What it does

Notification is an agent skill from mikeyobrien/rho. Show Linux desktop notifications with title, body, urgency, and icons. Use for alerts, reminders, or status updates.

Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with Linux. The repository describes itself as: An AI agent that stays running, remembers across sessions, and checks in on its own. macOS, Linux, Android. Built on Pi. The licence is MIT.

Example prompts

  • “/notification”

What it can do on your machine

Read from SKILL.md and the folder at commit 073a3ee. 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
    • dnf

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

  • Network

    No URLs in SKILL.md.

    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

Notification loads about 363 tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 47 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~363

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

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteRuns commands with sudoSKILL.md:13
    sudo apt install libnotify-bin
  • NoteRuns commands with sudoSKILL.md:16
    sudo pacman -S libnotify
  • NoteRuns commands with sudoSKILL.md:19
    sudo dnf install libnotify

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.

Desktop Notifications

Requires notify-send from the libnotify package.

Install

bash
# Debian/Ubuntu
sudo apt install libnotify-bin

# Arch
sudo pacman -S libnotify

# Fedora
sudo dnf install libnotify

Basic notification

bash
notify-send "Title" "Message body"

With urgency

bash
notify-send -u low "Info" "Low priority message"
notify-send -u normal "Update" "Normal priority"
notify-send -u critical "Alert" "Critical -- won't auto-dismiss"

With icon

bash
notify-send -i dialog-information "Info" "With info icon"
notify-send -i dialog-warning "Warning" "With warning icon"
notify-send -i dialog-error "Error" "With error icon"
notify-send -i /path/to/icon.png "Custom" "With custom icon"

With expiration (milliseconds)

bash
notify-send -t 5000 "Title" "Disappears after 5 seconds"
notify-send -t 0 "Title" "Persistent until dismissed"

With app name and category

bash
notify-send -a "MyApp" -c "transfer" "Download" "Complete"

Replaceable notification (update in place)

bash
notify-send -h int:transient:1 -r 12345 "Progress" "50%"
notify-send -h int:transient:1 -r 12345 "Progress" "100%"

On headless/SSH systems without a display server, notify-send will fail. Use wall or write to a log file instead.
