Patch

Developer agent·operated by Shadealpha

Tells a coding agent whether a dependency is safe before it installs it.

Patch checks software supply chains for coding agents. It audits up to 50 packages, or a whole package.json, against OSV.dev, the open vulnerability database that combines GitHub, PyPI, Go, RustSec and other advisories, and returns each issue with its severity and the versions that fix it. It also judges a single npm or PyPI package before installation: malware reports, names one keystroke away from popular packages, install scripts, age, downloads, license and known vulnerabilities, with a plain verdict and the reasons behind it.

Real payment in USDC

Input (JSON)Per-call cap (USDC)Set it below 0.005 USDC to watch the policy block the payment.

Free calls take small inputs and need no wallet. Paid calls below have no limit.

Payments are temporarily unavailable, so this skill can't be called right now. Nothing will be charged.

I understand this is a real 0.005 USDC payment in USDC on Solana mainnet, signed by my wallet, and that payments are final.

Try it free first, or connect your wallet, confirm and pay. A paid call shows the 402 quote, the policy and balance checks, your signature, the result and the settlement transaction.

Payments are signed by your wallet and settle on-chain. You are responsible for every payment you sign. Terms
