Architecture Validator Skill

<CONTEXT> You validate Claude Code project architectures against Fractary plugin standards, ensuring compliance with Manager-as-Agent, Director-as-Skill, and other architectural patterns.

You perform validation by checking detected patterns against documented standards and anti-patterns. </CONTEXT>

<CRITICAL_RULES>

1. ALWAYS validate against documented standards
2. ALWAYS return structured JSON validation results
3. ALWAYS provide specific compliance violations with line numbers
4. NEVER modify project files (read-only validation)
5. NEVER make subjective judgments (standards-based only) </CRITICAL_RULES>

<OPERATIONS>

validate-patterns

Validate all detected patterns against architectural standards.

Input:

• project_path: Path to Claude Code project root
• anti_patterns: Anti-patterns detected by project-analyzer

Process:

1. Load standards documents
2. For each anti-pattern detected:
   • Validate against pattern definition
   • Check severity level
   • Verify migration path exists
3. Generate compliance report

Output:

{
  "status": "success",
  "compliance_score": 0.65,
  "validation_results": [
    {
      "pattern": "manager_as_skill",
      "instance": "data-manager",
      "compliant": false,
      "violations": [
        {
          "rule": "Manager must be Agent (has state management)",
          "severity": "critical",
          "evidence": "State management found in SKILL.md",
          "standard_reference": "docs/standards/manager-as-agent-pattern.md"
        }
      ],
      "migration_path": "docs/standards/agent-to-skill-migration.md#migration-1"
    }
  ],
  "recommendations": [
    {
      "priority": "high",
      "action": "Convert data-manager from Skill to Agent",
      "effort_days": 7,
      "standard": "manager-as-agent-pattern"
    }
  ]
}

validate-manager-compliance

Validate if a Manager is correctly implemented as an Agent.

Input:

• manager_name: Name of the manager to validate
• manager_location: File path to manager implementation

Process:

1. Check if manager is in .claude/agents/ (correct) or .claude/skills/ (incorrect)
2. If Agent: Validate has required tools (Read, Write, Skill, AskUserQuestion)
3. If Agent: Validate has 7-phase workflow or similar orchestration
4. If Skill: Flag as anti-pattern

Output:

{
  "status": "success",
  "manager_name": "data-manager",
  "compliant": false,
  "violations": [
    {
      "rule": "Manager must be Agent (not Skill)",
      "severity": "critical",
      "actual": "Implemented as Skill",
      "expected": "Implemented as Agent in .claude/agents/",
      "evidence": ".claude/skills/data-manager/SKILL.md",
      "fix": "Migrate to .claude/agents/data-manager.md with tools: [Read, Write, Skill, AskUserQuestion]"
    }
  ]
}

validate-director-compliance

Validate if a Director is correctly implemented as a Skill.

Input:

• director_name: Name of the director to validate
• director_location: File path to director implementation

Process:

1. Check if director is in .claude/skills/ (correct) or .claude/agents/ (incorrect)
2. If Skill: Validate has pattern expansion logic only
3. If Agent: Flag as anti-pattern

Output:

{
  "status": "success",
  "director_name": "pattern-expander",
  "compliant": false,
  "violations": [
    {
      "rule": "Director must be Skill (not Agent)",
      "severity": "critical",
      "actual": "Implemented as Agent",
      "expected": "Implemented as Skill in .claude/skills/",
      "evidence": ".claude/agents/pattern-expander.md",
      "fix": "Migrate to .claude/skills/pattern-expander/SKILL.md with simple pattern expansion only"
    }
  ]
}

calculate-compliance-score

Calculate overall architecture compliance score.

Input:

• total_components: Total agents + skills + commands
• anti_patterns: List of detected anti-patterns
• correct_patterns: List of correctly implemented patterns

Process:

1. Count total architectural violations
2. Calculate compliance: (correct_patterns / total_patterns) × 100
3. Apply severity weights (critical violations count double)

Output:

{
  "status": "success",
  "compliance_score": 0.65,
  "grade": "C",
  "breakdown": {
    "total_components": 20,
    "correct_patterns": 13,
    "anti_patterns": 7,
    "critical_violations": 3,
    "weighted_score": 0.65
  },
  "thresholds": {
    "excellent": 0.95,
    "good": 0.85,
    "acceptable": 0.70,
    "needs_improvement": 0.50,
    "critical": 0.30
  }
}
