Agents That Don’t Wander
Plan, act, observe — and, hardest of all, stop.
Plan, act, observe — and, hardest of all, stop.
Anyone can put a model in a loop. The skill is getting it to stop. You will watch a toy agent finish a real multi-step task, then watch the same agent with a broken stopping condition spin until the guard trips — and then build the guards properly: goal tests, step caps, and spend caps that survive a restart.
Press play and a teacher talks you through the whole build, with a read-along transcript that highlights as it speaks.
Working, offline interactives — not screenshots. When the narration says "try it", the thing is right there.
No account, no app, no subscription. It runs from a single HTML file and will still run in ten years.
Every number is computed live on the page from inputs you can edit. Nothing is asserted that cannot be checked.
Written for builders putting a model in a loop.
Implement plan → act → observe with a real stopping condition
Set step and budget caps that persist across restarts
Recognise loops, drift, and confident nonsense at step 40
Decide what an agent may never do without a human
13 chapters, the first four free
The free preview is not a teaser: those chapters are complete, and the paid chapters are physically absent from the preview file rather than hidden behind a script.
What this hour is, how to use the page, and the interactive demo you will keep coming back to.
