Probably, textlint just ignore .bib file. It is not the problem of a rule.

npx textlint --rule textlint-rule-no-dead-link .\ref.bib .\ref.md --debug

textlint support markdown and text by default. https://textlint.github.io/docs/configuring.html#plugin https://github.com/textlint/textlint/wiki/Collection-of-textlint-rule#plugin-list You need to get a plugin that support bib format. However, I don't know where that is.

You can force to resolve bib file by using following textlintrc configuration. But, It will cause false-positive.

{
    "plugins": {
        "@textlint/text": {
            "extensions": [".bib"]
        }
    }
}
