Nifty Generated
Mark generated files in the Explorer, warn before anyone (or any AI agent) edits them, and optionally make them read-only.
Maintained. No sign-in. No telemetry. Works in VS Code, Cursor, Windsurf, VSCodium and other editors that use Open VSX.
Why
API clients, protobuf code, GraphQL types, Prisma clients, lockfiles: generated files look like normal code, and it's easy for you, a teammate or an AI agent to "fix" one, only for the change to vanish the next time it's regenerated. VS Code has no way to show which files are generated (#15370).
Features
- Knows what's generated, automatically:
.gitattributes rules with linguist-generated (the same markers GitHub uses to collapse generated files in pull requests), including nested .gitattributes and -linguist-generated exceptions.- File headers such as
@generated, DO NOT EDIT, auto-generated, and Go's standard // Code generated … DO NOT EDIT.
- Your own patterns, e.g.
*.pb.go, prisma/client/**, *.generated.ts.
- Visible at a glance. Generated files get a faded G badge in the Explorer, and a Generated padlock appears in the status bar when you open one.
- Stops accidental edits. The first time a generated file changes in a session, whether you typed it or an AI agent did, you get a warning with a one-click Undo Changes.
- Read-only if you want. Turn on
nifty.generated.readOnly and generated files open read-only.
- Keep AI agents out. Add Generated Files to an AI Ignore File writes the list to
.cursorignore, .aiignore, .codeiumignore or .geminiignore, in a managed block that updates in place and leaves your own entries alone.
- List Generated Files shows them all in a quick-pick.
- Works in the browser on vscode.dev and github.dev.
