Hair Solutions Co. — AI Toolkit

A vendor-neutral marketplace of Hair Solutions Co. plugins, skills, agents, commands, and MCP servers for Claude Code / Cowork, Codex, Cursor, Gemini CLI, and Google Antigravity. Plugin content is shared; thin client-specific manifests expose it to each supported agent.

• Marketplace slug: hairsolutionsco
• Owner: Vincent Laroche
• Repo: vincent-laroche/hairsolutionsco-ai-toolkit

Install (Claude Code / Cowork)

Cowork: + → Plugins → Add plugin → Add marketplace → enter vincent-laroche/hairsolutionsco-ai-toolkit → Sync, then install any plugin from the list.

Claude Code terminal:

/plugin marketplace add vincent-laroche/hairsolutionsco-ai-toolkit
/plugin install shopify-theme-dev@hairsolutionsco
/reload-plugins

Install (Codex)

codex plugin marketplace add vincent-laroche/hairsolutionsco-ai-toolkit
codex plugin add shopify-theme-dev@hairsolutionsco

Restart Codex after installing or updating a plugin.

Install (Cursor)

Use Install Plugin From Source and enter:

vincent-laroche/hairsolutionsco-ai-toolkit

Cursor reads .cursor-plugin/marketplace.json and each plugin's native .cursor-plugin/plugin.json.

Install (Gemini CLI)

Gemini CLI currently installs one extension root at a time. Clone this repository, then install or link the required plugin directory:

git clone https://github.com/vincent-laroche/hairsolutionsco-ai-toolkit.git
gemini extensions install ./hairsolutionsco-ai-toolkit/plugins/chrome-devtools-mcp

Use gemini extensions link <plugin-directory> during local development.

Install (Google Antigravity)

Clone this repository, then run the non-destructive installer for the required toolkit:

# Preview all skill and MCP changes.
./scripts/install-antigravity-plugin.sh

# Install or update all marketplace plugins.
./scripts/install-antigravity-plugin.sh --apply

The installer namespaces duplicate skill names, adopts identical existing skills, preserves local modifications, backs up Antigravity's MCP configuration before writing, and reports same-name MCP conflicts without exposing config values.
