guard-install now scans GitHub repos before you run them

Hey everyone,

I shared this earlier as a CLI to analyse npm packages before installing.

Since then, I’ve added something I think is even more useful:

👉 You can now scan GitHub repos before cloning or running them

npx guard-install --repo https://github.com/user/repo

Why this matters

There’s a growing pattern (especially in crypto interviews / side projects):

“Clone this repo and run it locally”

Some of these repos:

• access environment variables
• interact with wallets / keys
• make outbound network calls

You don’t always notice what’s happening before you run the code.

What the repo scan does

• Scans files (without executing anything)

• Detects:

  • sensitive data patterns (PRIVATE_KEY, MNEMONIC)
  • crypto/wallet usage
  • network calls
  • shell execution

• Combines signals → gives a risk level (LOW / MEDIUM / HIGH)

• Explains why something might need review

Example

🔐 Sensitive data patterns found
💰 Cryptocurrency functionality
🌐 Network activity detected

Risk: MEDIUM — Sensitive domain with multiple relevant signals

Still early, but getting more practical now.

Would love feedback on:

• Are these signals useful or noisy?
• What would make you trust a HIGH risk warning?
• Would you use this before running unknown repos?

Thanks!
