How to Install a Skill Bundle

A complete guide to installing a skill bundle: the CLI command (npx skills-il add-bundle), the ZIP-of-ZIPs download, and uploading to Claude Desktop, Claude.ai, ChatGPT, and Manus. Includes what a bundle is and how it differs from a single skill.

What Is a Bundle?

A bundle is a hand-picked collection of multiple skills grouped together to cover a complete workflow rather than a single task. For example, the freelancer-accountant bundle includes a skill for invoicing (Green Invoice), a skill for VAT reporting, a skill for self-employed status, and a skill for receipts, so freelancers get everything they need for accounting in one install instead of hunting for each skill separately.

The difference between a bundle and a single skill:

  • Single skill = one unit. Install it and get one specific capability.
  • Bundle = 3 to 7 skills installed together in one action. They were curated for a specific persona (freelancer, lawyer, Israeli startup), verified to complement each other, and share a landing page that tells the story.

What You Need

Just two things:

  1. An AI tool like Claude Code, Cursor, GitHub Copilot, Windsurf, Claude.ai, Claude Desktop, ChatGPT, or Manus
  2. A browser to visit the bundles directory

Option 1: Install via CLI (easiest if you have a coding agent)

If you have a coding agent that uses the terminal (Claude Code, Cursor, GitHub Copilot, Windsurf, OpenCode, Codex, Antigravity, or Gemini CLI), this is the easiest path. One line installs every skill in the bundle:

npx skills-il add-bundle <bundle-slug>

For example:

npx skills-il add-bundle freelancer-accountant

The CLI auto-detects which AI agents you have installed in the project (.claude/, .cursor/, .windsurf/, etc.) and installs every skill into each one. No need to run the command per skill.

Tip: the bundle page has a "Copy" button that copies the exact command to your clipboard. Just paste it into your terminal.

To list available bundles:

npx skills-il bundles

Option 2: ZIP Download (for platforms without a terminal)

Claude.ai, Claude Desktop, ChatGPT, and Manus don't give you terminal access. For these we prepared a special bundle download.

Important: this is a ZIP that contains other ZIPs inside

Unlike a single skill where you download one ZIP file and upload it to the platform, a bundle downloads as a ZIP-of-ZIPs: one outer file that contains a separate ZIP inside it for every skill in the bundle. The reason: Claude.ai, Claude Desktop, and ChatGPT expect one ZIP per skill. They can't unpack a whole bundle as a single unit, so each skill needs to be uploaded separately.

The flow is always the same:

  1. Click "Download ZIP" on the bundle page.
  2. Unzip the outer file (<bundle-slug>.zip) on your computer (right-click > "Open" / "Extract").
  3. Inside the extracted folder you'll see several inner ZIP files, one for each skill in the bundle (for example: green-invoice.zip, tax-vat-reporting.zip, etc.).
  4. Each of those inner ZIPs is a complete skill ready to upload.

Now the upload to your specific platform:

Claude.ai (Web)

  1. Go to claude.ai/settings/capabilities and click "Upload skill".
  2. For each inner ZIP: select it and upload. Repeat for every skill in the bundle (for example: 5 skills = 5 separate uploads).
  3. When done, open a new conversation. The skills will be detected automatically when the conversation is relevant.

Claude Desktop

  1. Open the app and click your name > Settings > Capabilities.
  2. Click "Upload skill" and upload the first inner ZIP.
  3. Repeat step 2 for every inner ZIP from the extracted folder.
  4. Close settings. Open a new conversation.

ChatGPT (Business / Enterprise / Edu / Healthcare)

Requires a ChatGPT Business, Enterprise, Edu, or Healthcare subscription. Personal plans (Plus / Free) don't currently support uploading skills.

  1. Go to your Workspace settings > Skills.
  2. Click "Add skill" and upload the first inner ZIP.
  3. Repeat step 2 for every inner ZIP in the bundle.
  4. Open a new conversation and trigger the relevant skill.

Manus

  1. Open Manus at manus.im and go to the Skills tab in the side menu.
  2. Click + Add > Upload a Skill, and upload the first inner ZIP.
  3. Repeat step 2 for every inner ZIP in the bundle.
  4. Open a new conversation. Type / to see the installed skills.

On ChatGPT, Claude.ai, and Claude Desktop each skill is uploaded separately. If you miss one of the inner ZIPs, some bundle capabilities won't be available. After uploading, double-check the skills list to confirm every skill appears.

How Do I Use a Bundle After Installing?

This is the magic of a bundle. You don't have to manually invoke each skill. Just start working with the AI normally, and it will pick the right skill for each task:

  • "Create an invoice for ILS 1,500 for client X" → the agent uses the Green Invoice skill.
  • "When is the next VAT reporting deadline?" → the agent uses the VAT reporting skill.
  • "Explain the difference between osek patur and osek murshe" → the agent uses the relevant skill.

Want to see the bundle in action before installing? Each bundle page has a "Talk to the skills" button that opens a chat with every skill in the bundle pre-loaded, no install required.

Frequently Asked Questions

Why a ZIP inside a ZIP and not a single file?

Because Claude.ai, Claude Desktop, and ChatGPT expect one ZIP per skill. They don't currently support a "bundle" format. We do the bundling on our side so you download once, then upload each skill the way the platform expects it.

Why not just install the skills one at a time instead of a bundle?

You can, but a bundle gives you two things: (1) we already curated which skills complement each other for a complete workflow, and (2) one command installs everything at once instead of running npx skills-il add five times. Also, if we add a new skill to the bundle later, you can re-run add-bundle and pick it up automatically.

Does a bundle take more space?

Not meaningfully. Each skill is a small folder with one or two Markdown files. Even a 7-skill bundle adds up to less than a megabyte.

Which bundles are available?

As of today there are 10 bundles: freelancer-accountant, israeli-tax-season, small-business-starter, israeli-dev-toolkit, government-navigator, legal-compliance, marketing-il, hebrew-first, health-navigator, real-estate-il. The up-to-date list lives on the bundles page.

A new version came out for a skill inside the bundle. What do I do?

Via the CLI: re-run npx skills-il add-bundle <bundle-slug> and it will overwrite the existing skills with the new version. On platforms where you upload ZIPs, re-download the outer ZIP, extract it, and re-upload the inner ZIPs that changed.
