Use when designing or repairing TypeScript domain models, public API types, narrowing, generic relationships, mapped and conditional types, utility types, or inference; representing valid states, deriving types from values, fixing assignability errors, or checking positive and negative compile examples. Use typescript-language-runtime for runtime parsing and execution compatibility.
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 Type Modeling Express the real contract with the smallest type model that makes misuse visible. ## Establish concrete requirements 1. Inspect the existing types, call sites, compiler version, and effective compiler options. 2. Write one valid use, one invalid use, and the value or state each should produce. Include missing, null, empty, or readonly cases when relevant. 3. Identify what is known at compile time and what must be checked at runtime. 4. Identify relationships between inputs and outputs before introducing type parameters. 5. Preserve public compatibility unless the requested change explicitly includes migration. Read [type-design-decisions.md](references/type-design-decisions.md) when choosing a representation, utility, constraint, or recursive transformation. ## Build the model in layers 1. Model finite states or alternatives with a discriminant. Put variant-specific required fields on the corresponding variant. 2. Use an interface or object type for a coherent shape. Choose declaration merging only when open extension is intended. …

How to install
mdr add lu1sdv/skillsmd/typescript-type-modeling@sha256:203b41f39a81cb16The line at the top of this page pins the label git:20261029.c763ba7, 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.
