I don't think any recruiter has a strong expectation that candidates will do this. However, I would do this from time to time, especially where (i) the skill is more unique/impressive, (ii) is demonstrated by a more unique/impressive achievement, or (iii) where the skill is particularly relevant for the day to day tasks of a trainee solicitor (think drafting, researching, project management, legal analysis etc).However, take care not to be repetitive as to the skills you mention. Furthermore, I would advise to only tie your responsibilities to skills sparingly. The more you do it, the less impactful each inference of skill is, and overuse can also impact the flow and structure of your writing.
