Create a markdown file in `.claude/commands/` with YAML frontmatter defining name, description, arguments, and model. The frontmatter must specify commandType, argument hints, and tool permissions to match the Claude Slash Command schema and ensure proper validation.

Slash commands require name, description, commandType, and model fields in YAML frontmatter. Optional fields include arguments with hints, tools, and output formatting. Each field must follow the schema to pass validation and work reliably across project files.

Define frontmatter templates and validation rules, then create commands using the standardized structure. This Skill provides schema guidance and best practices to ensure all team commands follow consistent patterns, tool permissions, and argument formatting.

Common errors include incorrect YAML syntax, missing required frontmatter fields, malformed argument hints, and inconsistent commandType values. Validation against the Claude Slash Command schema catches these before deployment and prevents runtime failures.

Yes. Create a `/code-review` command with frontmatter specifying tools for file analysis, output formatting for review results, and argument hints for code paths. This Skill guides proper structure and permissions to build working automation commands.
