Each VZU agent gets a unique geometry. The wireframe is the contract. The fill is the implementation. The particles are the MCP servers the agent can call. Touch the portrait to make it respond.

The role

What ORACLE does

ORACLE is the dedicated agent behind VZU Prompts. It runs every time the operator briefs the vzu prompts capability. It owns the goal, the toolset, the memory, the audit trail.

The goal

What ORACLE is trying to achieve

"Write, version, test, and deploy production system prompts for AI agents. Run eval suites. Iterate."

The capability

What it powers

ORACLE powers the VZU Prompts capability in the VZU family.

The toolset

4 MCP actions ORACLE can call.

Every action is exposed as an MCP server (Model Context Protocol). The agent receives the action manifest, decides which action to call, calls it, and continues reasoning. The audit trail records every call.

  • mcp.prompt.write

    Write the system prompt

  • mcp.eval.run

    Run the eval suite

  • mcp.prompt.iterate

    Iterate based on eval results

  • mcp.deploy.staging

    Deploy to staging

The memory schema

What ORACLE remembers between calls.

  • → The prompt versions
  • → The eval results
  • → The deploy config

The brief

A real demo brief.

"Build the production prompt for the voice agent. Inbound, outbound, escalation, handoff. 50+ eval cases."

Below is ORACLE's actual execution trace for this brief — every step, every MCP call, every observation, every audit trail entry.

The execution trace

What ORACLE did.

Live execution trace from a recent ORACLE run. The agent was briefed: Build the production prompt for the voice agent. Inbound, outbound, escalation, handoff. 50+ eval cases.. Each line is a step. Particles flow on the rail. The audit trail streams at the bottom.
