The **textlint-rule-ja-no-weak-phrase** is a plugin for the textlint linting tool that detects and disallows vague or weak Japanese expressions—such as “かもしれない”, “と思う”, and other phrases that merely suggest possibility. It is aimed at writers, editors, and developers who need to enforce a more assertive, “statement‑like” style in Japanese documentation, academic papers, or any prose.
