Use when writing TypeScript code, reviewing TS implementations, or making decisions about type declarations, function styles, or naming conventions - comprehensive house style covering type vs interface rules, function declarations, FCIS integration, immutability patterns, and type safety enforcement.
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 House Style ## Overview Comprehensive TypeScript coding standards emphasizing type safety, immutability, and integration with Functional Core, Imperative Shell (FCIS) pattern. **Core principles:** - Types as documentation and constraints - Immutability by default prevents bugs - Explicit over implicit (especially in function signatures) - Functional Core returns Results, Imperative Shell may throw - Configuration over decoration/magic ## Quick Self-Check (Use Under Pressure) When under deadline pressure or focused on other concerns (performance, accuracy, features), STOP and verify: - [ ] Using `Array<T>` not `T[]` - [ ] Using `type` not `interface` (unless class contract) - [ ] Using math.js for money/currencies/complex math - [ ] Parameters are `readonly` or `Readonly<T>` - [ ] Using `unknown` not `any` - [ ] Using `null` for absent values (not `undefined`) - [ ] Using function declarations (not const arrow) for top-level functions - [ ] Using named exports (not default exports) - [ ] Using `===` not `==` - [ ] Using `.sort((a, b) => a - b)` for numeric arrays - [ ] Using `parseInt(x, 10)` with explicit radix …

How to install
mdr add ed3dai/ed3d-plugins/howto-code-in-typescript@sha256:18fe83cdd2beb927The line at the top of this page pins the label git:20260218.0673566, 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.
