Supervisor Agent

Concept & How It Works

    Why Does It Exist?

    One LLM can't specialize in everything. A supervisor provides the management layer that routes work to experts and maintains global context.

    Real-World Analogy

    The supervisor is a project manager who doesn't write code but knows which engineer to assign, tracks deadlines, and merges pull requests into a shippable release.

    What is Supervisor Agent?

    Example

    Scenario

    Supervisor receives 'Write competitive analysis' → delegates market data to Research Agent, comparison table to Analyst Agent, merges into final doc.

    Solution

    In Multi-Agent Systems, apply Supervisor Agent to this scenario: Supervisor receives 'Write competitive analysis' → delegates market data to Research Agent, comparison table to Analyst Agent, merges into final doc. Identify the inputs, run the technique, validate the output, and note one thing you would monitor in production.

    Practice Task

    Do this before moving to the next module — reading alone is not enough.

    Open the Code Walkthrough below and run it locally. Change one parameter related to Supervisor Agent (e.g. model, temperature, top_k, or tool name), observe the difference in output, and write 2–3 sentences explaining what changed.

    Code Walkthrough

    Highlighted lines show where Supervisor Agent happens in the code.
