What's Wrong?

I have a PostToolUse hook for ExitPlanMode tool

this hook works fine when i accept the plan without clearing context
but when you accept the plan and clear context, then the hook is not triggered

What Should Happen?

accepting a plan with the clear context action should still trigger the hook

Error Messages/Logs

no error message

Steps to Reproduce

create an exit plan mode hook:

e.g.

{
  "hooks": {
    "PostToolUse": [
      {
        "matcher": "ExitPlanMode",
        "hooks": [
          {
            "type": "command",
            "command": "echo \"=== $(date) ===\" >> \"$CLAUDE_PROJECT_DIR/exitplanmode-hook.log\"; jq '.' >> \"$CLAUDE_PROJECT_DIR/exitplanmode-hook.log\" 2>&1 || cat >> \"$CLAUDE_PROJECT_DIR/exitplanmode-hook.log\""
          }
        ]
      }
    ]
  }
}

start claude code, generate a plan, accept it with the clear context option, see that no exitplanmode-hook.log file is created

start claude code, generate a plan, accept it without clearing context, see that the exitplanmode-hook.log file is correctly created
