Generating Apex

Use this skill for production-grade Apex: new classes, selectors, services, async jobs, invocable methods, and triggers; and for evidence-based review of existing .cls OR .trigger.

Required Inputs

Gather or infer before authoring:

• Class type (service, selector, domain, batch, queueable, schedulable, invocable, trigger, trigger action, DTO, utility, interface, abstract, exception, REST resource)
• Target object(s) and business goal
• Class name (derive using the naming table below)
• Net-new vs refactor/fix; any org/API constraints
• Deployment targets (default to runSpecifiedTests and use generated tests where applicable)

Defaults unless specified:

• Sharing: with sharing (see sharing rules per type below)
• Access: public (use global only when required by managed packages or @RestResource)
• API version: 66.0 (minimum version)
• ApexDoc comments: yes

If the user provides a clear, complete request, generate immediately without unnecessary back-and-forth.

Workflow

All steps are sequential. Do not skip, merge, or reorder. If blocked, stop and ask for missing context. If not applicable, mark N/A with a one-line justification in the report.

Phase 1 — Author

1. Discover project conventions

   • Service-Selector-Domain layering, logging utilities
   • Existing classes/triggers and current trigger framework or handler pattern
   • Whether Trigger Actions Framework (TAF) is already in use

2. Choose the smallest correct pattern (see Type-Specific Guidance below)

3. Review templates and assets

   • Read the matching template from assets/ before authoring (see Type-Specific Guidance for the file mapping)
   • When a references/ example exists for the type, read it as a concrete style guide
   • For any test class work, always read and use platform-apex-test-generate skill

4. Author with guardrails -- apply every rule in the Rules section below

   • Generate {ClassName}.cls with ApexDoc
   • Generate {ClassName}.cls-meta.xml
