Like Rock Lee, Kin Tsuchi made her debut during the "Chunin Exams Arc." She is a part of Orochimaru's Team Dosu. And though she and her teammates give Naruto and his comrades a bit of a headache during their brief interaction, she also reveals that her chakra ability isn't that impressive. We get a better glimpse during her fight against Shikamaru in the manga chapter #74 (via Viz Media). Kin relies on throwing needles called senbons with bells and rope attached to them. And that's it. She doesn't display any other special abilities other than having expert accuracy and trickery with her weapons. And that proves to be futile because It doesn't take Shikamaru long to outsmart and defeat her. She plays right into the henchwoman role down to her simple abilities.
The anime version (via Crunchyroll) of her fight against Shikamaru adds a basic Genjutsu ability that leaves Shikamaru slightly more disoriented. Yet the battle still has the same result as its manga counterpart. It's brief and doesn't do much to support Kin's limited chakra abilities. So Kin displays chakra control that's only marginally better than Rock. Potentially, she could have further developed her skills, especially her Genjutsu in the anime. However, we'll never know due to her sudden death in the series. During Orochimaru's fight against the Third Hokage, he sacrifices herself to summon the First and Second Hokages.
