+# Task 9: Fold vague plans into sub-goals
+
+**Plan**: high-leverage-contributions, teach-and-document
+**Status**: DONE
+**Deliverable**: Updated `CLAUDE.md` and `plans/`
+
+## What to do
+
+1. The plans `high-leverage-contributions.md` and `teach-and-document.md`
+   are behavioral norms, not executable plans. Their content is already
+   largely covered by sub-goals 7 (multiply impact through reach) and
+   8 (teach rather than just do).
+
+2. Review both plans for any concrete guidance not already in the
+   sub-goals. Merge anything useful into the relevant sub-goal text
+   in `CLAUDE.md`.
+
+3. Remove the two plan files.
+
+4. Update `plans/README.md` to reflect the reduced plan list.
+
+## Done when
+
+- No plan file exists that is just a restatement of a sub-goal.
+- Any actionable content from the removed plans is preserved in
+  `CLAUDE.md`.
