+- `[recurring]` **Asked the execution-mode question AGAIN** ("subagent-driven vs inline —
+  which approach?") at the end of `writing-plans`, despite the 2026-06-05 standing
+  preference *and* the `always-subagent-driven-execution` memory both saying don't ask.
+  Root cause: the `writing-plans` skill's "Execution Handoff" step scripts the menu, and
+  I followed the skill text over the user's standing override. Second occurrence →
+  escalate from "skip the prompt" to a **hard rule**: never present the execution-mode
+  menu; finishing a plan means defaulting straight to subagent-driven.
+- `[friction]` **Don't pause for approval between writing a plan and implementing it.**
+  The user has standing pre-approval to carry straight through plan → implementation. The
+  brainstorming/plan flow already has explicit approval gates (design approval, spec
+  review); adding another "shall I proceed to implement?" gate after the plan is written
+  is redundant friction. → After `writing-plans` finishes, begin subagent-driven
+  implementation directly. The only reason to stop is a genuine blocker or ambiguity, not
+  a routine checkpoint.
