SKILL.md

Comprehensive guide for building Convex backends with TypeScript. Covers function syntax, validators, schemas, queries, mutations, actions, scheduling, and file storage.

| Function Syntax | CRITICAL | New function syntax with args/returns/handler | | Validators | CRITICAL | Type-safe argument and return validation | | Schema Design | HIGH | Table definitions, indexes, system fields | | Query Patterns | HIGH | Efficient data fetching with indexes | | Mutation Patterns | MEDIUM | Database writes, patch vs replace |

| Action Patterns | MEDIUM | External API calls, Node.js runtime | | Scheduling | MEDIUM | Crons and delayed function execution | | File Storage | LOW | Blob storage and metadata |

Convex backend development guidelines. Use when writing Convex functions, schemas, queries, mutations, actions, or any backend code in a Convex project. Triggers on tasks involving Convex database operations, real-time subscriptions, file storage, or serverless functions. Source: cloudai-x/claude-workflow.
