typescript-pro SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
typescript-pro from 12-studio/tackl is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add 12-studio/tackl/typescript-pro@v1.1.0Pins v1.1.0 in mdr.lock. Pin the fingerprint instead.

Implements advanced TypeScript type systems, creates custom type guards, utility types, and branded types, and configures tRPC for end-to-end type safety. Use when building TypeScript applications requiring advanced generics, conditional or mapped types, discriminated unions, monorepo setup, or full-stack type safety with tRPC.
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 Pro ## Core Workflow 1. **Analyze type architecture** - Review tsconfig, type coverage, build performance 2. **Design type-first APIs** - Create branded types, generics, utility types 3. **Implement with type safety** - Write type guards, discriminated unions, conditional types; run `tsc --noEmit` to catch type errors before proceeding 4. **Optimize build** - Configure project references, incremental compilation, tree shaking; re-run `tsc --noEmit` to confirm zero errors after changes 5. **Test types** - Confirm type coverage with a tool like `type-coverage`; validate that all public APIs have explicit return types; iterate on steps 3–4 until all checks pass ## Reference Guide Load detailed guidance based on context: | Topic | Reference | Load When | |-------|-----------|-----------| | Advanced Types | `references/advanced-types.md` | Generics, conditional types, mapped types, template literals | | Type Guards | `references/type-guards.md` | Type narrowing, discriminated unions, assertion functions | | Utility Types | `references/utility-types.md` | Partial, Pick, Omit, Record, custom utilities | …

How to install
mdr add 12-studio/tackl/typescript-pro@sha256:5f5bc47c167f0485The line at the top of this page pins the label v1.1.0, 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.
