record

Keep durable architecture decisions and product specs in sync with the work happening in the conversation. AUTO-INVOKE when a request establishes or changes a long-lived architectural boundary, public contract, data ownership rule, operational invariant, or repo-wide convention with meaningful alternatives. Also invoke on explicit triggers: "record this", "create an ADR", "document this decision", "update the spec", "ADR for X". Run BEFORE coding when the decision is upfront, or AFTER landing when the right call only became clear during implementation. Do not create ADRs for simple features, local implementation choices, routine dependency changes, or bug fixes that do not establish a durable rule.
