Original Conversation found here

They tried the Mission mode in Droid. The PreToolUse and PostToolUse hooks fail when tasks are delegated to Worker (subagent) inside the session, failed to capture pre-task state and to parse hook event

PreToolUse: failed to capture pre-task state: tool_use_id is required
PostToolUse: failed to parse hook event: failed to parse hook input: json: cannot unmarshal string into Go struct field postToolHookInputRaw.tool_response of type struct { AgentID string "json:\"agentId\"" }

Steps to reproduce

1. Use Droid 0.99.0 in Mission mode
2. Delegate a task to a Worker (subagent)
3. Observe hook failures

Environment

• Droid 0.99.0
• Entire CLI 0.5.4 (746a74c)
• Go version: go1.26.2
• Fedora 43 via Homebrew
• Entire hook installed Mar 24
