Use when implementing or debugging TypeScript language features, typed JavaScript migrations, nullish handling, functions and classes, imports and module boundaries, runtime input validation, or compatibility with Node type stripping and other execution paths. Keep static contracts and JavaScript behavior aligned; use typescript-type-modeling for advanced generic or type-level API design.
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 Language and Runtime Make the code's static contract, emitted or stripped JavaScript, and actual execution agree. ## Establish the execution contract 1. Inspect the relevant source, package manifest, lockfile, tsconfig chain, and existing run/build commands. 2. Record the actual compiler and runtime versions when behavior depends on them. Do not treat a guide's version label as the project's version. 3. Identify the execution path: compiled JavaScript, a bundler, a TypeScript runner, or native Node stripping. 4. Identify ESM/CommonJS boundaries, package exports, import extensions, and target environments before editing imports. 5. State valid inputs, absent values, mutation ownership, and error behavior. Use the surrounding API's conventions unless they cause the reported issue. Read [runtime-compatibility.md](references/runtime-compatibility.md) for module, decorator, feature-support, or Node stripping issues. Route broad toolchain changes to `typescript-tooling-tdd`. ## Implement the smallest coherent change …

How to install
mdr add lu1sdv/skillsmd/typescript-language-runtime@sha256:f89921a222dbc36cThe 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.
