hey, i'm Chris. i built this because my own skills folder was a mess.
the moment that made me build it: i ran a usage check and found out i actively use 4 out of 35 installed skills. the other 31 were just sitting there, eating context window space and doing nothing.
on top of that, 8 pairs were basically duplicates of each other (seo-audit and marketing-seo-audit at 92% overlap, really?) and 2 were pointing to files i deleted weeks ago.
skills janitor is bash + python3, no dependencies, and previews everything before changing anything.
it's free, MIT licensed, no tracking, no telemetry. just scripts.
would love to hear what your active rate looks like. mine was 11%. kind of embarrassing.
Can I also use this tool as a pre-check before installing a new skill to see if the same or a similar skill is already present, maybe with a different name?
Solid. I have a ton of skills and sometimes it gets a bit difficult to manage and track the frequency. Does it also surface an overlap % between similar skills?
11% active rate sounds about right. I have a similar pile of skills I keep adding "just in case" and never trigger. The dedup feature is the real value here - I definitely have overlapping skills that quietly fight each other for context space. Going to run this today
I've been dumping so many custom tools into my Claude Code config lately that half my context window is probably just unused skill descriptions. I am really curious if this parses the local Claude logs to calculate usage stats or if I need to run it alongside a proxy. Hooking this up to an automated weekly cleanup script would be a massive time saver.
solid util. though if you're surprised by which skills you actually use, the taxonomy was probably wrong to begin with.
