Version-aware guide for configuring and running Apollo Router for federated GraphQL supergraphs. Generates correct YAML for both Router v1.x and v2.x. Use this skill when: (1) setting up Apollo Router to run a supergraph, (2) configuring routing, headers, or CORS, (3) implementing custom plugins (Rhai scripts or coprocessors), (4) configuring telemetry (tracing, metrics, logging), (5) troubleshooting Router performance or connectivity issues.

Guide for using Apollo MCP Server to connect AI agents with GraphQL APIs. Use this skill when: (1) setting up or configuring Apollo MCP Server, (2) defining MCP tools from GraphQL operations, (3) using introspection tools (introspect, search, validate, execute), (4) troubleshooting MCP server connectivity or tool execution issues.

Guide for writing idiomatic Rust code based on Apollo GraphQL's best practices handbook. Use this skill when: (1) writing new Rust code or functions, (2) reviewing or refactoring existing Rust code, (3) deciding between borrowing vs cloning or ownership patterns, (4) implementing error handling with Result types, (5) optimizing Rust code for performance, (6) writing tests or documentation for Rust projects.

Guide for integrating REST APIs into GraphQL supergraphs using Apollo Connectors with @source and @connect directives. Use this skill when the user: (1) mentions "connectors", "Apollo Connectors", or "REST Connector", (2) wants to integrate a REST API into GraphQL, (3) references @source or @connect directives, (4) works with files containing "# Note to AI Friends: This is an Apollo Connectors schema".

Run an Apollo iOS feature request analysis for roadmap planning, or add a single new feature request to the existing analysis. Use this skill whenever someone asks to: analyze Apollo iOS feature requests, build a roadmap for Apollo iOS, research what customers are asking for in Apollo iOS, prioritize Apollo iOS work, create a stakeholder document about Apollo iOS priorities, add a new feature request to the roadmap analysis, score a specific Apollo iOS issue, or run the feature request workflow. Trigger on any mention of "Apollo iOS roadmap", "feature requests", "roadmap document", "stakeholder analysis", "what should we build next in Apollo iOS", or "add [issue #N] to the feature analysis".

Use when the user asks to "merge a stack", "merge stacked PRs", "merge PRs in order", or references a chain of PRs that depend on each other. Handles retargeting each PR to main and merging them sequentially, with admin bypass for review requirements.

Use when the user asks to "publish a release", "create a release", "cut a release", "prepare a release", "do a patch release", or "set up a release". Covers the full Apollo iOS release workflow including GitHub Actions, CHANGELOG updates, PR management, and draft release publishing across apollo-ios and apollo-ios-codegen repos.

Syncs MCP Apps documentation with the @apollo/client-ai-apps changelog. Always use this skill whenever: (1) the user wants to update or sync the mcp-apps-*.mdx docs based on a new release or version range, (2) phrases like "sync docs from version X", "update docs from changelog", "what changed since v0.x.x", "docs are out of date", or "check the changelog" appear in context of MCP Apps documentation, (3) checking whether mcp-apps-*.mdx files reflect recent releases. The changelog URL and doc file paths are pre-configured — the user only needs to provide the minimum version to sync from.

Review a GitHub pull request for a Rust codebase. Focuses on security, performance, test coverage, and Rust idioms. Runs in GitHub Actions and posts comments directly to the PR.

Guide for building React applications with Apollo Client 4.x. Use this skill when: (1) setting up Apollo Client in a React project, (2) writing GraphQL queries or mutations with hooks, (3) configuring caching or cache policies, (4) managing local state with reactive variables, (5) troubleshooting Apollo Client errors or performance issues.
