📈 Performance Impact

🎯 Feature Highlights

1. Progress Bar Debouncing

Before:

🚀 Running: pipeline (2 stages)
🚀 Running: pipeline (2 stages)  # Duplicate
🚀 Running: pipeline (2 stages)  # Duplicate
🚀 Running: pipeline (2 stages)  # Duplicate

After:

🚀 Running: pipeline (2 stages)
🚀 Running: pipeline (2 stages)  # Only 2 renders!

2. Enhanced Error Messages

Before:

Error: Agent execution failed

After:

⏱️ Agent Execution Timeout
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Error: Agent execution timeout after 60000ms

💡 Suggestions:
  1. Increase timeout in agent configuration
  2. Check if the AI service is responding slowly
  3. Simplify the input prompt
  4. Try running again - this may be temporary
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

ℹ️  Run with --debug for detailed stack trace

3. Interactive Template Generation

$ ./cotor template compare -i my-pipeline.yaml

🎨 Interactive Template Generation

Pipeline name: my-awesome-compare
Pipeline description: Compare AI coding solutions
Number of agents (1-5): 3
Agent 1 name (claude/gemini/codex): claude
Agent 2 name (claude/gemini/codex): gemini
Agent 3 name (claude/gemini/codex): codex
Execution mode (SEQUENTIAL/PARALLEL/DAG): PARALLEL
Timeout per agent (ms, default 60000): 90000

✨ Generating customized template...
✅ Template created: my-pipeline.yaml

4. Pipeline Resume

$ ./cotor resume

📋 Available Checkpoints
