dangerous-bash-guard

dangerous-bash-guard is a plugin for Claude Code from thapr0digy/skills. Its token cost is not measured, scanned D, original, MIT.

A safety hook that checks Bash commands before they run. It blocks commands that can permanently damage files or systems and asks for confirmation before risky shared or Git operations.

In plain words
What is it for?
It is for guarding commands such as recursive deletion, disk formatting, force-pushing, hard resets, pull-request changes, Kubernetes operations, Terraform changes, and cloud or Docker deletion.
Why use it?
It reduces the chance that an automated agent will erase data, rewrite project history, change cloud resources, or affect shared environments without approval.

Security

Grade D, and why

dangerous-bash-guard scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

What it installs

The manifest is a name and a version. 1 hook travel with it, and installing the plugin installs all of them. Each is measured on its own page, and each can be installed alone.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
