"What can your agent do?" is two questions wearing one coat. The first is about the action space: once the agent is awake and thinking, what can it reach, call, read, and change? The second is about the trigger space: what makes it wake up in the first place? Teams conflate them constantly, and the conflation is expensive, because the two want opposite answers.

"Give the agent memory" is one of those phrases that sounds like a feature and is actually an architecture. Everyone agrees agents should remember things across sessions. Almost no one agrees on what that means — and the default implementation, a vector database that everything gets dumped into, produces agents that are confidently wrong about their own past.

The Harness Is Half the Model: Why Scaffolding Decides Performance

The most expensive misconception in applied AI is that performance lives in the model. Pick the best model, the thinking goes, and the rest is glue. So teams spend their attention on which model to call and treat everything around it — the tools, the loop, the context they assemble, the way they check the output — as plumbing.

When you build software with an AI agent day to day, the thing you run out of first isn't intelligence — it's context. The window is finite, attention inside it isn't free, and a session that starts sharp gets duller as it fills with the exhaust of the work: verbose command output, whole files read to find one function, stale documentation, the residue of three tasks ago.
