- 2026-10-05 `connect_my_account` changed (description)
  - before: Account status: whether this session is connected to a 包租公 · YieldLord account, which tier it is on, and how many credits are left. Call this when the user asks "am I connected" or "how many credits do I have left", and when they ask about THEIR OWN positions, portfolio, morning brief or realized history — anonymous access cannot see those, and this explains what connecting unlocks and gives the link. Called with no arguments it returns text and a URL only. Call it again with start_authorization=true once the user has an account, to begin the OAuth flow — or, if you can't receive a browser redirect, with start_link=true (a link the user approves, then pickup=<pickup> gives you the token; nothing to copy back). A connected free account can also start its free Gold trial here (start_trial=true — always a two-step confirm with the user) or get the link to buy Gold. Call it again right after the user finishes signing in: for a connected account the reply lists every tool the connection unlocked (the tool list you fetched before sign-in only has the public ones — re-list tools after connecting).
  - after: Account status: whether this session is connected to a 包租公 · YieldLord account, which tier it is on, how many credits are left, and for Gold whether it is a trial or paid and when it ends.

## Tools (4)

- `connect_my_account`: Account status: whether this session is connected to a 包租公 · YieldLord account, which tier it is on, how many credits are left, and for Gold whether it is a trial or paid and when it ends. Call this when the user asks "am I connected" or "how many credits do I have left", and when they ask about THEIR OWN positions, portfolio, morning brief or realized history — anonymous access cannot see those, and this explains what connecting unlocks and gives the link. Called with no arguments it returns text and a URL only. Call it again with start_authorization=true once the user has an account, to begin the OAuth flow — or, if you can't receive a browser redirect, with start_link=true (a link the user approves, then pickup=<pickup> gives you the token; nothing to copy back). A connected free account can also start its free Gold trial here (start_trial=true — always a two-step confirm with the user) or get the link to buy Gold. Call it again right after the user finishes signing in: for a connected account the reply lists every tool the connection unlocked (the tool list you fetched before sign-in only has the public ones — re-list tools after connecting).
- `explain_option`: Explain ONE specific option contract the user named — ticker + put/call + strike + expiry. Unlike explain_score and compare_candidates, which can only explain contracts the engine already picked, this prices and scores the exact contract you ask about, including strikes the screener would never surface (deep in the money, far out of the money). Returns the live quote, Greeks, premium and collateral per contract, annualized yield, the chance it expires worthless (the SELLER's side), and the RENT score. If we cannot price it (no open interest, no bid, strike does not exist) it says so and why, rather than substituting a different contract. Output is analysis, not a recommendation to trade.
- `find_recommendations`: Find RENT-ranked option income candidates (candidates only, not advice) for a ticker. Set defined_risk=true for CREDIT SPREADS (bull put / bear call) instead of single-leg naked selling; omit it and we default to whatever this user actually trades. Output is analysis, not a recommendation to trade.
- `get_market_climate`: Current rent climate (market regime + VIX/IV env + macro proximity → seller-friendliness read). Output is analysis, not a recommendation to trade.
