Add Knowledge Power for creating agent skills, steering files based on user intent

[manojaiconf26]

A comprehensive power for creating, updating, and maintaining agent artifacts: skills, steering files, custom agents, and hooks. Here are the details,

1. Create, update, and maintain agent skills (open standard), steering files, custom agents, and hooks.
2. Converts prompts and rules templates to skills and steering.
3. Use whenever users want to build skills, create steering files, convert existing prompts to skills, or set up agent hooks and custom agents.

I have created the power and would like to contribute.
