Copilot CLI hooks are not working at all after resuming a session

[DonJayamanne]

I am using this hooks.json:

{
	"version": 1,
	"hooks": {
		"sessionStart": [
			{
				"type": "command",
				"bash": "touch /tmp/.worktree-sessionStart"
			}
		],
		"sessionEnd": [
			{
				"type": "command",
				"bash": "touch /tmp/.worktree-sessionEnd"
			}
		],
		"agentStop": [
			{
				"type": "command",
				"bash": "touch /tmp/.worktree-agentStop"
			}
		],
		"userPromptSubmitted": [
			{
				"type": "command",
				"bash": "touch /tmp/.worktree-userPromptSubmitted"
			}
		],
		"preToolUse": [
			{
				"type": "command",
				"bash": ""
			}
		],
		"postToolUse": [
			{
				"type": "command",
				"bash": ""
			}
		]
	}
}

I see 3 files created on session start. Then I delete the 3 files and continue in the session. None of the files is created. I would have expected:

• userPromptSubmitted
• agentStop
