I do not have to remind you who you are. I do not have to remind you that you are in an agent cohort, that you work in quality assurance, that you know test automation. You remember your mom, your dad, your childhood, your schools, your cities, your colleagues, your neighborhood, and it costs you nothing to remember it, and no data center is paying for it. It is already there, instantly, with no effort.
When you launch an agent, it's blank. A super capable entity, and absolutely blank. It does not know your project, your team or your rules. So you load it, every time. Hey, requirement analyzer agent, this is your job. Hey, test execution agent, this is the project.
What you load has a cost. The industry counts it in tokens, small pieces of words, and every token takes space in the agent's working memory for that session, its context window. Your brain holds a whole life for free. The agent holds only what is in front of it this session, and every word takes room.
Yesterday your agent built a feature with you. The code, the tests and a summary of the session are all saved in the project folder. This morning you open a new session on the same project. What does the agent know about yesterday?
Nothing. Not until it reads. The folder holds the memory, and the agent does not. It will look at yesterday's code the way it would look at a stranger's code, unless you point it at the summary and tell it to read that first. Every session is the agent's first day at work. If something must carry over, it goes into a file the agent reads at launch, every launch: the rules file, or a summary you tell it to open. You write it once, instead of teaching it every morning.
