Run TypeScript type checking after file edits and immediately flag type errors before moving on. Uses Cursor hooks for automatic enforcement.

Auto Type Checking Catch type errors immediately after every edit instead of discovering them at build time. Manual Workflow After editing a TypeScript file, run: If errors appear, fix them before moving on. Automated with Cursor Hooks Add to .cursor/hooks.json to run automatically after every file edit: Create .cursor/hooks/check types.sh : What to Check When type errors appear: 1. Missing imports : Cannot find name 'X' → add the import 2. Type mismatches : Type 'string' is not assignable to type 'number' → fix the type or the value 3. Missing properties : Property 'x' does not exist on type 'Y' → add the property to the interface or fix the access 4. Null safety : Object is possibly 'null' → add null check or optional chaining 5. Generic constraints : Type 'X' does not satisfy the constraint 'Y' → fix the generic parameter Tips Use noEmit to type check without producing output files For large projects, tsc can be slow — consider incremental or running only on changed files If using path aliases, ensure tsconfig.json paths are configured correctly For monorepos, run tsc from the package root, not the workspace root Pair with grinding until pass for a full "fix until clean" loop
