FAQPage Schema

How do I validate agent YAML manifests for the Betty Framework?▼

Agent manifest validation checks agent.yaml files for schema compliance, required fields, correct name and version formats, valid reasoning_mode values, non-empty capabilities and skills lists, and ensures all referenced skills exist in the skill registry before registration.

What happens when I register an agent with agent.define?▼

Registration updates the central /registry/agents.json with validated agent entries. The Skill performs cross-reference checks against the skill registry, applies atomic updates, and returns standardized success or error responses.

Can I use agent.define to check if my skills are properly registered?▼

Yes. During agent validation, agent.define verifies that all skills referenced in your agent manifest exist in the skill registry, catching missing or misconfigured skill dependencies before registration.

What format does my agent manifest need to follow?▼

Agent manifests use YAML format (agent.yaml) with required fields including agent name, version, reasoning_mode, non-empty capabilities list, and skills list. The Skill validates structure and enum values against the schema.

How do I run agent manifest validation from the command line?▼

Use the CLI interface: python skills/agent.define/agent_define.py [path/to/agent.yaml]. The Skill processes the manifest, validates all fields and skill references, and outputs success or detailed error messages.

What errors should I expect if my agent manifest is invalid?▼

Validation fails if required fields are missing, name or version formats are incorrect, reasoning_mode is invalid, capabilities or skills lists are empty, or referenced skills don't exist in the skill registry.
