Global Skills

Agent Skills located in skills/ are less coding specific, and are designed for usage across multiple tools.

This repo uses mise dotfiles to link each skill into both shared and Claude-specific global skill directories:

mise dotfiles apply

The relevant config lives in mise.toml:

[dotfiles]
"~/.agents/skills" = { source = "skills", mode = "symlink-each" }
"~/.claude/skills" = { source = "skills", mode = "symlink-each" }

Alternatively, install skills with the Skills CLI:

npx skills add ahstn/pi
npx skills add ahstn/pi --skill code-review-and-quality
