PR Description: [log] Add namespace loggers to three workflow files

PR Number: #33453
Repository: github/gh-aw
Type: observability
Breaking: false

Summary

Added structured logging instrumentation to three workflow package files (command_dispatch_validation.go, error_recovery.go, gh_aw_setup_steps.go) to improve observability of workflow compilation and validation processes. All changes are purely additive—no logic, APIs, or behavior modified.

Changes by File

pkg/workflow/command_dispatch_validation.go

• Change Type: modified
• Impact: medium
• Description: Added namespace logger workflow:command_dispatch_validation and logging statements to trace workflow_dispatch input validation decisions
• Key Additions:
  • Module-scoped logger: commandDispatchValidationLog = logger.New("workflow:command_dispatch_validation")
  • Log statement tracking validation triggers (slash_command, label_command presence)
  • Log statements for required input detection and validation outcomes

pkg/workflow/error_recovery.go

• Change Type: modified
• Impact: medium
• Description: Added namespace logger workflow:error_recovery and logging throughout the error recovery pipeline
• Key Additions:
  • Module-scoped logger: errorRecoveryLog = logger.New("workflow:error_recovery")
  • Logging for error message expansion, prioritization, truncation decisions
  • Logging for critical syntax error detection patterns

pkg/workflow/gh_aw_setup_steps.go

• Change Type: modified
• Impact: medium
• Description: Added namespace logger workflow:gh_aw_setup_steps and logging for setup step generation logic
• Key Additions:
  • Module-scoped logger: ghAwSetupLog = logger.New("workflow:gh_aw_setup_steps")
  • Logging for action mode selection (dev vs. production)
  • Logging for action reference resolution, pinning logic, and fallback paths
  • Parameter tracking (action_mode, action_repo, cli_version, with_field_count)

Impact Assessment

• Functionality: No functional changes—all additions are observability instrumentation
• Performance: Negligible—logging calls are conditional and structured
• Debugging: Significantly improved—enables tracing of validation, error recovery, and setup step generation decisions
• Maintenance: Positive—structured namespaces (workflow:*) enable targeted log filtering

Testing Considerations

• Existing tests remain valid (no behavior changes)
• Log output can be verified manually or through integration tests
• No new test coverage required for observability-only changes

Dependencies

• Uses existing github.com/github/gh-aw/pkg/logger package
• No new dependencies introduced

Rollout Risk

Low — Changes are additive and non-breaking. Logging infrastructure already exists in codebase.
