Install

Skills CLI

npx skills add genlayerlabs/subzeroclaw

Asks which skills and agents to install. Just one: npx skills add genlayerlabs/subzeroclaw --skill subzeroclaw-contribute — add -g for every project.

Claude Code

git clone https://github.com/genlayerlabs/subzeroclawcp -r "subzeroclaw/.claude/skills/subzeroclaw-contribute" ~/.claude/skills/

Copies the subzeroclaw-contribute skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.

Plugin

/plugin marketplace add genlayerlabs/subzeroclaw

Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.

Skills can run code on your machine — read the SKILL.md first.

What it does

In the author's own words, from each skill's SKILL.md.

  • subzeroclaw-contribute

    Develop SubZeroClaw — the single-file ~550-line C agentic runtime. Load this before changing src/subzeroclaw.c or src/test.c: it carries the anti-framework thesis (the goal is NOT to grow), the code map (the loop, config, the shell tool, async compaction), what will and won't be merged, and the build/test loop. To merely run or configure SubZeroClaw, use subzeroclaw-use.

  • subzeroclaw-use

    Run and operate SubZeroClaw — the ~550-line C agentic daemon (skill.md + LLM + shell + loop). Load this to build it, configure it (~/.subzeroclaw/config), write an agent skill, run a task, wire it to an unhardcoded router for routing/cache/compaction, or run it as a systemd service with credential isolation. WARNING: it executes arbitrary shell with no sandbox. To develop the runtime itself, use…

Review before you install

A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
