Add IRON/OS to Agent Skills

[Luis-Andoin]

Adding IRON/OS to the Agent Skills section, one line.

What it is: a Claude skill for strength training. It interviews you once about your goal, equipment, schedule, injuries and current lifts, writes a training programme you read and approve, then builds a single-file workout app you keep on your phone. Saying what changed in plain words ("my knee has started hurting on split squats", "I can only train three days now") rewrites the programme and the app, and the logged history carries over.

Disclosure, so the review is easy:

• I am the maker.
• Paid, GBP 25 one-off, sold as a zip on Gumroad, and it needs a paid Claude plan separately. Both are stated in the entry.
• Closed source, so the link is the product page rather than a repository, the same shape as the existing conductor, Manus Skills and Firecrawl Skills entries. The star bot will not find a repo for it.
• It is a consumer skill rather than a developer tool, so say the word if that puts it outside the list's scope and I will close this.

Thanks for maintaining the list.
