A Claude Code plugin is a folder of skills, agents, hooks, and slash commands that Claude installs per project. 28 plugins, 68 skills here.

/plugin marketplace add aiocean/claude-plugins
/plugin install <plugin-name>@aiocean-plugins

Skills load when their description matches your message, hooks fire on tool-call events, agents spawn on the Agent tool. Idle plugins cost nothing — browse plugins or read the guides.

aio-browser-cookie

Your browser already holds the session you need. This plugin extracts it.

When you need to make authenticated requests from Claude — scraping a page you're logged into, replaying an API call, feeding cookies to curl, yt-dlp, or wget — the usual path is tedious: open DevTools, copy cookies one by one, format them correctly, hope nothing expired. This plugin short-circuits that entirely. It reads the local cookie store of Chrome, Firefox, Safari, Brave, Arc, or a dozen other Chromium variants directly, then hands you the session in whatever format your tool expects.

The underlying library is rookiepy, which handles the platform-specific decryption (keychain on macOS, libsecret on Linux, DPAPI on Windows). You point it at a browser and a domain; it returns the live session.

Install

/plugin install aio-browser-cookie@aiocean-plugins

What the skill does

Extraction. Pull cookies for any domain from any supported browser and print them as JSON, a Cookie: header string, or Netscape format (the format curl, wget, and yt-dlp understand).

Request replay. Send an HTTP request with the extracted session injected automatically — useful for testing what an authenticated page returns without leaving Claude.

Doctor check. Verify that Python, rookiepy, and the available browser loaders are all present before attempting extraction.

Trigger phrases: "extract browser cookies", "reuse browser session", "export cookies", "chrome cookies", "firefox cookies", "netscape cookie jar", "authenticated request".

Quick example

# Save cookies for curl
BCOOKIE="${CLAUDE_PLUGIN_ROOT}/skills/aio-browser-cookie/scripts"

python3 "$BCOOKIE/rookie_tool.py" extract \
  --browser chrome \
  --domain example.com \
  --format netscape \
  --output /tmp/example.cookies

curl --cookie /tmp/example.cookies https://example.com/account

Requirements

• Python 3
• pip3 install -U rookiepy

On macOS, Safari may require Full Disk Access for the terminal. Chromium-based browsers may trigger a keychain prompt during decryption. Treat exported cookies as secrets — do not paste them into chat or commit them to version control.
