run-pre-commit-checks

Run three npm commands in sequence: npm run lint for ESLint rules, npm run compile-tests for TypeScript type checking, and npm run unittest for Mocha unit tests. All three must pass before running git commit.

Run npm run lint -- --fix to automatically correct fixable issues such as import ordering. For remaining errors like no-unused-vars, remove the variable or prefix it with an underscore.

It compiles the test code to detect TypeScript type errors, missing imports, type mismatches, and strict null check violations. Output goes to the out/ directory and is not used for production builds.

This error occurs under strict null checks when a value may be undefined at the point of use. Fix it by adding a null check, using optional chaining, or narrowing the type with a guard.

They should never be skipped. The checks catch type errors that would break the extension, style inconsistencies, and regressions, and they are also enforced by CI on every pull request.
