What's Wrong?

Observed (hook log, same session, same agent call shape)

| Answered in | Agent's tool_use input keys (transcript) | Hook tool_input keys | Hook tool_response keys | Key order |
|---|---|---|---|---|
| Terminal | questions, metadata | questions, metadata, answers, annotations | questions, answers, annotations | as authored |
| Web | questions, metadata | answers, questions | questions, answers | alphabetical (header, multiSelect, options, question; description, label) |

The hook runs in both cases, but for the web answer the metadata the agent passed is missing from the hook's tool_input, annotations are missing, and the questions are re-serialized. The transcript's toolUseResult has the same difference. Records identify the client nowhere (entrypoint is cli for both).

Impact

Hooks that use AskUserQuestion's metadata to identify what a question was about (for example to record a decision) silently lose web answers. Requests: keep the original tool_input fields (at least metadata) when an answer arrives from Remote Control; optionally record the answering client.

What Should Happen?

In both cases the hook's tool_input contains the input the agent passed to the call (including metadata), as it does when the question is answered in the terminal, so a hook can tell which call was answered.

Error Messages/Logs

Steps to Reproduce

1. In an empty directory, add .claude/settings.json with a PostToolUse hook (matcher *) that logs the key names of the hook input's tool_input and tool_response.
2. Start claude there. Have the agent call AskUserQuestion with one question and metadata: { "source": "probe-1" }. Answer it in the terminal.
3. Connect the session to Remote Control. Have the agent make the same call with metadata: { "source": "probe-3" }. Answer it in the web interface.
