Offload a deep, self-contained job — code review, planning, hard reasoning, an architecture second opinion — to your logged-in ChatGPT Pro subscription in the BACKGROUND, keep working locally, and get woken with the full answer to verify. A multi-round thread, not a one-shot. Use ONLY when the inputs are public GitHub links (public repo / PR / tree / blob). NEVER send secrets, private code, .env, tokens, or customer data. Drives a dedicated Chrome tab you logged into by hand; no API key, no per-token bill.

Analyze a US stock with the "5+2 method" — a systematic fundamental framework popularized by the Chinese-language US-equity channel 美投君 (MeiTouJun). 5+2 = 7 steps: the first 5 are objective (① industry ② business model ③ management ④ financials ⑤ valuation), the last 2 are subjective (⑥ why-to-buy / investment logic, ⑦ why-not / risks). Output is a research brief — "full understanding + is it fairly valued + bull case vs bear case." Use when the user asks to "analyze TICKER with the 5+2 method" or types `/meitou TICKER`. Hard numbers come from the bundled data adapter; qualitative steps (industry/moat/management) come from web research.
