Struct Agent 

pub struct Agent { /* private fields */ }

MAX_ITERATIONS Documentation:

Why 200 iterations?

• Sufficient for most common tasks (file edits, code review, simple builds)
• Prevents infinite loops and runaway operations
• Balances task completion with resource efficiency

What happens when limit is reached?

• Agent stops execution gracefully
• User receives detailed warning message explaining:
  • Task status (may not be complete)
  • Reason for stopping (iteration limit)
  • Next steps (continue, break down task, or resume)

Future improvements:

• Dynamic adjustment based on task complexity
• User-configurable limits in config file
• Auto-resume with state preservation
• Progress indicators showing iteration count

Examples:

• Simple task (edit file): ~5-10 iterations
• Medium task (refactor module): ~15-30 iterations
• Complex task (build system): ~40-50 iterations (may hit limit) Full Agent with event output
