+### Turn Protection
+
+When enabled, turn protection prevents tool outputs from being pruned for a configurable number of message turns. This gives the AI time to reference recent tool outputs before they become prunable. Applies to both `discard` and `extract` tools, as well as automatic strategies.
+
 ### Protected Tools
 
 By default, these tools are always protected from pruning across all strategies:
 `task`, `todowrite`, `todoread`, `discard`, `extract`, `batch`
 
-The `protectedTools` arrays in each strategy add to this default list.
+The `protectedTools` arrays in each section add to this default list:
+- `tools.settings.protectedTools` — Protects tools from the `discard` and `extract` tools
+- `strategies.deduplication.protectedTools` — Protects tools from deduplication
+- `strategies.onIdle.protectedTools` — Protects tools from on-idle analysis
