# That desktop fly now sniffs out your AGENTS.md and CLAUDE.

[cursor](/en/tags/cursor/)/rules, .kiro/steering, plus roughly forty other marker files — and drifts toward the strongest "scent." An open editor window radiating an active project pulls it hardest; a closed folder icon or a buried directory emits a faint whiff.

I cloned the repo, ran `npm install && npm start`

, and within seconds the little insect was orbiting my VS Code window where a `CLAUDE.md`

sat open. Switched to a Finder pane showing a project root with `.cursor/rules`

— it banked left and hovered there. The heuristic is surprisingly readable: each detected marker adds weight, open windows multiply it, nested paths divide it. No ML model, just a deterministic scoring loop that runs every ~500 ms.

```
// package.json snippet — the marker list lives here
{
  "agentMarkers": [
    "AGENTS.md",
    "CLAUDE.md",
    ".cursor/rules",
    ".kiro/steering",
    ".github/copilot-instructions.md",
    "prompt.md",
    "system-prompt.md",
    ".windsurf/rules",
    ".continue/config.json"
    // … 30 more
  ]
}
```

The fork lives at `github.com/<forker>/desktop-fly-vibecode`

(search the name, it's the only one with "vibecode" in the description). Install is the usual Electron dance — `npm run build`

spits a signed macOS .dmg and a Windows .exe. Linux users get an AppImage. No auto-updater yet, so pin the release you like.

Caveats: it polls the accessibility tree, so macOS will nag for Screen Recording permission on first launch. On Wayland the window-title sniffing is hit-or-miss; X11 works fine. CPU sits around 0.3 % idle on an M2, spikes to 1.2 % when you have a dozen projects open — negligible.

Why bother? Purely ambient awareness. I keep it running on a second monitor; when the fly settles on a window I know that project still has its agent context wired up. If it wanders off to the dock, something’s stale — maybe the `.cursor/rules`

got deleted or the symlink broke. Stupid? Yes. Useful? Weirdly, for the five minutes a day I glance over and confirm the scent trail is still hot.

Worth the five-minute build if you already live inside Cursor, [Claude Code](/en/tags/claude%20code/), or Windsurf and want a passive dashboard that doesn't demand a browser tab.
