[Code Quality] Improve Documentation Coverage to Meet 5-10% Threshold

[github-actions]

Description

The Daily Code Metrics Report identified that documentation coverage is below the recommended threshold. Current code-to-docs ratio is 26.1:1 (3.8% coverage), while the recommended range is 5-10% (10-20:1 ratio).

Current State

• Documentation Files: 115 files in docs/
• Documentation LOC: 18,147 lines
• Code-to-Docs Ratio: 26.1:1
• Coverage: 3.8% of codebase
• Quality Score Impact: Scores only 7.0/20 points (34.8%) for documentation

Suggested Changes

Priority 1: Core Package Documentation

• Add comprehensive README files to key packages:
  • pkg/workflow/ - Workflow compilation architecture
  • pkg/parser/ - Frontmatter parsing and validation
  • pkg/cli/ - Command structure and patterns
  • pkg/console/ - Output formatting system

Priority 2: Complex Workflow Documentation

• Document frequently-changed workflows with high complexity:
  • Security alert burndown workflow (4,539 LOC changed last week)
  • Dependabot burner workflow (2,013 LOC added)
  • Add architectural diagrams for multi-step workflows

Priority 3: API and Function Documentation

• Expand inline godoc comments for exported functions
• Add examples to complex function documentation
• Document error handling patterns and return values

Priority 4: Architecture Guides

• Create high-level architecture documentation:
  • Workflow compilation pipeline
  • Safe outputs system architecture
  • MCP server integration patterns
  • Sandbox and security model

Success Criteria

• Code-to-docs ratio improved to 15:1 or better (target: 6-7% coverage)
• All major packages have README.md files with examples
• Complex workflows have architectural documentation
• Quality score documentation component improves to 10+/20 points (50%+)
• make lint passes (godoc comments for exported symbols)

Files Affected

Documentation to add:

• pkg/workflow/README.md (new)
• pkg/parser/README.md (new)
• pkg/cli/README.md (new)
• pkg/console/README.md (new)
• docs/src/content/docs/architecture/ (new directory)

Existing files to enhance:

• Expand inline comments in pkg/workflow/compiler.go
• Add examples to pkg/parser/frontmatter.go
• Document error patterns in pkg/cli/*_command.go

Priority

High - Documentation gaps impact developer onboarding, maintainability, and quality scores

Estimated Effort

Medium-Large (8-12 hours)

• README creation: 4-6 hours
• Inline documentation: 2-3 hours
• Architecture guides: 2-3 hours

Extracted from Daily Code Metrics Report discussion #13455

Key Insight from Report:

"Current code-to-docs ratio of 26.1:1 is high. Target 10-15:1 by expanding inline documentation and architectural guides. Consider documenting complex workflows and pkg modules more thoroughly."

Implementation Notes

Follow existing documentation patterns:

• Use godoc format for Go code comments
• Follow Diátaxis framework for docs/ structure (see (a)documentation skill(/a))
• Include code examples in all READMEs
• Link to related documentation and workflows

Context

This addresses one of the top recommendations from the daily code quality audit. Improving documentation coverage will:

1. Reduce onboarding time for new contributors
2. Improve maintainability of complex systems
3. Increase overall quality score (currently 67.6/100)
4. Meet industry standard documentation thresholds
