3 common mistakes in AI agents + solutions

brush them off first -> they'll brush you off
so, fix upfront:
1. infinite tool call - resources drain even without your knowledge
agent calls tool, it fail, restart repeatedly until collapsing (Ralph Loop)
> fix: set limits + timeouts
2. forgets mid-flow - agent has amnesia
agent took a step, forgot previous, lost the point
> fix: Redis/JSON memory store with clear schema
3. silenced errors - disaster pileup
agent gets error, ignores, keeps accumulating errors, crashes.
user has no clue where to find the problem
> fix: audit log every step + rollback
state + limits + logs = successful agent structure
