ThePrimeagen visualizes program state machines to regain control in the agent era
samgoodwin89 · x · 2026-11-14
Well-known developer ThePrimeagen highlights a core pain of the agent era: the gap between what you think should be done and what the agent actually does — too much control is lost. His idea: visualize the state machine of your program so developers can see and steer behavior again.
Inspired by this, someone built domain-devtools, a developer tool for Alchemy Domain aggregates (19 stars on GitHub) that generates Mermaid command diagrams and aggregate state overviews from source, letting you inspect contracts, decisions, events, and evolution.
