Skill: Spec Validation

Overview

This skill validates specification quality:

• Completeness checks
• Consistency verification
• Ambiguity detection
• Requirement alignment
• Quality scoring

Purpose

Ensure specifications are complete and correct. Use this skill:

• Before implementation
• During design review
• For spec quality audits
• When requirements change

Execution Flow

1. LOAD requirement specifications
2. LOAD test specifications
3. VALIDATE structure and format
4. CHECK completeness
5. VERIFY consistency
6. DETECT ambiguities
7. SCORE quality
8. REPORT findings

Pass Summary

✅ All IDs are unique ✅ All IDs follow format standard ✅ All statuses are valid ✅ All priorities are valid ✅ All cross-references exist ✅ 18/20 requirements have test cases

Recommendations

1. Critical: Fix 3 errors to pass validation
2. Important: Address 8 warnings for quality
3. Optional: Review 5 info items for improvement

Auto-Fix Available

Run with --fix to automatically:

• Add missing ID prefixes
• Format inconsistent values
• Add empty sections with placeholders

## Example Usage

### Example 1: Validate Single Spec

USER: /spec-validation specs/auth-spec.md

SKILL OUTPUT:

Spec Validation: auth-spec.md

Summary

• Errors: 2
• Warnings: 5
• Score: 85/100

❌ FAILED - Fix 2 errors to pass validation

### Example 2: Strict Mode

USER: /spec-validation specs/auth-spec.md --strict

SKILL OUTPUT:

Spec Validation (Strict Mode)

Summary

• Errors: 2
• Warnings: 5 → Treated as errors
• Score: 85/100

❌ FAILED - 7 issues found (strict mode)

### Example 3: Auto-Fix

USER: /spec-validation specs/auth-spec.md --fix

SKILL OUTPUT:

Spec Validation with Auto-Fix

Fixes Applied

Fix	Location	Change
Format	REQ-001	Added ID prefix
Format	TC-003	Standardized status
Template	TC-005	Added missing sections

Remaining Issues

Type	Count
Errors	1 (manual fix needed)
Warnings	3

✅ 5 issues auto-fixed ⚠️ 4 issues require manual review

Best Practices

1. Validate Early - Check specs before implementation
2. Use Templates - Standardize spec format
3. Fix Immediately - Address errors right away
4. Review Warnings - Don't ignore warnings
5. Automate - Run validation in CI/CD

Integration

This skill integrates with:

• spec-traceability: Combined coverage validation
• coverage-mapping: Map specs to coverage
• Jira/Azure DevOps: Import validation rules
• CI/CD: Block PRs on validation failure
