Current behavior:

When running func delete without a function name, the command shows a cryptic error message that doesn't help users understand what they need to do:

rayyan@rayyan-seliya:/mnt/c/Users/RAYYAN/Desktop/func$ func delete
Error: name required

This forces users to:
1.Guess what's wrong - unclear what "name required" means
2.Look up documentation to understand the command usage
3.Still not understand the available deletion options

Proposed improvement:

Provide clear, educational guidance about how to delete functions:

Error: function name required for deletion.

Function name is required for deletion.

You can delete functions in two ways:

1. By name :
   func delete myfunction                     Delete function by name
   func delete myfunction --namespace apps    Delete from specific namespace

2. By path :
   func delete --path /path/to/function       Delete function at specific path

Examples:
   func delete myfunction                     Delete 'myfunction' from cluster
   func delete myfunction --namespace prod    Delete from 'prod' namespace
   func delete --path ./myfunction            Delete function at path
  
For more options, run 'func delete --help'

Solution:
Implement a 2-layer error system that provides both technical error information and user-friendly guidance.

Expected Workflow:

According to the official documentation, building requires:

1,.By name : func delete <function-name>

2.By path : func delete --path <path>

The improved error message guides users through both deletion methods with clear examples.

User Impact:

• Current: Cryptic error → confusion → need to look up documentation
• Improved:Immediate understanding → better user experience
