Validate Plan File

Validate orchestrator plan files to ensure they conform to the expected schema before workers process them.

When to Use

• Before workers read plan files
• After orchestrators create plan files
• When debugging plan file issues
• In quality gates validation

Instructions

Step 1: Read Plan File

Use Read tool to load the plan file.

Expected Input:

• file_path: Path to plan file (e.g., .bug-detection-plan.json, .security-scan-plan.json)

Tools Used: Read

Step 2: Determine Schema

Map file name pattern to appropriate JSON schema.

Schema Mapping:

• .bug-*-plan.json → .claude/schemas/bug-plan.schema.json
• .security-*-plan.json → .claude/schemas/security-plan.schema.json
• .dead-code-*-plan.json → .claude/schemas/dead-code-plan.schema.json
• .dependency-*-plan.json → .claude/schemas/dependency-plan.schema.json
• .version-*-plan.json → base schema (version update workflow)

New Naming Convention (standardized):

• Bug workflow: .bug-detection-plan.json, .bug-fixing-plan.json, .bug-verification-plan.json
• Security workflow: .security-scan-plan.json, .security-remediation-plan.json, .security-verification-plan.json
• Dead code workflow: .dead-code-detection-plan.json, .dead-code-cleanup-plan.json, .dead-code-verification-plan.json
• Dependency workflow: .dependency-audit-plan.json, .dependency-update-plan.json, .dependency-verification-plan.json

Step 3: Load and Parse JSON Schema

Use Read tool to load the appropriate schema file from .claude/schemas/.

Tools Used: Read

Step 4: Validate JSON Against Schema

Validate the plan file content against the loaded JSON schema.

Base Schema Validation (all plan files):

• workflow: String (required, e.g., "bug-management", "security-audit")
• phase: String (required, e.g., "detection", "fixing", "verification")
• phaseNumber: Integer (optional, for sequencing)
• config: Object (required, domain-specific configuration)
• validation: Object (required, with required array of validation criteria)
• nextAgent: String (optional, agent to invoke next)
• timestamp: String (optional, ISO-8601 format)
• metadata: Object (optional, with createdBy, iteration, maxIterations)

Domain-Specific Validation:

Bug Plans:

• config.priority: "critical"|"high"|"medium"|"low"|"all" (required)
• config.categories: Array of bug types (optional)
• config.maxBugsPerRun: Integer (optional, default 50)
• config.verifyOnly: Boolean (optional, default false)

Security Plans:

• config.severity: "critical"|"high"|"medium"|"low"|"all" (required)
• config.categories: Array of vulnerability types (optional)
• config.maxVulnsPerRun: Integer (optional, default 25)
• config.skipSupabaseRLS: Boolean (optional, default false)

Dead Code Plans:

• config.type: "critical"|"high"|"medium"|"low"|"all" (required)
• config.categories: Array of dead code types (optional)
• config.maxItemsPerRun: Integer (optional, default 100)
• config.safeMode: Boolean (optional, default true)

Dependency Plans:

• config.category: "security"|"unused"|"outdated"|"all" (required)
• config.severity: "critical"|"high"|"medium"|"low"|"all" (optional)
• config.maxUpdatesPerRun: Integer (optional, default 10)
• config.updateStrategy: "one-at-a-time"|"batch-compatible"|"all" (optional)

Step 5: Return Validation Result

Return detailed validation result with errors/warnings.

Expected Output:

{
  "valid": true,
  "file": ".bug-detection-plan.json",
  "errors": [],
  "warnings": [],
  "schema": "bug-plan",
  "schemaPath": ".claude/schemas/bug-plan.schema.json"
}

Error Handling

• File Not Found: Return error with file path
• Invalid JSON: Return parsing error with line number if possible
• Schema File Not Found: Return error if schema file missing
• Missing Required Fields: List all missing fields from JSON schema validation
• Invalid Field Types: Describe type mismatches (e.g., expected string, got number)
• Invalid Enum Values: Report when value not in allowed enum list
• Schema Mismatch: Warn if file doesn't match expected schema pattern
• Validation Array Errors: Report missing or invalid validation criteria

Examples

Example 1: Valid Bug Detection Plan

Input:

file_path: .bug-detection-plan.json

Content:

{
  "workflow": "bug-management",
  "phase": "detection",
  "phaseNumber": 1,
  "config": {
    "priority": "all",
    "categories": ["type-errors", "runtime-errors"],
    "maxBugsPerRun": 50
  },
  "validation": {
    "required": ["report-exists", "type-check"],
    "optional": ["tests"]
  },
  "nextAgent": "bug-hunter",
  "timestamp": "2025-10-18T14:00:00Z",
  "metadata": {
    "createdBy": "bug-orchestrator",
    "iteration": 1,
    "maxIterations": 3
  }
}

Output:

{
  "valid": true,
  "file": ".bug-detection-plan.json",
  "errors": [],
  "warnings": [],
  "schema": "bug-plan",
  "schemaPath": ".claude/schemas/bug-plan.schema.json"
}

Example 2: Missing Required Field

Input:

file_path: .security-scan-plan.json

Content:

  "workflow": "security-audit",
  "phase": "scan",
  "config": {
    "categories": ["sql-injection"]

    "required": ["type-check"]
  }
}

Output:

{
  "valid": false,
  "file": ".bug-fixing-plan.json",
  "errors": [
    "Schema mismatch: file pattern suggests 'bug-plan' schema but workflow field is 'security-audit'",
    "Invalid enum value at /phase: 'fixing' not in allowed values ['detection', 'fixing', 'verification'] for bug-plan"
  ],
  "warnings": ["Consider renaming file to match workflow: .security-remediation-plan.json"],
  "schema": "bug-plan",
  "schemaPath": ".claude/schemas/bug-plan.schema.json"
}

Validation

• Validates all required fields present
• Checks field types correctly (string, number, boolean, array, object)
• Validates enum values against allowed lists
• Identifies schema based on file name pattern
• Returns clear error messages with JSON paths
• Handles malformed JSON gracefully
• Validates domain-specific fields (priority, severity, category)
• Checks workflow/phase consistency
• Validates validation criteria arrays (required/optional)
• Handles schema file loading errors

Supporting Files

Located in .claude/schemas/:

• base-plan.schema.json: Base schema for all plan files
• bug-plan.schema.json: Bug management workflow schema
• security-plan.schema.json: Security audit workflow schema
• dead-code-plan.schema.json: Dead code cleanup workflow schema
• dependency-plan.schema.json: Dependency management workflow schema

Integration with Orchestrators

All orchestrators should use this Skill after creating plan files:

## Step 3: Create Plan File

1. Write plan to `.{domain}-{phase}-plan.json`
2. Use validate-plan-file Skill to verify:
   - Input: file_path = ".{domain}-{phase}-plan.json"
   - Check result.valid === true
   - If errors exist, fix plan file and retry
3. Only signal readiness after validation passes

Notes

JSON Schema Validation: This Skill performs full JSON Schema Draft-07 validation including:

• Type checking (string, number, boolean, array, object)
• Required properties
• Enum constraints
• Pattern matching
• Nested object validation (allOf, $ref)
• Array item validation

File Naming Convention: Plan files must follow pattern .{domain}-{phase}-plan.json where:

• {domain}: bug|security|dead-code|dependency
• {phase}: detection|fixing|verification (bugs), scan|remediation|verification (security), etc.

Schema References: Uses JSON Schema $ref for base schema inheritance. All domain schemas extend base-plan.schema.json.
