Typescript Anti Patterns

Category: Engineering  ·  Sub-category: languages  ·  Last updated:
lang:typescripttype:audittype:review
This skill should be used when reviewing TypeScript code for anti-patterns, when code contains unsafe practices, when identifying common TypeScript mistakes, when auditing AI-generated TypeScript code, or when enforcing production-grade TypeScript standards. Trigger on: "review TypeScript code", "TypeScript anti-patterns", "unsafe TypeScript", "type assertion smell", "any type misuse", "non-null assertion", "TypeScript code review", "AI generated TypeScript", "TypeScript best practices audit", "code smells TypeScript", "silent catch", "type widening", "generic soup", "mutable exports", "enum pitfalls", "numeric enum", "TypeScript security review", "unsafe cast".

From the source SKILL.md

These patterns represent the most common ways TypeScript's type safety is subverted in production code — including patterns specifically introduced by AI coding assistants. Recognizing and eliminating them is essential for maintaining a trustworthy type system.

Typescript Anti Patterns is a community-contributed Claude Code skill in the languages sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/typescript-anti-patterns/ and loads when your prompt matches the skill's trigger.
