Install the Codex desktop companion “Gemini · Twinshine” for me.

Safety rules (follow every item):
1. Download only this immutable ZIP: https://raw.githubusercontent.com/FrankLeLe/AI-Pet-Agents/6bfce72ca689966918c3bb85c68007914a27f54c/public/downloads/gemini-twincrest-duck.zip
2. Verify SHA-256 exactly: 7ce452af8771f844f0caad8285573fc39ef172bf8af80776c34773f3735760e5
3. Resolve CODEX_HOME first; if it is not set, use ~/.codex. Only inspect or write CODEX_HOME/pets/gemini-twincrest-duck. Do not modify any other folder.
4. Before extracting, verify the ZIP has one top-level gemini-twincrest-duck/ folder containing only pet.json and spritesheet.webp.
5. If CODEX_HOME/pets/gemini-twincrest-duck already exists, stop and ask me before replacing anything. Never overwrite silently.
6. After installation, list the files you wrote and remind me to fully quit and reopen Codex Desktop.

Do not install executables, run scripts from the archive, or change my Codex configuration.
Command-line install (advanced)

The command stops if the target folder already exists and never overwrites silently. Confirm the ZIP is in Downloads before running it.

$petId = "gemini-twincrest-duck"
$codexRoot = if ($env:CODEX_HOME) { $env:CODEX_HOME } else { Join-Path $env:USERPROFILE ".codex" }
$petsRoot = Join-Path $codexRoot "pets"
$target = Join-Path $petsRoot $petId
$archive = Join-Path $env:USERPROFILE "Downloads\$petId.zip"

if (Test-Path -LiteralPath $target) { throw "$petId already exists. Stop and review it before replacing anything." }
New-Item -ItemType Directory -Force -Path $petsRoot | Out-Null
Expand-Archive -LiteralPath $archive -DestinationPath $petsRoot

Before running, confirm the ZIP is in your Downloads folder. Fully quit and reopen Codex Desktop after installation.
