    • Read your context and instructions
    • Compiled the dangerous command linter

    Findings:

    [High] Pipe-to-Shell: Remote content is piped directly to sudo bash.

    • Evidence: curl ... | sudo bash
    • Risk: Unverified remote execution.
    • Alternative: Download script, inspect manually, then run: curl -O [URL] && less [file]

    About this skill

    Safety First for Shell Operations

    The Dangerous Command Linter is a specialized security tool designed for developers and DevOps engineers who want an extra layer of protection before executing shell commands or scripts. It identifies destructive, irreversible, or high-risk operations that could lead to data loss or system instability.

    What it does

    This skill performs a heuristic analysis on shell scripts (.sh, .bash, .zsh, .ps1) and raw CLI strings. It scans for patterns including recursive deletions, force pushes, database drops, permission overrides (chmod 777), and the "curl | sh" anti-pattern. Unlike a standard LLM prompt, it utilizes a dedicated Python scanner and a curated JSON database of dangerous patterns to ensure consistent, rule-based detection.

    Supported Tools & Frameworks

    • Bash, Zsh, and PowerShell scripts
    • Git, Docker, and Cloud CLI commands
    • Standard Linux/Unix system utilities (rm, chmod, chown)
    • Database CLI tools

    Why use this skill?

    While an AI can "guess" if a command is bad, this skill follows a structured audit workflow. It provides a formal report categorizing findings by severity, identifies the exact line of concern, and suggests safe alternatives or remediation snippets. It acts as a pre-execution linting layer for your terminal workflow, reducing the risk of "fat-finger" errors in production environments.
