MED-001: Enhanced Typing Indicator Implementation

Overview

Enhanced Discord typing indicator to provide continuous visual feedback during long-running Claude operations (30s-5min).

Problem

Discord automatically cancels typing indicators after 10 seconds, but Claude operations can take much longer. Users had no feedback that the bot was still working on their request.

Solution

Implemented persistent typing loop that re-triggers every 8 seconds (before Discord's 10s timeout) until Claude responds.

Implementation

New Method: _maintain_typing

Continuously loops typing indicator until stop event is set:

  • Enters typing state via async context manager
  • Waits for stop_event with 8-second timeout
  • On timeout, loops to re-enter typing
  • On stop event, exits immediately
  • Handles exceptions gracefully without crashing

Updated _handle_claude_request

  • Creates asyncio.Event() to control typing lifecycle
  • Starts _maintain_typing as background task
  • Stops typing in finally block (ensures cleanup on success, error, or timeout)

Testing

Added 8 comprehensive tests:

  1. test_typing_starts_on_request_begin - Verifies typing starts immediately
  2. test_typing_loops_for_long_operations - Verifies 20s operation triggers 2+ typing cycles
  3. test_typing_stops_on_successful_completion - No hang on success
  4. test_typing_stops_on_error - Typing cleaned up on Claude error
  5. test_typing_stops_on_timeout - Typing cleaned up on asyncio.TimeoutError
  6. test_typing_stops_on_exception - Typing cleaned up on unexpected exception
  7. test_maintain_typing_loops_until_stopped - Direct method test (12s = 2+ cycles)
  8. test_maintain_typing_stops_immediately_on_event - Event stop < 2s (not full 8s wait)

All tests passing (27/27)

UX Improvements

  • Users now see continuous typing indicator for operations >10s
  • Clear visual feedback that bot is working
  • No false "bot stopped responding" confusion
  • Typing automatically stops when response arrives

Edge Cases Handled

  • Claude timeout → typing stops, error shown
  • Claude error → typing stops, error shown
  • Bot restart mid-request → typing naturally stops
  • Multiple messages queued → HIGH-004 locks handle sequencing

Files Changed

  • /opt/projects/claude-coordinator/claude_coordinator/bot.py

    • Added _maintain_typing method (22 lines)
    • Enhanced _handle_claude_request with typing task management

  • /opt/projects/claude-coordinator/tests/test_bot.py

    • Added 8 new test cases
    • Removed old single typing test (superseded by new comprehensive tests)

Deployment

No breaking changes. Existing functionality preserved. Safe to deploy immediately.

# Tests pass
pytest tests/test_bot.py -v  # 27 passed

# Restart bot to apply changes
pkill -f "python -m claude_coordinator.bot"
python -m claude_coordinator.bot &

Future Enhancements (Optional - Not Implemented)

Could add status messages for very long operations (>30s):

  • "⏳ Still processing..." after 30s
  • "⏳ Still processing (1m elapsed)..." every 30s
  • Delete status message when response arrives

This was considered but not implemented to keep the enhancement focused on the core typing indicator improvement.
