[github-actions]

Summary

Enhanced 5 Go files in the pkg/workflow directory with debug logging statements to improve troubleshooting and development.

Files Modified

1. pkg/workflow/frontmatter_extraction_metadata.go

   • Added logger declaration: frontmatterMetadataLog
   • Added logging for tracker ID extraction and validation
   • Added logging for tools timeout extraction with type information

2. pkg/workflow/safe_outputs_config_messages.go

   • Added logger declaration: safeOutputMessagesLog
   • Added logging for messages configuration parsing
   • Added logging for mentions configuration with type detection
   • Added logging for message config serialization

3. pkg/workflow/safe_outputs_config_helpers_reflection.go

   • Added logger declaration: safeOutputReflectionLog
   • Added logging for reflection-based safe output detection
   • Added logging for enabled tool name collection
   • Added logging for custom job tool discovery

4. pkg/workflow/close_entity_helpers.go

   • Enhanced existing logging in parseCloseEntityConfig function
   • Added logging for default max value assignment
   • Added logging for target-repo slug validation failures

5. pkg/workflow/expression_patterns.go

   • Added logger declaration: expressionPatternsLog
   • Added init function with logging for regex pattern compilation

Logging Guidelines Followed

✅ Logger naming convention: pkg:filename pattern (e.g., workflow:frontmatter_extraction_metadata)
✅ Logger arguments have no side effects
✅ Logging added at function entry for important operations
✅ Logging added for state changes and validation results
✅ Meaningful, helpful logging messages
✅ No duplicate logging with existing logs

Validation

• ✅ Build successful: make build
• ✅ Compilation test successful: go run ./cmd/gh-aw compile dev
• ✅ Debug logs appear correctly when DEBUG=* is set

Example Debug Output

workflow:frontmatter_extraction_metadata Extracting and validating tracker-id
workflow:safe_outputs_config_helpers_reflection Checking if any safe outputs are enabled using reflection
workflow:safe_outputs_config_helpers_reflection Found enabled safe output field: MissingTool
workflow:expression_patterns Initializing expression pattern regex compilation
