Execution and Scope
Watching an agent work its task list — and keeping the diff inside the brief.
During execution the agent works through its task list — editing, running commands, checking items off as evidence accumulates. The failure mode to watch is scope creep: the agent notices a tangential problem and 'helpfully' fixes it, blowing up the diff. A well-run agent flags out-of-scope findings in the walkthrough instead of silently fixing them — and that rule is exactly the kind of thing you make durable in the knowledge base (Lesson 20... you'll get there).
