Single-file Python CLI tools for code health, testing, documentation, and git hygiene. Drop, run, done.
If any of these sound familiar, we built PyTool for you.
Previous developer left. No docstrings. No README. No tests. You need to understand 40 files before you can change one line safely.
→ DocString + ReadMeReady + PyMetrics map the whole project in minutes, not days.
You know the code needs cleaning but every change might break something. No tests. No metrics. No idea what depends on what.
→ TestScaffold + DupeFinder + CleanImports build the safety net, then refactor with confidence.
47 stale branches. Commit messages like "fix" and "asdf." Large files bloating the repo. No naming conventions. Nobody wants to touch it.
→ GitPulse + BranchLint audit the whole repo and give you a cleanup plan in one run.
TODOs everywhere. FIXMEs from 2023. That one HACK comment you swore was temporary. You need visibility on what you owe your codebase.
→ TodoLens scans 30+ languages, ranks by priority, scores your total technical debt.
You fix something, it breaks again. Copy-pasted code in 6 places means fixing the same bug 6 times. Type hints missing so errors only show up at runtime.
→ DupeFinder + TypeStub eliminate the duplication and catch type errors before your users do.
