Agents should be able to describe what capabilities and functionalities they have

Seeing a list of Agents and their actions isn't always enough information to tell me what the agent is capable of doing. It should be able to answer questions about it's capabilities or give a quick summary. This should be a standard capability between all agents

No files, tests, or entry points are identified in the issue. Start by tracing how agents and their actions are represented, then define the shared capability response and verify that every agent can summarize its capabilities and functionality.
