Can't remember how I landed on it - I was managing skills manually for quite a while. I think I tried another 'skill manager' at some point before I found tessl.
Two aspects I like: skills repository (and versioning, per project), and the easy cli tools to incrementally test and improve my personal skills.
In a world where 'this skill pack will level you UP' bravado abounds, I'm happy that I can use this tool to easily pick out the ones where the author actually tested their skills, and its easy to keep the specific skills I want up to date.
An aspect I haven't explored much, but would love to have is...since the tessl.json skill dependencies are in my repository...if I fire off a remote agent (claude code for web mostly, in my case, but opencode too) it pre installed my tessl deps (including my private repo ones) before tackling the work. I suspect there is a way, just haven't explored...
