Agent Manager v2.0: Implement Specific Error Codes for Programmatic Handling

[rysweet]

Overview

Enhance the Agent Manager with specific error codes to improve programmatic handling and debugging capabilities. This addresses feedback from PR #39 code review.

Current State

The Agent Manager currently uses basic return codes (0 for success, 1 for general failure). While functional, this limits programmatic error handling and debugging capabilities.

Proposed Enhancement

Implement a structured error code system that provides specific information about failure types:

Error Code Categories

• 10x: Authentication Errors

  • 101: Invalid GitHub token
  • 102: SSH key authentication failed
  • 103: Repository access denied
  • 104: Token expired or revoked

• 20x: Network/Repository Errors

  • 201: Repository not found
  • 202: Network connection failed
  • 203: Repository clone/fetch failed
  • 204: Repository format invalid

• 30x: Agent Validation Errors

  • 301: Agent manifest missing or invalid
  • 302: Agent dependencies unresolved
  • 303: Agent version conflict
  • 304: Agent format validation failed

• 40x: Installation Errors

  • 401: Insufficient disk space
  • 402: File permissions error
  • 403: Installation rollback failed
  • 404: Configuration validation failed

• 50x: Cache/Storage Errors

  • 501: Cache corruption detected
  • 502: Cache directory inaccessible
  • 503: Cache size limit exceeded
  • 504: Cache invalidation failed

Implementation Approach

1. Error Code Constants: Define error codes as constants with descriptive names
2. Error Context: Include additional context (error message, suggested resolution)
3. Logging Integration: Enhanced logging with error codes for debugging
4. Documentation: Comprehensive error code reference for users
5. Backward Compatibility: Maintain existing return code behavior while adding new error system

Benefits

• Better Automation: Scripts can handle specific error types appropriately
• Improved Debugging: Clear identification of failure causes
• Enhanced Monitoring: Structured error tracking and alerting
• User Experience: Specific error messages with suggested resolutions

Acceptance Criteria

• Error code system defined and documented
• All Agent Manager functions return specific error codes
• Error codes include human-readable descriptions
• Logging enhanced with error code information
• Documentation updated with error code reference
• Tests updated to verify error code behavior
• Backward compatibility preserved

Priority

High - This enhancement significantly improves the Agent Manager's enterprise readiness and programmatic integration capabilities.
