speckit-review-types

Type-design review analyzes TypeScript types to identify implicit invariants, evaluate encapsulation boundaries, and recommend improvements for compile-time enforcement. It surfaces weak state constraints in domain models to prevent subtle bugs in large codebases.

Run a type-design review by providing a representative module from your monorepo. The review assesses invariant clarity, checks internal state exposure, and produces a prioritized backlog of actionable type-improvement tickets for your packages.

Yes, static analysis of type designs discovers implicit invariants and state transitions embedded in interfaces. It evaluates whether current types enforce constraints at compile-time and flags unprotected internal mutations for correction.

Yes, the type-design review applies across large TypeScript codebases. It scales to monorepos with dozens of packages, analyzing domain models to surface weak invariants and generate actionable recommendations for boundary definitions.

You need a type-design review when implicit invariants cause subtle bugs or when domain models lack compile-time enforcement. It identifies weak state constraints, evaluates encapsulation exposure, and proposes concrete changes to improve type fidelity.
