validate-before-bash

What problem does it solve?

This Skill prevents common build and type-checking failures by automatically verifying that the necessary tools, configuration files, and dependencies are in place before executing commands like tsc, dart analyze, flutter build, pytest, or cargo build.

Core Features & Use Cases

• Pre-validation Checks: Verifies tool installation, presence of configuration files (e.g., tsconfig.json, pyproject.toml, Cargo.toml), and installed dependencies (e.g., node_modules, .venv).
• Language Detection: Automatically detects the project's language (TypeScript, Python, Dart, Rust) or accepts an explicit language argument.
• Use Case: Before running npm run build in a TypeScript project, you can run this skill to ensure Node.js, npx, tsconfig.json, and node_modules are all correctly set up, preventing cryptic errors later.

Quick Start

Run the preflight script to check the build environment for the current project.
