[Schema Consistency] Schema Consistency Analysis - October 23, 2025

[github-actions[bot]]

🔍 Schema Consistency Check - 2025-10-23

Executive Summary

Completed comprehensive analysis of schema consistency across 4 key areas:

• ✅ Schema definitions (pkg/parser/schemas/)
• ✅ Parser/Compiler implementation (pkg/parser/, pkg/workflow/)
• ✅ Documentation (docs/src/content/docs/reference/)
• ✅ Real workflows (.github/workflows/)

Results: 12 inconsistencies found, ranging from critical validation gaps to documentation omissions.

Overall Assessment: B+ (85/100) - System is remarkably consistent with only minor gaps to address.

🚨 Critical Issues (Immediate Action Required)

1. Missing Enum Validation for reaction Field

Severity: Medium-High | Impact: Invalid reaction values could pass through without validation

Issue: Schema defines strict enum (+1, -1, laugh, confused, heart, hooray, rocket, eyes) but parser doesn't validate against it.

Location: pkg/workflow/compiler.go:1479

// Current code - NO VALIDATION
if reactionStr, ok := reactionValue.(string); ok {
    workflowData.AIReaction = reactionStr  // ❌ Accepts any string
}

Recommendation: Add validation:

validReactions := map[string]bool{
    "+1": true, "-1": true, "laugh": true, "confused": true,
    "heart": true, "hooray": true, "rocket": true, "eyes": true,
}
if reactionStr, ok := reactionValue.(string); ok {
    if !validReactions[reactionStr] {
        return fmt.Errorf("invalid reaction: %s (must be one of: +1, -1, laugh, confused, heart, hooray, rocket, eyes)", reactionStr)
    }
    workflowData.AIReaction = reactionStr
}

2. githubActionsStep Field - Zombie Field in Schema

Severity: High | Impact: Confusing for users, bloated schema

Findings:

• ✅ Defined in schema with full structure
• ❌ NOT parsed in pkg/parser/frontmatter.go
• ❌ NOT used in pkg/workflow/compiler.go
• ❌ NOT documented anywhere
• ❌ 0 usages in workflow files

Recommendation: Remove from schema entirely OR implement if it was planned functionality.

---

📝 Documentation Gaps

3. Major Fields Missing from Documentation

10 schema fields are implemented and used but missing from frontmatter.md:

Field	Schema	Parser	Workflows	Documentation
tools	✅	✅	46 uses	⚠️ Only in tools.md
imports	✅	✅	26 uses	❌ None
mcp-servers	✅	✅	0 uses	❌ None
name	✅	✅	0 uses	❌ None
jobs	✅	✅	0 uses	❌ None
post-steps	✅	✅	1 use	❌ None
runtimes	✅	✅	0 uses	❌ None
features	✅	✅	0 uses	❌ None
command	✅	✅	0 uses	⚠️ Only in triggers.md
githubActionsStep	✅	❌	0 uses	❌ None

4. imports Field - Heavily Used, Completely Undocumented

Severity: Medium | Impact: Users lack guidance for important feature

Evidence: Real usage found in audit-workflows.md:

imports:
  - shared/mcp/gh-aw.md
  - shared/jqschema.md
  - shared/reporting.md

Recommendation: Add documentation covering:

• Purpose: Include shared frontmatter configurations
• Format: Array of relative file paths
• Merge behavior with main frontmatter
• Execution order
• Example patterns

---

✅ What's Working Well

Permission Scopes - Perfect Consistency

All 15 GitHub permission scopes from schema are correctly validated:

• actions, attestations, checks, contents, deployments
• discussions, id-token, issues, models, packages
• pages, pull-requests, repository-projects, security-events, statuses

Location: pkg/workflow/permissions.go:347-375

Roles Enum - Fully Validated

Schema enum matches parser implementation:

• Schema: admin, maintainer, maintain, write, triage, all
• Parser: Defaults to ["admin", "maintainer", "write"]
• Validation: All values handled correctly in pkg/workflow/role_checks.go:79

Workflow Files - No Violations

Sampled 46 workflow files - all conform to schema with no violations found.

---

🔧 Schema Improvements Needed

7. Default Values Not Specified in Schema

Severity: Low | Impact: Ambiguity about field behavior

Examples:

• reaction: Code defaults to "eyes" but schema doesn't specify
• roles: Code defaults to ["admin", "maintainer", "write"] - not in schema
• permissions: Implicit behavior not documented

Recommendation: Add default properties to schema:

{
  "reaction": {
    "type": "string",
    "enum": ["+1", "-1", "laugh", "confused", "heart", "hooray", "rocket", "eyes"],
    "default": "eyes"
  }
}

📊 Detailed Analysis

Schema vs Parser Field Coverage

Analyzed all 31 top-level schema fields:

Status	Count	Examples
✅ Fully validated	20	on, permissions, roles, engine, network
⚠️ Extracted but not validated	7	reaction, tools, imports, mcp-servers
❌ Defined but unused	1	githubActionsStep
⚠️ Validation incomplete	3	tools (nested), safe-outputs, jobs

Nested Object Validation

Complex fields with nested structures:

1. tools (11 subproperties):

   • Schema: Fully defined
   • Parser: Extracts map
   • Status: ⚠️ Limited nested property validation

2. safe-outputs:

   • Schema: Complex structure
   • Parser: Dedicated validation in safe_outputs.go
   • Status: ✅ Well-implemented

3. engine:

   • Schema: Uses oneOf for string|object
   • Parser: Handles both formats
   • Status: ✅ Well-implemented

🎯 Recommendations by Priority

Immediate Actions (High Priority)

1. ✅ Add reaction enum validation in compiler.go
2. ✅ Remove or implement githubActionsStep field
3. ✅ Document imports field with examples
4. ✅ Document mcp-servers field

Short-term Actions (Medium Priority)

5. Add default values to schema JSON
6. Document post-steps, jobs, runtimes, features
7. Add validation for additional enum fields
8. Cross-reference tools.md from main frontmatter docs

Long-term Actions (Low Priority)

9. Consider JSON Schema $ref for reusable components
10. Add automated consistency tests (schema → parser → docs)
11. Generate documentation from schema programmatically
12. Add schema version field for evolution tracking

✅ Next Steps Checklist

For Schema Maintainers

• Add enum validation for reaction field in compiler
• Decide fate of githubActionsStep (remove or implement)
• Add default values to schema JSON
• Review other fields for unused definitions

For Documentation Team

• Document imports field with examples
• Document mcp-servers field
• Add post-steps, jobs, runtimes, features to frontmatter docs
• Cross-reference tools.md from main docs

• Add test for invalid reaction values (should fail gracefully)
• Add enum validation tests for all enum fields
• Add integration tests: schema → parser → workflow validation
• Consider automated consistency checks in CI/CD

/q add default eyes in schema and add reaction schema value validation in parser

[github-actions[bot]]

Agentic Q triggered by this discussion comment.

[github-actions[bot]]

✅ Q Workflow Optimization Complete

I've successfully implemented the requested changes to add default "eyes" reaction in the schema and reaction value validation in the parser.

Changes Implemented

1. Schema Enhancement

• Added "default": "eyes" to the reaction field in main_workflow_schema.json
• This documents the default behavior that was already implemented in the compiler

2. Parser Validation

• Created isValidReaction() helper function to validate reaction values
• Added validation in parseOnSection() to check reaction values during parsing
• Provides clear, helpful error messages when invalid reactions are used

3. Test Coverage

• Added TestInvalidReactionValue to verify validation works correctly
• Test ensures invalid values are rejected with helpful error messages

Example

Before: Invalid reaction values would be silently ignored or cause runtime issues

After: Clear compile-time error with helpful message:

Error: invalid reaction value 'invalid_emoji': must be one of [+1 -1 laugh confused heart hooray rocket eyes]

Pull Request

A pull request has been created with these changes. All modifications are minimal, surgical, and fully backward compatible with existing workflows.

The changes ensure:

• ✅ Early error detection during compilation
• ✅ Better developer experience with clear error messages
• ✅ Schema documentation for the default value
• ✅ Type safety and consistency across the codebase
