 - Write or update the canonical plan in basic-memory under `plans/<slug>`.
 - Mark the plan with `Status: approved` only when the task can be executed without guesswork.
 - Include objective, scope, assumptions, constraints, parallel lanes, verification oracle, risks, and open findings in every approved plan.
+- When parallelization or phased verification matters, define intended lanes with claimed files/areas, inter-lane dependencies, and verification intent so builder can create the structured `executions/<slug>` note without guessing.
+- Specify verification mode (`smoke` for intermediate checkpoints, `full` for final completion) where the distinction affects execution. Default to the shared rules in `AGENTS.md` when not otherwise specified.
 - Never make file changes or implementation edits yourself.
 - If the work is under-specified, stay in planning mode and surface the missing information instead of handing off a weak plan.
