xml-standards

XML tag structure standards for Claude Code agents use core tags like <role>, <instructions>, <knowledge>, <examples>, and <formatting> with defined nesting rules to ensure consistent, machine-readable agent metadata. Apply these standards during agent and command design to validate frontmatter compliance with Anthropic best practices.

Agent frontmatter requires core tags: <role>, <instructions>, <knowledge>, <examples>, and <formatting>. Specialized tags for orchestration, planners, implementers, and reviewers extend this foundation. Proper nesting and semantic attributes ensure valid, machine-parseable XML patterns across all agent definitions.

Yes. The Skill provides XML schema snippets to validate agent frontmatter and command frontmatter structures. Use these schemas to ensure your agent definitions follow correct nesting rules, semantic attributes, and character escaping guidelines compliant with Anthropic standards.

Consistent XML structure ensures agent metadata is machine-readable and maintainable across teams. Standardized tag conventions, nesting patterns, and attribute semantics enable reliable parsing, validation, and generation of agent templates and knowledge blocks following Anthropic best practices.

Agent XML requires compliant code block formatting and proper character escaping within frontmatter tags. The standards define escape sequences and nesting rules to maintain valid XML while preserving code content and metadata integrity across agent and command definitions.

Agent frontmatter and command frontmatter use the same core tags and nesting rules but structure metadata for different scopes. The Skill provides separate schema snippets for each to validate agent-level and command-level definitions consistently with Anthropic standards.
