| 5 | +- **Task ID**: 004 |
| 6 | +- **Epic**: pipeline-fixes |
| 7 | +- **Name**: Standardize tool return format |
| 8 | +- **Status**: TODO |
| 9 | +- **Priority**: High |
| 10 | +- **Size**: L (12 hours) |
| 11 | +- **Created**: 2025-08-22T13:29:31Z |
| 12 | +- **Dependencies**: None |
| 13 | +- **Can Run in Parallel**: Yes |
| 14 | + |
| 15 | +## Description |
| 16 | + |
| 17 | +Standardize the return format for all tools to use a consistent structure with `result`, `success`, and `error` fields. Currently, tools return inconsistent formats, making it difficult for pipeline systems to handle outputs uniformly. |
| 18 | + |
| 19 | +The standardized format should be: |
| 20 | +```python |
| 21 | +{ |
| 22 | + "success": bool, # True if operation succeeded |
| 23 | + "result": Any, # The actual result data (if success=True) |
| 24 | + "error": str | None, # Error message (if success=False) |
| 25 | + "metadata": dict | None # Optional metadata about the operation |
| 26 | +} |
| 27 | +``` |
| 28 | + |
| 29 | +## Acceptance Criteria |
| 30 | + |
| 31 | +- [ ] All tools return consistent format with success/result/error structure |
| 32 | +- [ ] Base Tool class defines and enforces standard return format |
| 33 | +- [ ] Pipeline systems can rely on consistent return structure |
| 34 | +- [ ] Error handling is standardized across all tools |
| 35 | +- [ ] Backward compatibility maintained where possible |
| 36 | +- [ ] Tool documentation reflects standard return format |
| 37 | + |
| 38 | +## Files Affected |
| 39 | + |
| 40 | +- Base Tool class definition |
| 41 | +- All tool implementations (likely 20+ files) |
| 42 | +- Pipeline control systems that process tool outputs |
| 43 | +- Test files for tools |
| 44 | +- Tool interface documentation |
| 45 | + |
| 46 | +## Implementation Notes |
| 47 | + |
| 48 | +- Update base Tool class to define standard return format |
| 49 | +- Create helper methods for consistent return value creation |
| 50 | +- Update all individual tool implementations |
| 51 | +- Consider using a decorator or wrapper for automatic format conversion |
| 52 | +- Handle edge cases where tools currently return complex formats |
| 53 | +- Ensure error information is preserved and meaningful |
| 54 | + |
| 55 | +## Testing Requirements |
| 56 | + |
| 57 | +- Test all tools return standard format |
| 58 | +- Verify pipeline systems work with new format |
| 59 | +- Test error cases return proper error structure |
| 60 | +- Integration tests with control systems |
| 61 | +- Backward compatibility tests where applicable |
| 62 | +- Performance testing to ensure format changes don't impact speed |
| 63 | + |
| 64 | +## Definition of Done |
| 65 | + |
| 66 | +- All tools return standardized format |
| 67 | +- Base Tool class enforces consistent returns |
| 68 | +- Pipeline systems updated to use standard format |
| 69 | +- All tests pass with new return format |
| 70 | +- Tool documentation updated |
| 71 | +- Error handling is consistent and informative across all tools |
