Overview

The parse*Config implementations for safe-output creation actions repeat the same parse pipeline across three files with mostly field-level differences. This creates a maintenance hotspot where validation and parsing behavior can drift.

The duplicated sequence appears in:

• create-issue
• create-discussion
• create-pull-request

Critical Information

• Severity: Medium
• Occurrences: 3
• Duplication size: ~20-30 lines repeated per implementation (core parsing flow)
• Risk: Inconsistent behavior when updating preprocessing/unmarshal/default logic

Duplication Details

Pattern: repeated parse pipeline in parse*Config methods:

1. Check key exists in outputMap
2. Extract configData
3. preprocessExpiresField(...)
4. preprocessBoolFieldAsString(...) loop
5. preprocessIntFieldAsString(..., "max", ...)
6. unmarshalConfig(...) with identical fallback handling
7. Default max handling

Locations:

• pkg/workflow/create_issue.go:29
• pkg/workflow/create_discussion.go:31
• pkg/workflow/create_pull_request.go:42

// Unmarshal into typed config struct
var config CreateIssuesConfig
if err := unmarshalConfig(outputMap, "create-issue", &config, createIssueLog); err != nil {
	createIssueLog.Printf("Failed to unmarshal config: %v", err)
	// For backward compatibility, handle nil/empty config
	config = CreateIssuesConfig{}
}

// Set default max if not specified
if config.Max == nil {
	config.Max = defaultIntStr(1)
}

Impact Analysis

• Maintainability: Any parser behavior change must be applied in 3 places.
• Bug risk: Easy to introduce subtle divergence in bool/int preprocessing or defaulting semantics.
• Code bloat: Repeated orchestration code obscures entity-specific rules.

Refactoring Recommendations

1. Extract shared parse orchestration helper

• Suggested location: pkg/workflow/safe_outputs_parser_shared.go
• Candidate API: generic/helper that accepts key name, logger, bool fields, and a post-process callback for entity-specific defaults.
• Estimated effort: Medium (3-5 hours)

2. Keep entity-specific behavior in focused hooks

• Example hooks:
  • assignee normalization (create-issue)
  • category normalization/fallback (create-discussion)
  • reviewers/protected-files logic (create-pull-request)
• Benefit: shared validation path + explicit per-entity extension points

Implementation Checklist

• Define common parse pipeline helper
• Migrate parseIssuesConfig
• Migrate parseDiscussionsConfig
• Migrate parsePullRequestsConfig
• Add regression tests for shared preprocessing/default behavior
• Verify no behavior drift in existing safe-output tests
