What is the Agent Skills specification?

It is an open format for defining agent capabilities supported by Claude Code, Cursor, VS Code, and other AI-driven development tools to ensure cross-platform compatibility.

Can I limit which tools a skill can access?

Yes, the authoring tool supports an experimental 'allowed-tools' field to restrict a skill's access to specific file, shell, or system utilities for better security and control.

How does this skill optimize token usage?

It enforces progressive disclosure, keeping core SKILL.md instructions brief while moving detailed references and scripts to separate files that are only loaded when specifically needed.

Where are skills stored within the file system?

Skills can be stored globally in ~/.claude/skills/ for use across all projects, or within a specific project directory in .claude/skills/ for project-specific capabilities.

Is validation included in the authoring process?

Yes, it utilizes tools like skills-ref and skills-check to ensure your skills meet the required YAML standards, directory structure, and formatting requirements before deployment.
