Show HN: Bash Script Tools – front end for shellcheck and shfmt with AI autofix (github.com)

Bash Script Tools is a small web-based front end that bundles shfmt (formatter) and shellcheck (linter) with both standard and AI-powered autofix capabilities. Run ./bash-script-tools to start a local server and open the UI in your browser (default http://localhost:8085). It applies shfmt for consistent formatting, uses shellcheck to surface warnings and errors, can apply shellcheck’s built-in automatic fixes, and — optionally — uses an AI model (Groq) to propose and apply fixes for issues shellcheck can’t auto-resolve. This matters because it streamlines an often-frictional workflow for shell script maintenance: interactive linting, one-click formatting, and an experimental AI “autofix” to tackle nuanced or context-sensitive problems. It’s configurable via environment variables (PORT, GROQ_API_KEY, GROQ_MODEL_ID — default shown as openai/gpt-oss-120b — and custom paths for shfmt/shellcheck), runs locally, and is MIT-licensed. Important caveat: AI fixes can be helpful but are not guaranteed correct, so changes should be reviewed and tested before deployment. For teams or CI pipelines looking to reduce shell script debt and speed up remediation, this tool offers a lightweight, extensible way to combine deterministic linters with generative assistance.
