Agent model must be one of: sonnet, opus, haiku, inherit

Error

Rule Details ​

This rule enforces that the model field in agent markdown frontmatter is one of the allowed values: sonnet, opus, haiku, or inherit. Using an unrecognized model name will cause the agent framework to fail at initialization. Validation is delegated to the AgentFrontmatterSchema.shape.model Zod schema which uses the ModelNames enum. The inherit option tells the agent to use the parent conversation model.
