Description

The current documentation does not clearly show how to use asm link to link or install a skill to a specific local project directory. Users who want to add skills to a project locally (rather than globally) lack clear guidance and examples in the docs.

Reporter Context

• link/install a skill to a local of a project

Acceptance Criteria

• Documentation includes a dedicated section or example showing asm link usage for linking/installing a skill to a local project path (medium confidence)
• At least one concrete command example is provided (e.g., asm link ./my-skill -p <project> or similar) (medium confidence)
• The distinction between global and local/project-scoped skill linking is clearly explained (medium confidence)
