Agent Skills & Plugins, installed. Pure bash.
A tiny CLI that installs agentskills.io Agent
Skills and agent-plugins.org Agent Plugins from any git
repo — with dependency resolution and manifest validation, into the .agents/
paths agents like Devin index. No Node.js. No runtime. Just bash + git + jq.
# install — Homebrew
brew install junior/tap/skilla
# …or managed via mise (no Node.js)
mise use -g 'github:junior/skilla[exe=skilla,matching=skilla]@0.4.1'
# …or grab the single script
curl -fsSL https://raw.githubusercontent.com/junior/skilla/v0.4.1/skilla -o ~/.local/bin/skilla && chmod +x ~/.local/bin/skilla
# then
skilla add git@github.com:acme/skills.git --skill nginx # installs nginx + its deps
skilla add --scope user git@github.com:acme/skills.git # user-wide (~/.agents/skills)The agent-skills CLI space is crowded — and almost all of it rides on Node/npx. skilla is deliberately small and runtime-free.
One ~800-line bash script. If you have git and jq, you can install skills — on a server, a CI runner, or a locked-down box.
A skill's requires (frontmatter, or plugin.json requiredSkills) are pulled automatically from the same source — transitively.
Installs agent-plugins.org packages: validates the manifest, keeps the tree intact for ${PLUGIN_ROOT}, and hands you the MCP config with placeholders expanded.
Install into a repo's .agents/skills/ or your home ~/.agents/skills/, tracked in a small JSON registry.
It clones and copies — nothing executes at install time. A skill's scripts only run later, when an agent uses it.
add, update, list, info, remove — registry-scoped, so it only manages what it installed.
Built to verify signed skills before install (on the roadmap), so a catalog can enforce provenance end-to-end.
skilla is a single bash script: it needs only bash, git, and jq —
no Node, no npm, no node_modules, no runtime version to match. Copy one file and go. (Most other
agent-skills CLIs run through npx/Node; skilla doesn't.)
