omnistudio-callable-apex-generate

Generates and reviews Salesforce Industries Common Core (OmniStudio/Vlocity) Apex callable implementations. Build secure, deterministic System.Callable classes with a 120-point scoring rubric and migration guidance from legacy VlocityOpenInterface implementations.

Features

• Callable Generation: Create System.Callable classes with safe action dispatch
• Callable Review: Analyze existing callable implementations for risks and fixes
• 120-Point Scoring: Validation across 7 callable-specific categories
• VlocityOpenInterface / VlocityOpenInterface2 Support: Phase 2 contract mapping and Phase 3 implementation patterns for invokeMethod(String methodName, Map<String, Object> inputMap, Map<String, Object> outputMap, Map<String, Object> options)
• Migration Guidance: Patterns for moving from VlocityOpenInterface/VlocityOpenInterface2 to System.Callable
• Testing Examples: Test class patterns for actions, errors, and bulk inputs

Quick Start

1. Invoke the skill

Skill: omnistudio-callable-apex-generate
Request: "Create a callable implementation for Order actions with createOrder and cancelOrder"

2. Answer requirements questions

The skill will ask about:

• Industries entry point (OmniScript, Integration Procedure, DataRaptor)
• Action names (strings passed into call)
• Input/output contract (required keys, response shape)
• Data access needs and security expectations

3. Review generated code

The skill generates:

• Callable class with explicit switch on action
• Consistent response envelope
• Test class examples for action coverage and error paths

Bundled Examples

• examples/Test_QuoteByProductCallable/ — read-only callable example with SOQL and test coverage
• examples/Test_VlocityOpenInterfaceConversion/ — migration pattern from legacy VlocityOpenInterface
• examples/Test_VlocityOpenInterface2Conversion/ — migration pattern from VlocityOpenInterface2

Scoring System (120 Points)

Category	Points	Focus
Contract & Dispatch	20	Explicit actions, switch on, versioned strings
Input Validation	20	Required keys, type coercion, null guards
Security	20	CRUD/FLS checks, with sharing, stripInaccessible
Error Handling	15	Typed exceptions, consistent errors
Bulkification & Limits	20	No SOQL/DML in loops, list inputs
Testing	15	Positive/negative/contract/bulk tests
Documentation	10	ApexDoc for class and action methods

Thresholds: ✅ 90+ (Ready) | ⚠️ 70-89 (Review) | ❌ <70 (Block)

VlocityOpenInterface / VlocityOpenInterface2

The skill includes design (Phase 2) and implementation (Phase 3) guidance for the Open Interface signature invokeMethod(String methodName, Map<String, Object> inputMap, Map<String, Object> outputMap, Map<String, Object> options). Use this when extending legacy OmniStudio/Vlocity integration points or building dual Callable + Open Interface implementations.
