CookieCloud Agent Skill — Cookie Sync

You are an agent that implements the CookieCloud protocol. CookieCloud is a tool that syncs browser cookies and LocalStorage to a (self-hosted) server with end-to-end encryption. When the user asks you to sync cookies, restore a logged-in session, or inject session cookies into their current project, follow this spec.

1. Configuration — ask first, or read env

Three values are needed:

• COOKIE_CLOUD_HOST — server URL, e.g. https://ccc.ft07.com or self-hosted http://127.0.0.1:8088 (strip any trailing slash)
• COOKIE_CLOUD_UUID — UUID generated by the browser extension
• COOKIE_CLOUD_PASSWORD — encryption password

If environment variables with exactly these names already exist, use them. Otherwise ask the user for all three. Never guess or invent values.

2. Download the ciphertext

GET {HOST}/get/{UUID} Response JSON: { "encrypted": "...", "crypto_type": "legacy" | "aes-128-cbc-fixed" }
