missing_reason

An --@alloy-expect-error with no reason.

The directive says a line must hold an error. Write why after the name, --@alloy-expect-error the contract rejects a negative count, and the reason comes back in the message when the line goes clean, so a stale directive is easy to place. --@alloy-ignore takes a reason the same way and never draws this lint. No automatic rewrite: only the author knows the reason.

Set its level in the [lint] table of alloy.toml, or for one file with --@alloy-lint.
