max-function-length

Enforce a maximum number of lines per function to catch AI-generated monolithic functions

Category: Boilerplate Bloat | Tier: Pro

Why This Matters

AI tends to produce monolithic functions that handle validation, business logic, I/O, and error handling all in one block. Long functions are hard to test, hard to reuse, and hard to understand at a glance.

Bad Code

// Function is too long -- hard to understand and test
function processOrder(order) {
  // ... 80+ lines of validation, calculation,
  // database calls, email sending, logging ...
}

Good Code

// Break into focused, testable functions
function processOrder(order) {
  validateOrder(order);
  const total = calculateTotal(order);
  await saveOrder(order, total);
  await notifyCustomer(order);
}

Configuration

This rule wraps max-lines-per-function. See upstream documentation for full configuration options.
