In plain words
What is it for?
Use it to surface permission prompts, question dialogs, agent input requests, and optionally idle sessions on supported desktop environments.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fp-yoohoo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

fp-yoohoo — the terminal comes to you

fp-yoohoo is the only plugin in the plaza that changes nothing about how you think or write. It injects no prior, reads no transcript, and tags no claims. It is pure mechanism, and it does one thing. When Claude Code stops to ask the user something, the terminal window comes to the front, so a waiting session cannot be missed and the user never has to remember to check back.

You have no behavior to follow here. If this skill loaded, the user is asking about the plugin, not asking you to act differently. Answer from the reference below and get out of the way.

What sets it off

fp-yoohoo subscribes to the Notification hook, filtered by notification type.

Type Meaning On by default
permission_prompt a tool call needs approval yes
elicitation_dialog a question or plan dialog is open yes
agent_needs_input an agent is blocked on the user yes
idle_prompt the prompt has sat idle for 60 seconds no, opt in

Turn end (the Stop hook) is deliberately not wired up. It fires after every single reply, which would raise the window dozens of times an hour and teach the user to ignore it.

How the raise happens

The hook runs as a grandchild of the terminal emulator, so it walks the parent chain until it meets one (Konsole, kitty, Alacritty, WezTerm, Ghostty, foot, Windows Terminal and friends). That pid is what a window gets matched on.

Backends are tried in order, and the first one whose desktop is present wins:

  • KDE Plasma, Wayland or X11, through a temporary KWin script loaded over D-Bus. Wayland forbids a client from raising itself, so the compositor is asked to do it instead. No extra packages are needed.
  • Hyprland and sway, through hyprctl or swaymsg.
  • X11, through wmctrl or xdotool.
  • macOS, through System Events, fronting the app by its unix id.
  • Windows, through SetForegroundWindow, falling back to flashing the taskbar entry when the OS refuses a background focus change.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
