## Signals and evidence

- NEW · 2d OLD WHEN SEEN

## TESIGN TAKE

On Windows and Linux, where there is no notch, it appears along the top edge of the screen.

## WHY IT MATTERS

It is easy to miss a permission prompt while your AI agent works in another window. Coucou shows what each session reads, edits and runs, and puts Allow and Deny buttons up top when Claude Code asks.

## BUILD FROM THIS

- Live view of Claude Code, Gemini CLI, Antigravity and other agent sessions, a jump to the right terminal window (macOS), and chat with Claude from the notch. It says there is no telemetry or account and that keys live in the OS keychain.

## WHO IT'S FOR

- Developers who run several AI coding agents at once.

## START IN 5 MINUTES

```
# Download the macOS build from the Install section of the repository (macOS 15 or later).
```

## CAVEATS

- The Windows installer is temporarily unavailable because Microsoft Defender wrongly flags the unsigned file. Cursor and Codex pills are coming soon. A young project with about 2,500 stars.

## How to read this

- This file was produced by the same build, from the same data, as the tesign.com item page. The text is editorial; the numbers are stored observations.
- null in the JSON means not observed — never zero. The Markdown writes [unconfirmed] for it.
- Star total = the value last checked on GitHub (stars_checked_at) + increases observed via GH Archive since. The 24h · 7d · 30d gains are GH Archive hourly events summed to the reference time (as_of). No score of ours.
- A summary, not legal advice.
