Developer builds peek tool to

Original: I stopped trusting curl | sh — so I built a tool that reads the script first

Short summary

A developer built peek, a 130-line POSIX shell script that audits remote install scripts before execution, scanning for risky patterns like sudo elevation, destructive file operations, obfuscated payloads, and credential access. peek assigns risk scores and blocks auto-run for dangerous scripts, making the `curl | sh` pattern safer by requiring human review. The tool is open-source, was AI-paired with Claude, and part of a wider suite of infrastructure-independent developer tools.

  • Built a security scanner (peek) that audits shell scripts before execution
  • Scans for risky patterns: sudo, rm -rf, eval, cron jobs, credential access
  • Open-source tool AI-paired with Claude; includes 11 other shell-based dev tools
