## What it does

The skill looks for the canary file `tooluniverse-drug-research/SKILL.md` across the usual skill directories: `.cursor`, `.agents`, `.windsurf`, `.gemini`, `.claude`, `.opencode`, `.trae`, `.skills`. A returned path means the skills are already there and the run stops. A `NOT_INSTALLED` result sends it into the install branch.

Installation clones `mims-harvard/ToolUniverse` with `git clone --depth 1 --filter=blob:none --sparse` into a temp folder, then narrows the checkout with `git sparse-checkout set skills`, so only the `skills` folder comes down. The contents are copied into your client's directory — `.claude/skills/` for Claude, `.cursor/skills/` for Cursor — and the temp folder is removed. The client is picked from whichever config directory exists; if none matches, the skill asks which one you use before copying anything.

You need `git` on the machine and network access to GitHub, since the clone is remote. The skill ships with `disable-model-invocation: true`, so it will not call itself mid-conversation — you trigger it by hand. Worth checking how your client treats such skills before you count on it firing on its own.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-install-skills -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/tooluniverse-install-skills/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/tooluniverse-install-skills/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-install-skills -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/tooluniverse-install-skills/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-install-skills -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/tooluniverse-install-skills/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install mims-harvard/ToolUniverse tooluniverse-install-skills
```

2. **Manually: put the files in place**
- File: `.github/skills/tooluniverse-install-skills/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-install-skills -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/mims-harvard/ToolUniverse --path skills/tooluniverse-install-skills
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/tooluniverse-install-skills/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add mims-harvard/ToolUniverse --skill tooluniverse-install-skills -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/mims-harvard/ToolUniverse/tree/HEAD/skills/tooluniverse-install-skills/SKILL.md

## When to use it
- locate where your client keeps skills instead of guessing paths
- reinstall the ToolUniverse research skills after moving to another client
- verify the skills actually landed in the right directory
- pull only the `skills` folder from the repo instead of the whole tree
- sort out which client is in use when several config directories exist

## Example prompts
- check whether the ToolUniverse skills are installed and add the missing ones
- the ToolUniverse skills aren't loading — figure it out and install them
- I moved from Cursor to Claude, bring the ToolUniverse skills over

name: tooluniverse-install-skills
description: Detect and auto-install missing ToolUniverse research skills. Checks common Claude Code/Cursor/Codex skill directories for the canary file, and installs any missing skills if none found. Use when the plugin's research skills aren't loading, when migrating between clients, or when verifying a skill installation.

# ToolUniverse Install Skills

Checks whether the ToolUniverse specialized skills are installed and installs them automatically if not.

## Detection

Use the Shell tool to check for the canary file across all common client locations:

```bash
ls .cursor/skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || ls .agents/skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || ls .windsurf/skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || ls .gemini/skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || ls .claude/skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || ls .opencode/skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || ls .trae/skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || ls .skills/tooluniverse-drug-research/SKILL.md 2>/dev/null \
  || echo "NOT_INSTALLED"
```

- **Output is a file path** → skills already installed, stop here.
- **Output is `NOT_INSTALLED`** → proceed to installation.

## Installation

```bash
# 1. Download skills from GitHub (shallow, sparse — only skills/ folder)
git clone --depth 1 --filter=blob:none --sparse \
  https://github.com/mims-harvard/ToolUniverse.git /tmp/tu-skills
cd /tmp/tu-skills && git sparse-checkout set skills

# 2. Copy to the correct directory for the detected client:
mkdir -p .cursor/skills  && cp -r /tmp/tu-skills/skills/* .cursor/skills/   # Cursor
# mkdir -p .agents/skills  && cp -r /tmp/tu-skills/skills/* .agents/skills/  # Codex/OpenAI
# mkdir -p .windsurf/skills && cp -r /tmp/tu-skills/skills/* .windsurf/skills/ # Windsurf
# mkdir -p .gemini/skills  && cp -r /tmp/tu-skills/skills/* .gemini/skills/  # Gemini CLI
# mkdir -p .claude/skills  && cp -r /tmp/tu-skills/skills/* .claude/skills/  # Claude Code
# mkdir -p .opencode/skills && cp -r /tmp/tu-skills/skills/* .opencode/skills/ # OpenCode
