Does it support Biome or only traditional tools like ESLint?

It is designed to be flexible, supporting standard package scripts or falling back to tools like Biome and Vitest if they are present in the environment.

How does it handle pre-existing errors in the codebase?

It follows a specific decision tree: it fixes small pre-existing issues (under 10 lines) in modified files but documents and reports larger issues as separate tasks to avoid scope creep.

Which package managers does this skill support?

The skill automatically detects and supports pnpm, yarn, npm, and bun by checking for their respective lock files.

When is this protocol triggered?

It should be used always after creating new files, modifying existing code, or refactoring, but skipped when only reading code or generating documentation.

What happens if a project is missing a specific script like 'lint'?

The skill uses graceful degradation, marking the step as 'SKIPPED' in the final report while continuing with other available verification steps.

Developer Tools

Automates a mandatory quality assurance workflow including formatting, linting, and testing after any JavaScript or TypeScript code modification.

This skill provides a standardized, automated verification protocol for Claude agents working in JavaScript and TypeScript environments. It ensures that every code change undergoes a rigorous check involving code formatting, linting, type-checking, and regression testing. By detecting package managers automatically and following a strict decision tree for handling pre-existing issues, it maintains high code standards while preventing the introduction of new regressions or style inconsistencies. It is an essential tool for maintaining repository health during autonomous coding tasks.
