About This Tool

The tool performs language-aware static analysis on source code to detect quality issues such as unused imports, long lines, duplicate code, and inconsistent naming. It supports multiple languages by loading language-specific rule sets and applying them to the provided code. It outputs a prioritized list of issues and offers safe, localized fix suggestions that preserve behavior. Users can run analysis to obtain a clean diff and optional auto-fixes. The core value is to accelerate refactoring, standardize style, and reduce review cycles by surfacing actionable recommendations. It is well-suited for developers, code reviewers, and CI pipelines that enforce code quality gates. Unique differentiators include language-sensitive rule packs, conservative auto-fixes, and granular configuration that can be integrated into existing workflows. The tool also supports batch processing for large repositories and can export patches for version control systems.

Frequently Asked Questions

Find Quick Answers

Which languages are supported and how does parsing work?

The tool supports Python, JavaScript, Java, TypeScript, and more via language-specific parsers. It builds an AST or token stream for each language to enable precise rule application and accurate fix suggestions.

Are changes destructive by default?

No. Analysis produces a non-destructive report by default; auto-fix can be enabled in config to apply safe, localized changes and generate a patch or diff.

Can it integrate into CI workflows?

Yes. It provides CLI and API access, enabling automated runs in CI pipelines and producing structured outputs (issues, diffs, and cleaned code) suitable for reviews.

How are fixes determined and validated?

Fixes are derived from curated rule sets and conservative heuristics. Each recommended change is validated for syntactic correctness and preserved semantics when possible.
