What is a safety pattern in this context?

A safety pattern is a specific regex-based rule used to identify and block potentially dangerous shell commands before they are executed by the Caro CLI.

Can I use this for non-Rust projects?

While the specific implementation examples are tailored for the Caro Rust repository, the threat identification and TDD methodology can be adapted for any security-focused project.

How are risk levels determined?

Risk levels are categorized as Critical (data loss/system destruction), High (dangerous but reversible with backups), and Medium (harmful but limited in scope).

Why does this skill enforce a TDD workflow?

Test-Driven Development ensures that every safety rule is validated against specific threat scenarios before implementation, preventing both security gaps and false positives.

Security & Testing

Guides developers through a rigorous Test-Driven Development workflow for creating and implementing safety patterns in command-line tools.

The Safety Pattern Developer skill facilitates the systematic addition of security rules to the Caro repository by enforcing a strict 6-phase TDD cycle. It assists developers in identifying potential system threats, writing failing test cases, implementing robust regex-based blocking patterns, and verifying them against regressions. This skill is essential for security-conscious developers looking to prevent accidental data loss or system destruction from dangerous shell commands like recursive deletions or disk wipes.
