Available Skills

apollo-connectors

Write Apollo Connectors schemas to integrate REST APIs into GraphQL.

Install:

npx skills add apollographql/skills@apollo-connectors

Use when:

• Connecting REST APIs to a GraphQL supergraph
• Writing @source and @connect directives
• Implementing entity resolvers with batching
• Validating connector schemas with rover

Categories covered:

• Selection mapping grammar
• HTTP methods and headers
• Variable interpolation ($args, $this, $config)
• Entity patterns and @key directives
• Batch requests with @listSize

Examples:

• "Connect my REST API to my GraphQL schema"

apollo-federation

Author Apollo Federation subgraph schemas with entities, sharing, and cross-subgraph field resolution.

Install:

npx skills add apollographql/skills --skill apollo-federation

Use when:

• Creating new subgraph schemas for a federated supergraph
• Defining or modifying entities with @key
• Sharing types/fields across subgraphs with @shareable
• Working with federation directives (@external, @requires, @provides, @override)
• Troubleshooting composition errors

Categories covered:

• Entity definition and @key patterns (compound, multiple, differing)
• Reference resolvers and computed fields
• Value types with @shareable
• Field migration with @override (including progressive rollout)
• Entity interfaces with @interfaceObject
• Common composition errors and fixes

Examples:

• "Create a federated subgraph for my products service"
• "Add a computed field that requires data from another subgraph"
• "Migrate this field from one subgraph to another"
