🛡 Sentinel CaptureMac v2.54 · Windows v2.61

Sentinel Capture

Routes Claude (Chat · Cowork · Code) and Codex/ChatGPT through Sentinel on your own machine. One click turns it off.

🔑
Before you start — get your Sentinel key.
You need your Sentinel key (looks like sk-sentinel-…) — you'll paste it once during Setup.Codex/ChatGPT now has two options: Subscription capture (recommended, no API key — just your ChatGPT login) or API key routing (needs a real OpenAI API key). Claude works with your normal Claude login (OAuth) or an Anthropic API key.

🍎 macOS

⬇ Download for Mac
  1. Unzip it right in your Downloads folder — leave it there, don't move it.
  2. Run this first — open Terminal (Cmd+Space → "Terminal"), paste, press Return:
    xattr -dr com.apple.quarantine ~/Downloads/Sentinel*Capture* && chmod +x ~/Downloads/Sentinel*Capture*/*.command ~/Downloads/Sentinel*Capture*/Advanced/*.command

    macOS blocks files downloaded from the internet ("Apple could not verify… Move to Trash"). This clears that flag — without it, nothing opens. Right-click → Open is unreliable on current macOS, so don't rely on it.

  3. Double-click "1 - Setup (run once)" → pick environment, paste your key, then choose Claude, Codex, or Both and pick which surfaces to capture.
  4. Double-click "2 - Start capture" (Mac password) — it turns on capture and restarts your apps.
  5. Use Claude/ChatGPT normally — it's now captured.

Turn off anytime: STOP capture. Something stuck? PANIC RESET (in Advanced) undoes everything.

🪟 Windows

⬇ Download for Windows
  1. Needs Python 3 (python.org — tick "Add to PATH") only if you route a desktop app.
  2. Unzip it in Downloads, then open the extracted Sentinel Capture folder.
  3. Double-click "1 - Setup (run once)" → if SmartScreen warns, More info → Run anyway. Pick environment, paste your key, then choose Claude, Codex, or Both and pick which surfaces to capture. Setup enrolls diagnostics automatically and opens the installed folder when it finishes.
After Setup, stop using the Downloads copy.

Setup opens the correct installed folder automatically. To reopen it later, paste %USERPROFILE%\.sentinel-capture and press Enter. This works for every Windows username.

  1. From that installed folder, double-click "2 - START capture". Always run START, STOP, and diagnostics there—never from Downloads.
  2. Use Claude/ChatGPT normally — it's now captured.

Setup is the only launcher you run from Downloads. After Setup succeeds, the downloaded ZIP and extracted folder can be deleted.

If anything looks stuck, run STOP capture first — it always restores normal networking. If that's not enough, run PANIC RESET in the same folder — it undoes every change regardless of what state things are in. Your Sentinel key is used once to validate diagnostics enrollment and is never stored by the installer service.
