Memory & Tool Use

How agents remember and how they reach into the world. The two skills that separate "demo" from "shipped".

    Lab task

    A chat that uses ALL three memory tiers — show what gets stored where.

    Checkpoint

    You can place any new fact in the right memory tier in <5 seconds.

What you'll be able to do
  • Pick the right memory pattern for the task (chat / persistent / vectorised).
  • Wire an agent to MCP tools without leaking secrets.
  • Handle tool failures gracefully — retries, fallbacks, give-up branches.
