typescript from xobotyi/cc-foundry is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Write and review TypeScript: the type system, strictness configuration, narrowing, generics, type-level patterns, declaration files, module resolution and `tsconfig`, and the release a project's compiler pins.
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
<prerequisite> Load the `javascript` skill first. Declarations, equality, closures, iteration, promise semantics, and ES module syntax are stated there and are not repeated here. Skipping it produces TypeScript that is type-correct and idiomatically wrong. </prerequisite> A type earns its place by making a wrong program fail to compile. Three biases decide most calls: - **Make the invalid state unrepresentable, then let inference carry the rest.** An annotation that restates what the compiler already infers is noise; a type that admits a state the domain forbids is a defect that will be found at runtime. - **Every escape hatch is a defect report against a type.** `any`, `as`, `!`, and `@ts-ignore` each move a failure from the compiler to production. Reaching for one means the declaration is wrong, and that is where the fix belongs. - **The `tsconfig.json` decides what the compiler catches; the pinned release decides what may be written.** Read both before writing code. ## Compiler Release The `typescript` entry in the project's `package.json` sets the release. Read it before writing code and never reach for …

How to install
mdr add xobotyi/cc-foundry/typescript@sha256:fc7472042ff9a8e0The line at the top of this page pins the label git:20261029.e458a11, 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.
