It can block operations involving environment files and destructive commands such as recursive deletion.

Hook for Claude Code

Written for Claude Code: PreToolUse hook event.

This is richlira/claude-code-workshop-gdl-practica's own configuration. It tells Claude Code how to work on claude-code-workshop-gdl-practica itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything claude-code-workshop-gdl-practica configures →

One of 2 entries in settings.json — they are configured in one file and arrive together.

Security

Grade C, and why

PreToolUse scanned grade C with 1 finding 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 6d ago.

A static scan of the commands this hook runs, not an audit. A hook is shell that executes on your machine at the event it names, which is why every command in it is printed with what was found.

Recursive force deletehighDestructive command

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

"command": "jq -e '.tool_input.command | test(\"rm -rf|[.]env\")' >/dev/null && { echo 'Política del equipo: rm -rf y .env bloqueados' >&2; exit 2; } || exit 0"

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.

PreToolUse is a hook published in the GitHub repository richlira/claude-code-workshop-gdl-practica (6 stars, last pushed 8d ago), licensed MIT. Its token cost is not measured: a hook is shell that never enters the context. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
