# X_CLI_OUTBOUND_UNDECLARED

## Means

a non-test `packages/cli/src` file spells a host not on the allowlist

## Typical cause

`x` sends nothing anywhere, and a host literal nobody wrote a reason for is how telemetry or an update check arrives. Every `scheme://host` in a string literal is read (comments are not); names no machine answers for are exempt — `.invalid`, `.test`, `.example`, `example.com`/`.net`/`.org`, `localhost`, loopback

## Fix

delete the URL (an example takes `app.example.com`), or add a row with its `why` to `CLI_OUTBOUND_ALLOWLIST` in `scripts/cli-outbound.ts`, then `bun run scripts/cli-outbound.ts --json`
