Overview

Hanzo Skill (@hanzo/skill) is a TypeScript CLI tool for installing, managing, and distributing AI agent skills. It clones skill repositories to ~/.hanzo/skills/ as the canonical source of truth, then symlinks them into every supported agent directory (Claude Code, Cursor, Codex, Openclaw, Hanzo Bot). Zero dependencies beyond Node.js standard library.

Why Hanzo Skill?

Single source of truth: ~/.hanzo/skills/ holds all skill repos; agents see symlinks

Multi-agent sync: One add command makes skills available to Claude, Cursor, Codex, Openclaw, and Hanzo Bot simultaneously

Git-native: Skills are Git repos -- add clones, re-run pulls latest

Zero config: No auth, no server, just npx @hanzo/skill add org/repo

Tiny: 3 source files, zero runtime dependencies

Tech Stack

Language: TypeScript (ESM)

Runtime: Node.js 18+

Package: @hanzo/skill v1.0.1 on npm

Dependencies: None (uses node:child_process, node:fs, node:os, node:path)

Tests: Node.js built-in test runner (node --test)

When to use

Installing shared skill libraries for AI coding agents

Keeping skills in sync across Claude Code, Cursor, Codex, and Hanzo Bot

Distributing organizational skill packs (e.g., hanzoai/skills, bootnode/skills)

Listing or removing installed skill collections

Quick reference

Item	Value
npm package	`@hanzo/skill` v1.0.1
Binary names	`hanzo-skill`, `skill`
Canonical dir	`~/.hanzo/skills/`
Repo	`github.com/hanzoai/skill`
Branch	`main`

Agent Directories (Symlink Targets)

Directory	Agent
`~/.claude/skills/`	Claude Code
`~/.agents/skills/`	Codex, Openclaw
`~/.cursor/skills/`	Cursor
`~/.hanzo/bot/skills/`	Hanzo Bot

Usage

# Install skills from a GitHub repo
npx @hanzo/skill add hanzoai/skills       # Hanzo ecosystem skills
npx @hanzo/skill add bootnode/skills      # Bootnode blockchain APIs
npx @hanzo/skill add luxfi/skills         # Lux Cloud APIs

# Force reinstall (delete and re-clone)
npx @hanzo/skill add hanzoai/skills --force

# List installed skills
npx @hanzo/skill list

# Remove skills and all symlinks
npx @hanzo/skill remove hanzoai-skills

# Show help
npx @hanzo/skill --help

How It Works

Normalize URL: Accepts org/repo, github.com/org/repo, or full HTTPS URL

Clone or pull: git clone --depth 1 to ~/.hanzo/skills/<org>-<repo>/, or git pull --ff-only if exists

Count skills: Walks directory tree counting SKILL.md files and .md skill files

Symlink: Creates symlinks from ~/.hanzo/skills/<name> into each agent skill directory

Remove: Deletes symlinks from all agent directories, then removes the skill directory

Repository Structure

src/
  cli.ts          # CLI entry point (add, remove, list, help)
  index.ts        # Core library (addSkills, removeSkills, listSkills, symlinkToAgents)
  index.test.ts   # Tests (Node.js built-in test runner)
package.json      # @hanzo/skill v1.0.1, type: module, bin: hanzo-skill/skill
tsconfig.json     # TypeScript config (ESM output)

Library API

The package also exports functions for programmatic use:

import { addSkills, removeSkills, listSkills, HANZO_SKILLS_DIR, AGENT_SKILL_DIRS } from "@hanzo/skill"

// Install skills
const result = await addSkills("hanzoai/skills", { force: false })
// result.dirName = "hanzoai-skills"
// result.targetDir = "~/.hanzo/skills/hanzoai-skills"
// result.count = 87 (number of skill files found)
// result.linked = ["~/.claude/skills", ...]

// List installed
const skills = await listSkills()
// [{ name: "hanzoai-skills", path: "...", count: 87 }]

// Remove
await removeSkills("hanzoai-skills")

Exported Functions

Function	Description
`addSkills(url, opts?)`	Clone/pull repo, symlink to agents, return stats
`removeSkills(name)`	Remove skill dir and all agent symlinks
`listSkills()`	List installed skill directories with counts
`symlinkToAgents(name)`	Create symlinks from canonical to all agent dirs
`unlinkFromAgents(name)`	Remove symlinks from all agent dirs
`normalizeGitUrl(input)`	Convert shorthand to full HTTPS clone URL
`extractDirName(input)`	Extract `org-repo` directory name from URL
`countSkills(dir)`	Count SKILL.md and .md skill files recursively

Build and Test

# Install and build
npm install
npm run build

# Run tests
npm test

# Development (watch mode)
npm run dev

Troubleshooting

Issue	Cause	Solution
`git clone` fails	Private repo or no git	Check git auth, install git
Symlink permission error	Restricted home directory	Check permissions on `~/.<agent>/`
Skills not visible in agent	Agent not looking at skill dir	Verify agent reads from its skill directory
Skill count is 0	No SKILL.md or .md files	Repo may use different structure
`--force` needed	Existing clone is dirty	Use `--force` to delete and re-clone

hanzo/hanzo-bot.md - Hanzo Bot (consumes skills from ~/.hanzo/bot/skills/)

hanzo/hanzo-agent.md - Multi-agent SDK

hanzo/hanzo-dev.md - Dev CLI (different tool -- dev is AI agent, skill is package manager)
