Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

broker-auth: Bind Platform Accounts

Handles the "bind once, reuse" account authorization flow.

How It Works

User selects platform(s) to bind (Xianyu, Zhuanzhuan, eBay, Depop)
Script opens a Chromium browser to the platform's login page
User logs in manually (scan QR code, enter credentials)
Browser closes → cookies are persisted to ~/.broker/sessions/_session.json
Subsequent skills reuse the session transparently
Sessions auto-expire after 30 days; when expired, user is prompted to re-bind

Script

python3 -m broker_core.session_manager login 
    # Opens browser, captures cookies, saves session

python3 scripts/auth.py          # Wrapper for broker-auth flow

Important Notes

This is NOT web scraping. The user authorizes Claude to use their own account session for search and publish operations.
Cookie files are stored locally in ~/.broker/sessions/. Never shared.
No passwords are stored — only browser cookies.
The session is used exclusively for: searching listings, publishing items, checking listing status, and delisting.
