Every session. One place.

The problem

You run Claude Code in one window and Codex in another. Three repos. Six tabs. Every one of them is burning context and quota right now. Nothing on your screen says which.

• Which one is alive. A terminal tab will not tell you which session just came back.
• Which one it is. You do not remember the generated title. You remember what you typed: ship the first build.
• How much is left. Context drains. Quota drains. You find out when you hit the wall.

You pay for every agent you run. What you cannot see is where each one stands.

What it does

It puts every session in the notch. One place. It stays sorted.

• Resting. The agent, your last line, how much window is left. No click.
• Open. Every session from today in one list, both tools side by side.
• Act. Resume drops you back into that session. Start new. Save memory.

Claude Code Codex

It reads the files these two already write to your disk. Nothing to connect, nothing to sign in to, nothing running alongside it.

The notch is a hole, not a screen. Draw in the middle 185pt and nothing shows. So the header sits in the two gaps beside it. The hardware wrote that layout, not us.

Where it stands

• The list is real. It reads the files both agents already write. On your machine. 24 hours back.
• Codex quota is real. Codex writes its rate limit into its own session rollout.
• Claude Code quota is blank. Same field, null in all 35 transcripts on this machine. The reader is written. It lights up the day Claude Code starts reporting one.

A made-up number fails once. After you have trusted it.

Install

Unzip it. Drag EchoIsland.app into Applications. Open it. No dock icon — the island is the app, and Quit sits under ◗ in the menu bar.

The first open gets stopped. This build is ad-hoc signed and not notarized yet, so macOS says it cannot verify the app is free of malware. That sentence means Apple has not looked. It does not mean Apple looked and found something.

1. Double-click once. That makes macOS log the block.
2. Open System Settings → Privacy & Security, scroll to Security, click Open Anyway.
3. Confirm once more. Double-click works from then on. You do this one time.

One command does the same thing:

xattr -dr com.apple.quarantine /Applications/EchoIsland.app

Notarization lands when the Developer ID does, and this whole section goes away. Checksum for this build: —
