TypeScript strict patterns and best practices

Prerequisites: a TypeScript project the agent can read and refactor (ideally strict mode) — the skill is a pattern guide, not software to install Install "TypeScript strict patterns and best practices" for me. It gives my agent @gentleman-programming's strict TypeScript discipline: const object first with as const, type extracted from it (no direct union types), flat interfaces with nested objects as dedicated interfaces, never any (unknown/generics/type guards instead), the full utility-type kit (Pick, Omit, Partial, Required, Readonly, Record, Extract, Exclude, NonNullable, ReturnType, Parameters), and import type conventions — every rule shown as always/never with code. MIT-licensed. Repository: https://github.com/gentleman-programming/gentleman-skills/blob/main/curated/typescript/SKILL.md 1. Fetch the SKILL.md file (and any helper files) from the repository path into a temporary folder and summarize what it does in one or two sentences. 2. Safety check: review the SKILL.md for anything suspicious (unexpected network calls, shell commands, credential harvesting). This repo should contain zero secrets in code. Verify that holds here; STOP on any red flag and tell me. 3. Install it as a skill: copy SKILL.md and its helper files into the agent's skills directory, in a folder named "typescript". 4. Verify with no network calls: frontmatter valid, files in place. 5. Report what was installed, where, and what I still need to do myself (e.g. point the agent at my TypeScript project or file; nothing else — it's a pattern guide). GitHub is optional: if I have a GitHub account or the gh CLI, you may use it; otherwise public access is fine. Never require it unless it's in the prerequisites above. Rules: don't touch anything outside the temp folder and the install target. If anything looks off, stop and ask me.
