When should I use the skill-design plugin?

Use it when you need to create reusable agent capabilities, package repeated workflows, or build skills that require high security and evaluation standards.

Is this compatible with the Agent Skills Specification?

Yes, the workflow includes a specific validation step (Step 9) to ensure compliance with the official Agent Skills Specification.

What is the Skill Design Loop (SDL)?

SDL is a 10-step systematic methodology for designing maintainable, secure, and production-grade agent skills for AI assistants like Claude.

What is progressive disclosure in this context?

It is an architecture that keeps the main SKILL.md file lean and focused while linking to deeper documentation in a references folder, preventing context window bloat for the AI.

How does this help with security?

It includes a dedicated step for security hardening, defining trust boundaries, forbidden actions, and required user confirmations for destructive operations.
