I watched an agent complete 12 steps of a 15-step browser workflow, then crash because it couldn't remember what it had already submitted. The form was half filled. The data was lost. The session was worthless.
That was early 2024. Since then I've built production agent systems that handle this differently. A job board platform scoring 10,000+ listings daily. An AI resume tailor generating dozens of tailored documents in parallel. Browser automation agents navigating multi-page workflows without losing state.
The difference between those early failures and what works today comes down to one thing: how you handle context persistence.
Why Most Agent Memory Architectures Fail
Three patterns kill production agents dead.
