## What it does

This skill handles Holoscan SDK Conda installation requests. Because SDK 5.0 has no Conda package, it stops the agent from creating an environment, installing Miniforge, or attempting an impossible solve. For later 5.x releases, it checks documented support and verified published packages before running any command.

Conda-forge packages for 4.x belong to a different release line and will not satisfy a 5.x request. When Conda is unavailable, the skill suggests alternatives while preserving your target language. It routes Python requests to `holoscan-install-wheel`, native C++ setups to `holoscan-install-debian`, and combined setups to `holoscan-install-container`. If goals remain unclear, `holoscan-setup` evaluates the environment.

Existing Conda installations remain intact during the check. This approach prevents hallucinated setup commands when official packages do not exist.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill holoscan-install-conda -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill holoscan-install-conda -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill holoscan-install-conda -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install NVIDIA/skills holoscan-install-conda
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill holoscan-install-conda -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/NVIDIA/skills --path skills/holoscan-install-conda
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add NVIDIA/skills --skill holoscan-install-conda -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/NVIDIA/skills/tree/HEAD/skills/holoscan-install-conda/SKILL.md

## When to use it
- verify Conda package availability for Holoscan SDK 5.x
- prevent failed Conda solves on SDK 5.0
- route to wheel, Debian, container, or source alternatives
- handle requests for older 4.x Conda releases correctly

## Example prompts
- Install Holoscan SDK 5.0 using Conda
- Set up Holoscan SDK 5.x in a Conda environment
- Check if Holoscan 4.x is available via Conda

# Holoscan 5.0 and Conda

This skill checks Conda availability for the requested Holoscan SDK 5.x release.
SDK 5.0 has no Conda package. For later releases, it follows the release's Conda
instructions when support is documented and matching packages are published.
Otherwise, it offers container, Debian, wheel, or source alternatives while
preserving the requested SDK version and C++ or Python goal.

Conda-forge Holoscan 4.x packages are a different release line and cannot satisfy
a 5.x installation request.

1. Establish the requested SDK release. For 5.0, explain that Conda installation
   is unavailable; do not install Miniforge, create an environment, or run a
   Holoscan Conda solve. For a later release, follow its documented Conda method
   only if that release explicitly supports it and the matching packages are
   published. If availability is unknown, report the uncertainty and offer the
   verified alternatives below rather than inventing an installation command.
2. When Conda is unavailable or unconfirmed, preserve the requested SDK version
   and the user's C++ or Python goal. Offer the matching skill when available,
   or use the release's installation guide directly:

   | Goal | Method |
   | --- | --- |
   | Ready-to-use C++ and Python environment | `holoscan-install-container` |
   | Native C++ headers and libraries | `holoscan-install-debian` |
   | Python environment | `holoscan-install-wheel` |
   | Early Access binaries unavailable, or SDK development | `holoscan-install-source` |

3. Confirm which alternative the user wants if they have not already chosen
   one. If the host or goal is unclear, use `holoscan-setup` to assess it.
4. If the user explicitly needs 4.x, consult that release's Conda instructions
   and report the version change before proceeding. Keep an existing Conda
   installation intact; its presence does not establish availability for the
   requested release.

Use the selected release notes and
[installation guide](https://docs.nvidia.com/holoscan/sdk-user-guide/setup/sdk-installation)
to establish current support. Do not treat a 4.x search result as 5.x support.
```
