Holoscan Install Source

What it does

When your agent uses it

• DevOps & Cloud work in your project

Example prompts

• “t meet the user”
• “/holoscan-install-source”

Requirements

• Docker

Workflow steps

6 steps, taken from the step headings in SKILL.md.

1. 1Consult the Official Install Instructions
2. 2Prerequisites

6. 6Point Applications at the Install Tree

What it can do on your machine

Read from SKILL.md and the folder at commit 67a13c0. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • apt-get
  • git
  • docker
  • curl
  • apt

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • nvidia.github.io
  • docs.nvidia.com
  • github.com

  Also links to:

  • docs.docker.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Holoscan Install Source loads about 1.5k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 531 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~37

When it runs · the whole SKILL.md, loaded when a task matches

~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

• NoteRuns commands with sudoSKILL.md:53

  a.github.io/libnvidia-container/gpgkey | sudo gpg --dearmor -o /usr/share/keyrings/nvidia-container-toolkit-keyring.gpg

• NoteRuns commands with sudoSKILL.md:56

  | sudo tee /etc/apt/sources.list.d/nvidia-container-toolkit.list

• NoteRuns commands with sudoSKILL.md:57

  sudo apt-get update && sudo apt-get install -y nvidia-container-toolkit

• NoteRuns commands with sudoSKILL.md:58

  sudo nvidia-ctk runtime configure --runtime=docker && sudo systemctl restart docker

• NoteRuns commands with sudoSKILL.md:60

  - If Docker buildx is missing: `sudo apt-get install docker-buildx-plugin`

• NoteRuns commands with sudoSKILL.md:93

  rch64` | Cross-compile for ARM64 (needs `sudo apt install qemu-user-static`) |

• NoteRuns commands with sudoSKILL.md:155

  | Docker buildx not found | `sudo apt-get install docker-buildx-plugin` |

• NoteRuns commands with sudoSKILL.md:156

  ify NVIDIA Container Toolkit and re-run `sudo nvidia-ctk runtime configure --runtime=docker` |

• NoteRuns commands with sudoSKILL.md:157

  compile fails (aarch64) | Install qemu: `sudo apt-get install qemu-user-static` |

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
