What it actually did when run

observed

Loaded in a sandbox with no network, a read-only filesystem and a recording stand-in for pi's API. This is what it called — not what the source suggests it might.

Tools registered checkpointrestore_conversation

Events subscribed tool_call

APIs called navigateTree.bindregisterCommandregisterToolsessionManager.getEntriesui.notifywaitForIdlewaitForIdle.bind

3 calls the source scan did not predict

navigateTree.bind · waitForIdle · waitForIdle.bind

Reached through a value the scan could not follow — passed as an argument, stored on another object, or returned by a helper.

Run against version 0.1.3 on 2026-08-02. Registration-time behaviour under default settings; other configurations may differ.
