SoFi Connector (browser-based, for Muse)

SoFi exposes no personal investing API, and Plaid withholds cost basis on SoFi
holdings. This connector drives a live browser through SoFi's website to read
the Active Invest (self-directed brokerage) positions table — including
per-position average cost and cost basis.

Read-only. It never places trades, moves money, or changes settings.

How it works

1. Signs into sofi.com with a saved login from the Secure Vault
   (Cloudflare Turnstile checkbox + SMS/email OTP handled per the standing
   user permissions documented in SKILL.md).
2. Opens the Active Invest account's holdings page. The holdings table has no
   cost-basis column, so it opens each position's detail page and reads
   "Avg cost" from the "Your investments" section.
3. Returns a JSON array: ticker, qty, price, market_value, avg_cost, cost_basis, as_of plus cash rows.

Layout

• SKILL.md — the connector skill (workflow, auth, output contract).
• references/sofi-notes.md — live-probe notes on SoFi's login page, bot
  defenses, and layout quirks.

Built for Muse personal-agent use.
