What are the core XML tags required for every agent?

Every agent should include , , , , and tags to ensure identity clarity and consistent behavioral constraints.

Does this skill handle character escaping?

Yes, it includes guidelines for escaping characters like , and & in XML attribute values and text nodes to prevent parsing errors during agent execution.

How does this skill help with orchestrator agents?

It provides specialized tags like and to define tool permissions and hand-off logic between different specialized agents.

Why should I follow these XML standards?

Following these standards aligns your prompts with Anthropic's recommended structures, leading to more predictable performance and better tool utilization by Claude.

Can I use code blocks inside these XML tags?

Yes, the skill provides specific syntax rules for nesting code blocks inside templates, ensuring the language identifier is placed correctly directly under the tag.
