Robust Error Handling

[behrangsa]

Summary

Implement comprehensive error handling for all failure scenarios with clear, actionable error messages.

Acceptance Criteria

• Handle Git command not found scenarios
• Detect and report non-Git directories
• Handle permission errors gracefully
• Validate directory paths (prevent .. traversal)
• Provide clear error messages for each failure type
• Return appropriate exit codes
• Log errors appropriately without exposing sensitive information

Priority: High

Effort: 5 story points
Phase: Construction

Source

Reverse engineered from error conditions in husky/index.js and test cases

Dependencies

• Depends on: Hook Execution Runtime #3 (Hook Execution Runtime)
• Relates to: Comprehensive Test Infrastructure #5 (Test Infrastructure), Cross-Platform Compatibility #7 (Cross-Platform Compatibility)

Error handling needs a working hook runtime to handle errors from. It should be tested thoroughly.
