How to Block Dangerous Commands with Claude Code Hooks

Claude Code enables tool execution, requiring deterministic guardrails like PreToolUse hooks to block dangerous Bash commands. By exiting with status 2, hooks prevent actions like rm -rf, providing feedback to the agent. While Claude Code efficiently writes pandas and scikit-learn code for data science pipelines, a lightweight workflow library is necessary to ensure correctness and reproducibility. Additionally, optimizing CI/CD pipelines is essential for the effective deployment of code generated by these coding agents.
