A local two-agent setup blocked a bad database switch using shared memory
In a local-only AI setup running on a laptop, the author used two agents and a shared memory store to enforce decision history across restarts.
One agent tried to sneak in a file that would switch the database from SQLite to Postgres. The second agent read the shared log, saw the rule saying to use SQLite, and stopped the change by quoting the exact decision it violated.
The key claim is that most people are racing to add more agents, but very few give them persistent memory that survives a restart. The author argues that this persistence is the real unlock, because a team of agents that forgets every decision after finishing is not really a team.
