Story 1.4: Agentic Iteration Loop & Limits

[sevos]

Summary

• Implement agentic execution loop for multi-step reasoning before final result
• Add max_iterations safety constraint to prevent infinite loops
• Enable agents to think through problems iteratively with conversation continuity
• Maintain backward compatibility for simple single-step use cases

Tasks

• Implement agentic reasoning loop in Agent#execute method
• Enhance execution tracking for multi-step reasoning
• Add iteration loop control logic
• Add comprehensive testing for agentic loop

Development Decisions

• Reasoning Pattern: Continuous thought process (natural flow)
• Task Completion: Explicit "TASK_COMPLETE:" markers with Ruby parsing
• Iteration Tracking: Count all LLM calls regardless of content quality
• Max Iterations Safety: Meta-instruction injection for final iteration warnings

Test Plan

• Test multi-step reasoning functionality
• Test conversation continuity across iterations
• Test early termination scenarios
• Test max_iterations constraint behavior
• Test iteration tracking
• Test backward compatibility with single-step execution
