Holoscan Install Debian

What it does

When your agent uses it

• C++ installs on Ubuntu
• Pair with /holoscan-install-wheel for Python

Example prompts

• “/holoscan-install-debian”

Requirements

• Python 3

Workflow steps

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

1. 1Consult the Official Install Instructions
2. 2Prerequisites Check
3. 3Install
4. 4Verify
5. 5Give the User the Reusable Env Snippet

What it can do on your machine

Read from SKILL.md and the folder at commit 0e0d506. 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
  • python3
  • wget

  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:

  • docs.nvidia.com
  • developer.download.nvidia.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 Debian loads about 1.6k tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 493 words of instructions outside code blocks.

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

~38

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

~1.6k

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:82

  sudo dpkg -i cuda-keyring_1.1-1_all.deb && sudo apt-get update

• NoteRuns commands with sudoSKILL.md:84

  sudo apt-get install -y holoscan-cuda-12   # or holoscan-cuda-13

• NoteRuns commands with sudoSKILL.md:104

  #   sudo apt-get remove -y holoscan-cuda-13 && sudo apt-get install -y holoscan-cuda-12

• NoteRuns commands with sudoSKILL.md:109

  ls $HS/data/racerx 2>/dev/null || sudo $HS/examples/download_example_data

  ia-smi` CUDA Version and swap variants: `sudo apt-get remove -y holoscan-cuda-13 && sudo apt-get install -y holoscan-cud

• NoteRuns commands with sudoSKILL.md:141

  PATH=/opt/nvidia/holoscan/data`, or run `sudo /opt/nvidia/holoscan/examples/download_example_data` to fetch the `racerx`

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.
