New Features

• Enhanced ReAct Agent Logic:
  • Implemented improved iterative reasoning and action mechanisms.
  • The agent now recovers more gracefully from models producing invalid JSON in response.
  • Enhanced in-band recovery and error messaging for better user interaction.
  • Code reference: agent/react/react_agent.go

Improvements

• Code Refactoring:

  • The codebase has been reorganized for greater modularity, splitting different logical parts into dedicated packages (such as core, planexec, react, and tools).
  • Clear separation of concerns, improving both readability and maintainability.
  • Code reference: Multiple files under agent/, tools/, and core/ directories.

• Policy Enforcement Updates:

  • Improved safety checks within the agent policy model.
  • Enhanced context-specific guidance to prevent undesired actions.
  • Code reference: agent/core/policy.go

  • More robust handling of LLM token budgets, making iterative tasks more predictable.
  • Code reference: agent/core/budget.go

Bug Fixes

• Tool Integration:

  • Fixed issues where file operations might not respect path constraints properly.
  • Addressed shell tool command handling errors, particularly with variadic arguments.
  • Code reference: Various files within tools/

• Template Processing:

  • Resolved issues with Go template rendering within agent steps, reducing the occurrence of template syntax errors.
  • Code reference: agent/planexec/template_step.go

• Compatibility and Resilience:

  • Corrected JSON parsing logic to handle output wrapped in markdown code fences correctly.
  • Enhanced compatibility with different JSON action types generated by the model.
  • Code reference: agent/react/react_agent.go

Other Changes

• Testing Enhancements:
  • Expanded unit test coverage to validate new behaviors and ensure system robustness against unexpected input.
  • Increased resilience against external dependencies changes.
  • Code reference: Various test files under agent/planexec/ and agent/react/
