 ### Protected Tools
 
 By default, these tools are always protected from pruning:
-`task`, `skill`, `todowrite`, `todoread`, `compress`, `batch`, `plan_enter`, `plan_exit`
+`task`, `skill`, `todowrite`, `todoread`, `compress`, `batch`, `plan_enter`, `plan_exit`, `write`, `edit`
 
 The `protectedTools` arrays in `commands` and `strategies` add to this default list.
 
-For the `compress` tool, `compress.protectedTools` ensures specific tool outputs are appended to the compressed summary. It defaults to an empty array `[]` but always inherently protects `task`, `skill`, `todowrite`, and `todoread`.
+For the `compress` tool, `compress.protectedTools` ensures specific tool outputs are appended to the compressed summary. By default it includes `task`, `skill`, `todowrite`, and `todoread`.
