Ben Brandt	17aad5b7a1	Provide `agentInfo` on initialization response (#123 ) - Provide agentInfo on initialization - Prep 0.6.10	2025-10-24 17:02:07 +00:00
Steffen Deusch	dadc7f9f40	prevent invalid locations when read call has no path (#121 ) The ACP spec has the path as a required field for tool call locations, but I've seen Claude generate read calls without an input path, which would generate: ```json { "content": [], "kind": "read", "locations": [ { "line": 0 } ], "rawInput": {}, "sessionUpdate": "tool_call", "status": "pending", "title": "Read File", "toolCallId": "toolu_012PzeR5whUjWN4ij2HBubJw" } ``` And then fail to parse as SessionNotification in the SDK.	2025-10-24 12:49:43 +00:00

Ben Brandt	0d97bb4753	Fix type holes in switch statements (#119 ) We were relying on unreachable to catch stuff for us, but it wasn't erroring because we were manually casting a few of the types to never, leading to a bug when a hook response was encountered. We'll revisit showing these hook responses to the user once ACP supports multiple types of status messages.	2025-10-24 10:19:41 +00:00
