README
Agent Skills Manager
Every skill, plugin and MCP server your coding agents load, in one list on your Omarchy bar.
Claude Code, OpenCode and Codex each keep theirs somewhere else — three sets of skill roots, three config files, and connectors that live nowhere on disk at all. Some of it is the same skill symlinked into two places, paid for twice. None of the three will tell you what the other two are loading.
This widget is that view: one searchable list of everything all three can load, with what each item costs you in tokens on every turn, which agent can see it, and the command that invokes it — on your clipboard, in the spelling that particular agent expects.

The mark is what you click. Beside it the bar can carry one figure, and the one worth carrying is above: what every skill listing adds to every turn before you have typed a word.
It is the figure for the agent you are actually running — three agents read one disk and are charged three different bills, so a single number was never honest. The helper finds which of them has a live process straight out of `/proc`, without starting anything, and prints that agent's bill; two of them up prints the two added together. The default is the mark alone, because a bar is contested space; leave the label off and nothing runs at all until you open the panel.
An Omarchy **Quattro** shell plugin (`bar-widget`). It needs `omarchy-shell` and `python3`, which a stock Omarchy install already has.
Install
omarchy plugin add https://github.com/oliwier-xiao/agent-skills-manager.git --enable
`--enable` puts it straight on the bar and asks which side you want it on. Leave the flag off to install it disabled, read the code first, and turn it on later with `omarchy plugin enable oliwier.agent-skills-manager`.
Update
omarchy plugin update oliwier.agent-skills-manager
omarchy restart shell
The restart is not optio
