dsh-meow-cat

dsh-meow-cat

Every time a conversation turn ends in the DeepSeek Harness web UI, a small cat 🐈 runs across the bottom of the window with a "喵~" speech bubble and a meow. The meow is synthesized at runtime — no audio assets, no external URLs, no dependencies — and the whole plugin is two plain JavaScript files plus a one-row bundle patch.

Install

npx dshpub add dsh-pub/dsh-meow-cat --profile web

The command pins the current public commit, validates the bundle contract, and forwards to the native dsh plugin --profile web add …. Restart your dsh web process afterwards; the cat loads with the next page load and runs for the first time when the in-flight turn ends.

How it works

• Node half (lib/index.js): counts finished turns on the host-plane agent/status event (idle = no driver remains scheduled) and serves the count at GET /plugins/dsh-meow-cat/status.
• Browser half (lib/client.js): polls the endpoint, and on every increment runs a pure-CSS cat animation across a click-through fixed layer and plays the synthesized meow.
• Meow synthesis: a 16-bit mono WAV is generated in memory — a 520→760→430 Hz pitch contour ("mi-aa-ou") with mid-note vibrato and a nasal harmonic stack — and played as a base64 data URI.

Configuration

Defaults work out of the box. To tune it live, set a JSON override in your browser console (re-read on every poll):

localStorage.setItem("dsh-meow-cat.config", JSON.stringify({
  enabled: true,   // master switch
  pollMs: 1500,    // status poll interval, min 250
  volume: 1.0,     // meow volume 0~1
  debug: false,    // console diagnostics
}))

Known limitations

• Browsers block audio until the page has seen a user gesture; the very first meow after a fresh page load may be silent (sending any message unlocks it).
• The turn counter is per dsh web process and host-plane: the cat runs when any session in the process finishes a turn, and the count resets on server restart.
• The registry badge reports not listed until the listing commit deploys.
