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 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 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 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

The authoritative answer to "is X available in github.com/tink3rlabs/magic?". Pinned to v0.17.3. If your magic is newer, prefer upstream and note the drift in your cast output.
NOTE — reconciled against real magic v0.17.3 source on 2026-05-29. Three major corrections vs. previous content:
storage.NewStorageAdapter()does not exist → usestorage.StorageAdapterFactory{}.GetInstance(type, configMap).mql.Parse(string)does not exist → usemql.NewParser(input).Parse(); but service layers should pass raw Lucene tostorage.Search, not call the parser directly.- Migration YAML has no
id:field — the numeric ID is encoded in the filename prefix (0001__create_RESOURCETABLE.yaml). YAML fields aredescription:+migrations: [{migrate: ..., rollback: ...}].
Every cast template references only what's in this surface. If a generated file imports a package not listed here — or imports anything from a project-specific common library that wraps magic — the cast has failed. Revert and use an in-bounds equivalent.

storage.MEMORY | in-process map; no persistence |
storage.SQL | PostgreSQL / MySQL via database/sql |
storage.COSMOSDB | Azure Cosmos DB |
storage.DYNAMODB | AWS DynamoDB |
Config shape (config/default.yaml):

mql.Parse(string) does not exist — use mql.NewParser(input).Parse().
Preferred pattern: service layers pass the raw Lucene string directly to storage.Search(...) and let the adapter parse and evaluate it. Only call mql.NewParser when you need in-process AST evaluation (e.g. to validate, transform, or inspect the query before sending it to storage).
