Install the skills

The MCP server gives your agent the tools. Skills teach it how to use them well: how to build a sheet, run an FBA shipment, query the synced reports, manage Ads, write a Data Kiosk query or make listing images. SellerSheet publishes 11 of them, installed as one bundle — see the skills catalog.

Claude Code — the pluginCopy Anchor Link

/plugin marketplace add sellersheetai/sellersheet-skills
/plugin install sellersheet-skills@sellersheet-marketplace

This installs the whole skill bundle and registers the SellerSheet MCP server. Sign in once: run /mcp, pick sellersheet and approve in the browser — no API key.

Claude — claude.ai and the desktop app: the same pluginCopy Anchor Link

In Customize → Plugins, select Add → Add marketplace and enter sellersheetai/sellersheet-skills. Open SellerSheet Skills and select Add, then connect SellerSheet from the plugin's Connectors tab (steps). The plugin is saved to your Claude account, so Cowork and Claude Code get it too.

Codex and ChatGPT — the same pluginCopy Anchor Link

In the ChatGPT desktop app, where Codex runs: Plugins → Add → Add a marketplace, enter sellersheetai/sellersheet-skills as Source, leave the other fields empty and select Add marketplace. Then select + (Install plugin) on the SellerSheet plugin and connect it when prompted (steps).

With the Codex CLI:

codex plugin marketplace add sellersheetai/sellersheet-skills
codex plugin add sellersheet-skills@sellersheet-marketplace
codex mcp login sellersheet

CodeBuddy — the same pluginCopy Anchor Link

Inside a CodeBuddy session:

/plugin marketplace add sellersheetai/sellersheet-skills
/plugin install sellersheet-skills@sellersheet-marketplace

Then /reload-plugins, and sign in with /mcp. Skills appear namespaced, such as /sellersheet-skills:report-data.

WorkBuddy — the same pluginCopy Anchor Link

In 专家·技能·连接器 → 技能 → 套件, click + (添加市场) and enter sellersheetai/sellersheet-skills, then click + (安装) on sellersheet-skills. Connect the server under 连接器 → 自定义连接器 (steps).

Cursor, Gemini CLI and other agentsCopy Anchor Link

The open npx skills installer works across most coding agents:

npx skills add sellersheetai/sellersheet-skills            # the whole bundle
npx skills add sellersheetai/sellersheet-skills --list     # preview first
npx skills add sellersheetai/sellersheet-skills -a codex   # one specific agent
npx skills add sellersheetai/sellersheet-skills -g         # user level instead of per project

No Node.js? Use the install script with --target <agent>, or clone the repository and copy its skills/ folder into your agent's skills directory. Skills installed this way don't connect the server — add it as in Connect an AI client.

The skills always install together: they share one small companion skill with the common rules (how to start a session, store refs, how to read a result), so a partial install is not supported.

Keep them up to dateCopy Anchor Link

• Claude Code / CodeBuddy: run /plugin, open Marketplaces, select sellersheet-marketplace and choose Enable auto-update — third-party marketplaces don't update on their own until you do. Or update on demand: /plugin marketplace update sellersheet-marketplace, then /plugin update sellersheet-skills.
• Claude (claude.ai and the desktop app): in Customize → Plugins, turn on Sync automatically for the marketplace, or select Check for updates to pull the latest now.
• Other agents: re-run the installer with --update (or --check to compare).

Check itCopy Anchor Link

Ask: "Show me my SellerSheet user context." Your agent calls get_user_context, which also tells it whether its skills are current.
