typescript-common-practice

House skill. This is the TypeScript language baseline that complements software-engineering. It does not replace typescript-type-safety, typescript-async, typescript-testing, javascript-runtime, browser-runtime, or framework-specific skills.

When to load

Load for TypeScript source changes: application code, libraries, CLIs, plugins, build tooling, and typed tests. Do not load for read-only inspection unless TypeScript conventions are themselves the subject.

Load narrower skills only when their concern is material. A synchronous pure refactor does not need the async skill; a type-only change does not automatically need browser-runtime.

Start from the repository contract

Before changing code, inspect the local TypeScript contract:

• tsconfig files and project references;
• package manager and scripts;
• runtime and module mode;
• lint/format configuration;
• test runner and test environment;
• generated-code boundaries.
