typescript-maintainable-design from lu1sdv/skillsmd is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when reviewing or refactoring TypeScript modules and services for excessive coupling, invalid inheritance, broad interfaces, dependency injection, unsafe assertions, mutable shared state, swallowed errors, circular imports, or maintainability and anti-pattern concerns. Apply SOLID through explicit behavior contracts and focused dependencies; tie performance changes to measured workloads and route detailed algorithm, async, and type- system work to specialist skills.
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 Maintainable Design Turn a concrete design problem into a small, behavior-preserving change. Use SOLID to reason about boundaries; judge the result by observable behavior and the cost of the next required change. ## Establish the contract 1. Read the repository instructions, package scripts, compiler configuration, affected callers, and existing tests. Keep the established module/framework conventions unless the task requires changing them. 2. State the current problem and one representative example. Separate a correctness defect from maintainability friction or an unmeasured speed claim. 3. Record input/output types, accepted values, errors, mutation, ordering, and resource lifetime. Distinguish compile-time promises from runtime guarantees. 4. Identify external boundaries: parsed JSON, storage, requests, environment values, plugin callbacks, and untyped libraries. Track where validation occurs. 5. For a refactor, preserve these contracts. For a bug fix, identify the specific behavior that must change and verify the corrected behavior. ## Select the smallest intervention | Observed pressure | Apply this lens | Prefer this intervention | …

How to install
mdr add lu1sdv/skillsmd/typescript-maintainable-design@sha256:21cf9653095d0a4fThe 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.
