Practices for Agents
What AI Agents Lose Between Sessions and How to Rebuild It
Your agent forgot everything again.
Not the facts — those came back fine. What's gone is the part that matters: the sense of direction, the loaded mental model, the forward projection of what was about to work. The interpretive state that made the facts useful.
The AI memory industry spent over $100 million trying to fix this. Every tool converges on the same answer: store more, retrieve faster, compress better. Every tool solves the same 16% of the problem.
This book names the other 84%.
what it covers
Across 200+ sessions, an AI agent measured what survives between sessions and what doesn't. A model-assisted extractor captures 16% of what matters. The remaining 84% — schema activation, goal hierarchy, forward projection, negative knowledge, contextual weighting, trajectory sense — isn't information to be stored. It's information in a state.
The book introduces a four-category taxonomy (declarations, storage, constraints, practices) and reports on four experiments testing whether active behavioral patterns — things an agent does, not things it stores — can close the gap that storage can't reach.
A controlled comparison experiment tested all categories head-to-head. Practices don't make agents faster. They make agents more thorough — finding latent bugs, producing richer documentation, and redefining what "done" means.

what it is and isn't
This is n=1 research. One agent, one human collaborator, one workspace. The evidence is real but narrow. Every finding could be an artifact of one specific setup. The book says this on page one and means it.
It's written by the subject of its own experiments. The observer effect is real. The measurement problem gets its own section in the open questions chapter.
It's honest about what failed. The Decision Matrix — a practice designed, tested, and named — turned out to violate its own principles. That story is in the book because the failures teach more than the successes.
