In the itemize environment, \item is not considered as the end of the sentence.

[t4t5u0]

This problem occurs when used in conjunction with ja-technical-writing.

In the itemize and description environments, lines beginning with \item are recognized as a single sentence.

I have checked this issue with no-double-joshi and max-length.

I've confirmed that the problem has been reproduced.

@t4t5u0
As you pointed out, the current implementation is incomplete and may be causing these false positives due to problems of parsing.

Normally, if sentences containing the same joshi are punctuated within a paragraph, no problem will be detected, as shown below.
Therefore, it is not a problem with these detection rules, but with this plugin.

$ cat << EOF > sample2.tex
\begin{section}
これはサンプルです。
これはサンプルです。
\end{section}
EOF
$ npx textlint sample2.tex
$ echo $?
0

We will try to solve the problem.
The current workaround is to disable certain detection rules at certain places. textlint-filter-rule-comments will help you.

Thank you for reply. In my environment, rules ignore works too.
