Show HN: A Claude Code plugin that catch destructive Git and filesystem commands (github.com)

A new Claude Code plugin has been introduced as a safety measure against destructive Git and filesystem commands, responding to earlier incidents where commands like `rm -rf ~/` led to significant data loss. This plugin replaces vague documentation with mechanical enforcement by utilizing hooks to prevent the execution of harmful commands. The plugin supports the specification of deny rules for certain Bash commands, although these rules are based primarily on prefix matching, which has limitations in detecting nuanced safety violations. Significantly, this plugin utilizes semantic command analysis to deeply understand command arguments and flag combinations, allowing it to differentiate between safe and dangerous operations. For instance, it analyzes commands that might appear benign, such as `git checkout --` which discards uncommitted changes, and blocks them while providing contextual explanations. The plugin can also enforce stricter modes to prevent the execution of ambiguous commands and automatically redact sensitive information from logs. This development is a major step forward in enhancing safety protocols within AI-driven environments, addressing the growing concern of AI agents mishandling critical system commands.
