+### Dependencies: Avoid the Temporal Trap
+
+When adding dependencies, think "X **needs** Y" not "X **comes before** Y":
+
+```bash
+# ❌ WRONG: "Phase 1 blocks Phase 2" → bd dep add phase1 phase2
+# ✅ RIGHT: "Phase 2 needs Phase 1" → bd dep add phase2 phase1
+```
+
+Verify with `bd blocked` - tasks should be blocked by prerequisites, not dependents.
