# X_DOC_COMMAND_UNKNOWN

## Means

a page in `wiki/` or `docs/` hands the reader an `x` invocation this build cannot run

## Typical cause

the command, its subcommand, its positional or one of its flags does not exist — a renamed flag (`--from` for `--from-step`), a plural that moved (`x entity` for `x entities`), or a command that never shipped

## Fix

`bun run scripts/doc-commands.ts --json`; `x help --json` lists every command, subcommand and flag
