Use when adding domain logic (types + service interface + implementation) for a resource without HTTP — typically because the route is handled differently (worker, scheduled job, internal-only)

Use when adding a complete resource to an existing magic-based service — emits migration, types, service layer, and route layer in one pass
Use when bootstrapping a brand-new microservice on github.com/tink3rlabs/magic — clones the service template, applies wizard answers, runs a smoke build
Use when the user asks to scaffold or extend a magic-based service and the right cast sequence is ambiguous — runs a question tree and emits a cast plan
Use when a cast needs to verify whether a package, type, or middleware exists in github.com/tink3rlabs/magic — the in-bounds surface for spellcasting templates
Use when modifying an existing resource on a magic-based service — add a column, add a filter, add a role guard, add soft-delete, swap a storage adapter — enforces DTO-completeness on every field change
Use when a request involves creating, scaffolding, or extending a microservice built on github.com/tink3rlabs/magic — establishes which cast to invoke and the magic-only capability boundary

Emits the domain layer for a resource — types DTO + service interface + storage-backed implementation + table-driven test. No HTTP wiring.

Service layer uses storage.StorageAdapter only (no project-specific storage helpers). Lucene filters pass through to storage.Search — the adapter parses and evaluates the raw Lucene string. Use mql.NewParser(input).Parse() only when you need in-process AST evaluation (validation, transformation, inspection). See magic-capabilities.
