claude-code - 💡(How to fix) Fix docs: clarify whether UserPromptSubmit hook fires for MCP channel messages [1 participants]

TL;DR

The UserPromptSubmit hook's behavior for non-interactive input sources like MCP channel messages and tmux send-keys needs clarification to determine the best approach for implementing identity reinforcement.

Guidance

• Review the hooks documentation and related code to see if there are any implicit hints about the hook's behavior for different input sources.
• Test the UserPromptSubmit hook with MCP channel messages (e.g., Telegram plugin) and tmux send-keys injected input to observe its current behavior.
• Consider opening a documentation issue or pull request to add clarity on the hook's behavior for different input sources.
• If the hook does not fire for MCP channel messages, explore alternative hooks or implementation approaches that can achieve the desired identity reinforcement functionality.

Notes

The current documentation ambiguity makes it challenging to provide a definitive solution, and testing or clarification from the maintainers may be necessary to determine the best course of action.

Recommendation

Apply workaround: Test the UserPromptSubmit hook with different input sources to determine its current behavior and plan accordingly, as the documentation clarification may take time.
