crosscheck skillcheck

Security scan of an AI agent skill or MCP server before install: a malware and prompt injection audit of its files (read, never run). Finds downloads piped to a shell, credential and wallet theft, secrets sent over the network, persistence, hidden Unicode, and instructions aimed at the agent or the scanner. Supply-chain check with a signed receipt keyed to the file hashes; bundles already scanned are free to look up. $0.03.
