         For pure analysis or informational tasks, requires_external_effect should be false.
         For tasks that modify files, run processes, or produce verifiable side effects, requires_external_effect should be true.
         Read-only operations (file_read, file_search, and dir list) do not create an external effect and must use requires_external_effect=false.
-        When requires_external_effect is false, required_effect_tools must be empty. When true, it must contain at least one Tool and only the Tool(s) that prove this task's own expected effect.
+        A read/search/list task must name file_read, file_search, or dir in required_tools even though requires_external_effect is false. A pure response task uses an empty array. When requires_external_effect is true, required_tools must include the effect Tool that proves this task's own expected effect.
         Preserve every user-supplied absolute path, executable, cwd, argument array, operation name, and literal value exactly in the task that uses it; never abbreviate these values into a shell-like command.
         Keep each task limited to its own described operation. Do not put later dependent operations into an earlier task.
         A single task is valid for simple requests.
