Alongside it, the **Tools** card lists every tool the agent called during that version's traces - name, description, and JSON schema, captured directly from `gen_ai.tool.*` / function-call attributes, or a "schema not captured" placeholder if the schema wasn't emitted. Because both cards are captured from live trace data rather than a static registry, the system prompt and tool list always match what the agent actually ran - not a hand-maintained description of it. If an agent hasn't emitted `gen_ai.system_instructions` or tool definitions yet, both cards show an empty state explaining what's missing. ## Version scoping Definition always shows one specific version's snapshot - whichever is selected in the header, or the latest version if you haven't picked one. It never shows aggregate or all-versions data, since a system prompt and tool list only make sense as a single point-in-time capture. *** How versions are fingerprinted, and how selecting one scopes every tab
