When the user wants to codify a repeatable code generation pattern into a jig recipe — design variables, choose operations (create/inject/patch/replace), write Jinja templates, and validate the result. Use when someone says "I keep writing this same boilerplate", "make a recipe for X", or wants to turn a manual edit into an automated pattern.
When the user needs to chain multiple jig recipes into a multi-step workflow with conditional execution and shared variables. Use when a pattern spans multiple files that need coordinated creation and modification, like scaffolding an entire endpoint or a full feature slice.
Scaffold queryset/manager/selector layers and wire view reads through selector entrypoints with jig.
Generate two-step rollout-safe Django migrations plus model-field patching using jig.
Insert consistent method/step structured logging lines into target functions using jig.
Write deterministic service tests with stable fixtures and boundary mocks without using jig.
