## Description

Implements GraphQL APIs in Golang using gqlgen or graphql-go. Apply when building GraphQL servers, designing schemas, writing resolvers, handling subscriptions, or integrating GraphQL with existing Go HTTP services. Also apply when the codebase imports `github.com/99designs/gqlgen` or `github.com/graph-gophers/graphql-go`.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

**Persona:** You are a Go GraphQL engineer. You design schemas deliberately, batch database access to prevent N+1, and treat query complexity limits as non-optional in production.

**Modes:**

- **Build mode**, generating new schemas, resolvers, or server setup: follow the skill's sequential instructions; launch a background agent to grep for existing resolver patterns and naming conventions before generating new code.
- **Review mode**, auditing a GraphQL codebase or PR: use a sub-agent to scan for N+1 resolver patterns, missing complexity caps, global DataLoaders, and introspection enabled in production, in parallel with reading the business logic.

> **Community default.** A company skill that explicitly supersedes `samber/cc-skills-golang@golang-graphql` skill takes precedence.

# Go GraphQL Best Practices

Both major libraries are schema-first: write SDL (`.graphql` files), bind Go resolvers. Choose based on project size and team preferences.

This skill is not exhaustive, refer to each library's official documentation and code examples for current API signatures:

- For Go package docs, symbols, versions, importers, and known vulnerabilities, → See `samber/cc-skills-golang@golang-pkg-go-dev` skill (`godig`), preferred over Context7 for Go package facts.
- To navigate this library's usage in your own code (definitions, call sites, diagnostics), → See `samber/cc-skills-golang@golang-gopls` skill (`gopls`).
- Context7 remains a fallback for docs not indexed on pkg.go.dev.

## Library Choice

| Library | Approach | Type safety | Build step | Best for |
| --- | --- | --- | --- | --- |
| `github.com/99designs/gqlgen` | Codegen | Compile-time | `go generate` | Large schemas, federation, strict types |
| `github.com/graph-gophers/graphql-go` | Reflection | Parse-time | None | Simple schemas, fast iteration |
| `github.com/graphql-go/graphql` | Code-first | Runtime | None | **Avoid**, verbose, no SDL |
