From 8714109614ce636ef99e4fc748a1db872d8e3c5c Mon Sep 17 00:00:00 2001 From: Ashwin Bhat Date: Mon, 2 Feb 2026 10:08:08 -0800 Subject: [PATCH 1/7] feat: add missing hook event types and update existing hook inputs Add support for previously missing hook event types: - Notification, SessionStart, SessionEnd, SubagentStart, PermissionRequest, and Setup hook events and their inputs - Corresponding hook-specific output types for each new event Update existing hook types with new fields: - Add tool_use_id to PreToolUse and PostToolUse hook inputs - Add additionalContext to PreToolUseHookSpecificOutput - Add updatedMCPToolOutput to PostToolUseHookSpecificOutput - Add agent_id, agent_transcript_path, agent_type to SubagentStopHookInput Remove outdated comment about SDK not supporting certain hook events.
