- Schema/manifest (attribute-based taxonomies; agent capability records)
- core_mechanism
- OASF defines a standardized, attribute-based schema for agent capabilities, interactions, and metadata; agents publish OASF records so other agents and directories can discover and understand them across platforms. It functions as a 'DNS for agents' and underpins AGNTCY's Agent Discovery.

- Publishing a standardized, discoverable description of an agent's capabilities for cross-platform multi-agent systems.
- when_to_use
- When you are building on the AGNTCY 'Internet of Agents' stack and need a common capability schema for agent discovery.
- when_not_to_use
- When you have committed to A2A Agent Cards or only need a single agent to call tools (use MCP).
