Polymorph

Transform one representation into another entirely — formats, schemas, protocols, or interfaces.

What This Skill Does

This spell is about representation change, not:

Naming changes (same structure, different identifiers)
Execution changes (same code, different runtime)
Architecture changes (new system design)
Duplication (same thing, different place) The key test: Can you point to a source artifact and a target artifact where the same information is expressed in structurally different ways? If yes → Polymorph. In this grimoire, Polymorph is treated as a metaphorical spell with a shipping-now delivery profile. Canonical reference input: Polymorph (spell).

Activate this spell when the user asks to convert, transform, or migrate data, code, or specifications from one representation format to another where the source and target have different structures and require real semantic mapping.
Verbs: "convert", "transform", "translate", "migrate" (between formats)
Explicit format pairs: "CSV to JSON", "Python to JavaScript", "REST to GraphQL", "YAML to HCL", "Swagger to OpenAPI", "Avro to JSON Schema"
Phrases: "preserve the structure but change the format", "map X concepts to Y", "flag what doesn't translate", "equivalent in [target format]"
Scope indicators: "150 test files", "50 components", "entire test suite" (still this spell if it's format conversion at scale)
