Why should I use specialized tags for Orchestrators or Planners?

Using specialized tags helps Claude understand its specific functional scope, defining allowed tools, delegation rules, and planning methodologies, which leads to more accurate and efficient outputs.

What are Claude Code XML Standards?

They are standardized tag structures, such as , , and , used to define the behavior, identity, and constraints of Claude Code agents and commands for better reliability.

Does this skill follow Anthropic's recommended practices?

Yes, these patterns are specifically designed to follow Anthropic's best practices for long-context models, ensuring structured prompting and clear hierarchy.

How do I handle code blocks inside these XML tags?

The skill provides specific nesting rules, such as placing opening code fences directly under the tag and using proper character escaping for attributes to maintain XML integrity.
