get'
    response:
      mediaType: application/json
      openAPIDocKey: '200'
      objectKey: $.data.users

The objectKey uses JSONPath to extract the users array from the nested response.
