AI Invisible Instruction Scanner
`inviscan` is a small Go command line tool that scans source trees for invisible, zero-width, bidirectional, format, and unexpected control Unicode characters.
It is intended as a lightweight supply-chain and code-review aid. It can help spot hidden AI instructions, misleading text, or unusual characters in files such as package manifests, build scripts, AI assistant instruction files, README files, and source code.
It does not prove that a package is malicious.
It only highlights characters that deserve review.
