Fix missing last comment when sending to Claude

promptium-ai · claude · promptium-ai · commit 1cf0150164de · 2025-08-27T21:38:59.000Z
When sending code review comments to Claude via tmux, the last comment line was not getting a proper newline, causing it to be missing from the Claude input. The issue was in DiffView.ts where the code skipped sending 'Escape Enter' after the last message line. This fix ensures all lines get proper newlines, including the last one. Changes: - Fix DiffView.ts to send newlines after all message lines - Enhance FakeTmuxService with key tracking for testing - Add comprehensive e2e test to verify the fix 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
