General TypeScript Rules

  message: "Use PascalCase for class and interface names for consistency."
EdgeDB-js Rules

rules:
- description: "Prefer using edgeql-js query builder over raw EdgeQL strings"
  regex: "client\.query\(`"
  replace: "e.<query\_method>()"
  message: "Use the edgeql-js query builder for type-safe and readable queries."
- description: "Use generated edgeql-js types for better type safety"
  regex: "any"
  replace: "<GeneratedEdgeDBType>"
  message: "Replace 'any' with specific EdgeDB types generated by edgeql-js."
Hono Framework Rules
match: "*.ts"
rules:
- description: "Use Hono's request handler typing for type-safe route handlers"
  regex: "async function (req, res)"
  replace: "async (c: Context) =>"

File Structure Rules for Atomic Files
match: "*.ts"

- description: "Ensure file names reflect their content and purpose (e.g., getUser.ts, createUserRoute.ts)"
  regex: "(queries|routes)\/(.*)\.(ts|js)"
  replace: "$1/$2.$3"
  message: "Follow the naming convention: queries should describe the action (e.g., getUser.ts), and routes should reflect the endpoint or handler (e.g., createUserRoute.ts)."
Enforce Documentation and Comments

- description: "Ensure all functions have JSDoc comments"
  regex: "function [a-zA-Z_][a-zA-Z0-9_]$.$\s*{"
