Implement event hooks for Agents WebView and Text-to-Speech for CoPilot chat

[paulpv]

Summary

Explore adding hooks into the Agents WebView DOM to capture events and using text-to-speech to vocalize messages generated by CoPilot in the chat interface.

Context

This feature is part of the exploration to enhance accessibility and interactive feedback in the CoPilot agent chat experience by providing audible readouts of messages.

Current State:

• 🔴 DOM event hooks in Agent WebView not yet explored
• 🔴 No text-to-speech for CoPilot chat messages

Dependencies:

• None identified at this stage

Acceptance Criteria

• DOM events for relevant CoPilot message updates are captured in the WebView
• Text-to-speech is triggered for each new message from CoPilot
• Feature can be easily enabled/disabled
• Documentation updated in IMPLEMENTATION_STATUS.md
• All sub-issues completed

Sub-Issues

• #XXX - Investigate WebView DOM access and JavaScript event capture
• #XXX - Integrate text-to-speech API for message playback
• #XXX - Add on/off toggle and settings

AI Implementation Prompt

Explore hooking event listeners into the Agents WebView DOM to capture and react to CoPilot chat text updates. Implement a text-to-speech pipeline so messages CoPilot sends in chat are audibly spoken. Consider cross-platform requirements for WebView (Electron/Chromium/WebKit) and accessibility concerns. Reference relevant OS/web APIs for TTS.

Reference: See IMPLEMENTATION_STATUS.md section [link]

Testing Plan

How to verify the feature works end-to-end:

Manual Verification:

1. Trigger a new message from CoPilot in the chat interface
2. Verify an event is hooked in the Agents WebView and triggers TTS
3. Listen to the spoken rendition of the text, ensure accuracy
