How do I check if my template exceeds AWS resource limits?

You can use the `check_template_compliance` tool by providing your template size in KB and the total resource count.

What are the standard limits for stack outputs and parameters?

The standard limit for both outputs and parameters is 200 per stack. You can verify this using `calculate_stack_capacities`.

Can I check limits for Stack Sets?

Yes, use the `evaluate_stack_set_limits` tool to determine the maximum number of stack sets and instances per set allowed for your account.
