Probably OK. The JEs don't split senses but I think this makes sense.

sankoku senses of 辛気:
[1] （もと関西方言）気がくさくさして、めいるようすだ。暗い。「ー話」
[2] （関西・中部・中国方言) いらだたしい。じれったい。

心気くさい	39	30.0%
心気臭い	91	70.0%
vs.

辛気臭い	15881	70.1%
辛気くさい	6777	29.9%


心気	18376	99.3%　　　<----- this seems more likely to be totally unrelated
心気くさい	39	0.2%
心気臭い	91	0.5%

I encountered this as [1](example below).  More comments at the main 心気 entry.  I think 心気 is clearly its own thing by the ngrams(18376), and by the counts given for 心気くさい(~100), I think this kanji is best hidden under [sK] as a spelling error.

sankoku splits the senses [1] and [2].  I sometimes see these entries were very unrelated glosses are sitting next to each other to avoid splitting senses... In the context I saw this was distinctly nothing to do with annoyance or irritation.

I'm not sure how to interpret sankoku's dialect notes. Note that they are different for [1] and [2].  The もと in （もと関西方言） suggests to me that this *was* kansai-ben, but is now more generally recognized?  Do we note this("formerly kansaiben?") [2] is still recorded as a strictly regional dialect, but is more broad than kansaiben. (関西・中部・中国方言)

The use I encountered was by a young, brash, anime warrior-type character, and I know these figures often get "rough" dialects assigned to them, but I'm not an expert on that.

Frieren: 俺がこの村に来たとき、みんな辛気くさい顔して、竜の恐怖におびえていた。そんな連中がさ、今で幸せそう笑っているんだよ
When I arrived here, all of the villagers wore grim expressions and lived in fear of the dragon. Now those people are smiling happily

==== 
I swapped kanji ordering purely on the ngrams where the kanji form has a 3-1 lead, though くさい was written in kanji where I encountered it.

I don't think "fretful" or the example on the first gloss are helpful. 
Reordered glosses slightly.
