Use when working with GraphQL, DataLoader, TypeScript, API Security.\ntriggers:\n  - graphql n1 prevention\n  - graphql\n  - dataloader\n---\n\n# GraphQL Schema Validation, Complexity Limits & DataLoader Skill\n\n## 1. When to Use This Skill\nLoad `skill-graphql-n1-prevention` whenever an engineering or operations task involves **GraphQL, DataLoader, TypeScript, API Security**. Specifically:\n- Eliminate N+1 database queries in GraphQL resolvers using request-scoped DataLoaders, enforce query depth/cost limits, and validate persisted operations.\n- Designing, reviewing, or debugging production configurations without guesswork or deprecated flags.\n- Running deterministic pre-flight and post-execution verification checks before reporting completion.\n\n## 2. Prerequisites & Required Environment\n- **Target Stack:** GraphQL, DataLoader, TypeScript, API Security\n- **Permissions:** Read-only inspection by default; ask for explicit confirmation before executing destructive mutations or production deployments.\n- **Reference Repository:** `https://github.com/graphql/dataloader`\n\n## 3. Step-by-Step Execution Playbook\n1. **Context & Configuration Discovery:**\n   Inspect existing project manifests (`package.json`, `wrangler.jsonc`, schema files, or environment declarations) before proposing changes. Never overwrite existing bindings or credentials blindly.\n2. **Deterministic Implementation:**\n   Apply the canonical patterns for **GraphQL**:\n   - Enforce strict schema/type validation at every external boundary.\n   - Include explicit error handling, structured logging, and idempotency keys on all mutating calls.\n   - Keep secrets in environment variables or secret stores—never hardcode tokens in source files.\n3. **Verification & Regression Gate:**\n   Run the verification commands below and inspect both exit codes and output payloads before marking the task complete.\n\n## 4. Reference Commands & CLI Workflow\n```bash\nnpx graphql-inspector validate schema.graphql operations.graphql\n```\n\n## 5. Edge Cases & Anti-Hallucination Guardrails\n- **Zero Unverified Claims:** Never claim a deployment, migration, or API call succeeded without inspecting the command output or HTTP status code.\n- **Rollback Readiness:** Always record the previous state or migration version so changes can be reverted cleanly if downstream health checks fail.\n",
  "starter_prompt": "Load the GraphQL Schema Validation, Complexity Limits & DataLoader Skill (skill-graphql-n1-prevention) playbook. First inspect our current configuration and codebase for GraphQL, DataLoader, TypeScript, API Security. Then propose a concrete, step-by-step implementation plan following the skill-graphql-n1-prevention guardrails, run the non-destructive verification commands (npx graphql-inspector validate schema.graphql operations.graphql), and summarize any findings, risks, or required environment variables before making production changes.",
