SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Live interactive trajectory exploration and improvement of agent behavior in the Varro playground, enabling researchers to probe observations and actions as they unfold and to propose concrete improvements to tools, prompts, docs, and UI-as-agent-tools.

Core Features & Use Cases

  • Live CLI-based probing to diagnose agent behavior in the Varro playground.
  • Inspect trajectory artifacts (turns, tool_calls, images) and associated observations to trace decisions and failures.
  • Propose concrete improvements to prompts, tools, docs, and UI components, and write findings to data/trajectory/{user_id}/{chat_id}/findings.md.
  • Support structured exploration workflows with a clear rubric and validation steps.

Quick Start

Launch a CLI probe by running uv run python -m varro.playground.cli and begin a subject exploration.

FAQPage Schema
How do I debug agent trajectories interactively in the Varro playground?

To debug agent trajectories interactively in the Varro playground, launch a CLI probe by running uv run python -m varro.playground.cli to inspect live observations and trace decisions.

What is interactive trajectory analysis for agent behavior?

Interactive trajectory analysis is the process of probing live observations and trajectory artifacts to root-cause agent failures and propose concrete improvements to prompts and tools.

How do I diagnose agent decisions using trajectory artifacts?

You diagnose agent decisions by inspecting trajectory artifacts including turns, tool_calls, and images via CLI-based probes to trace exactly where and why the agent failed.

How do I generate a findings report for prompt improvement?

You generate a findings report for prompt improvement by proposing changes during exploration, which the system writes to data/trajectory/{user_id}/{chat_id}/findings.md.

Can I propose improvements to UI components during agent trajectory exploration?

Yes, you can propose concrete improvements to UI components, as well as prompts and docs, while probing agent behavior in the Varro playground.

Do I need any external dependencies to run CLI probes for trajectory exploration?

No external dependencies are required to run CLI probes for trajectory exploration, as the Skill operates independently to generate trajectory data under data/trajectory.
