Type-first TypeScript coding practices — designing types before implementation, making illegal states unrepresentable with discriminated unions, runtime validation with Zod at system boundaries, and module organization (single-function modules, barrel files, encapsulation). Use when starting a new feature by asking what the types should look like first, spotting an interface with too many optional fields that let impossible combinations compile, or deciding how to validate data coming from…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# TypeScript Practices Workflow-level habits: design types first, make bad states impossible to construct, validate at the boundary where untyped data enters, and organize modules so the type-first discipline stays easy to keep up. ## Mindset Design the types before writing the implementation — a type is a specification the compiler checks on every subsequent change, and writing it first forces the impossible states question to be answered up front rather than discovered later as a bug. An interface with many optional fields is usually a discriminated union that hasn't been modeled yet: if `data` and `error` can theoretically both be set, that combination will eventually occur, and the fix is a type that excludes it, not a runtime check that catches it after the fact. Runtime validation belongs at the boundary — the one place untyped data (an API response, form input, an environment variable) enters the typed world — not scattered through the code that consumes it; validate once there, and let the type system carry the guarantee everywhere downstream. ## When to Apply Use this skill when: …

How to install
mdr add pantheon-org/tekhne/typescript-advanced-practices@sha256:90dd5c1e43076474The line at the top of this page pins the label git:20260923.7852cb4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
