### Tool changes

- 2026-10-11 `compare_issuers` added
  - Where a tokenized stock is cheapest: each issuer's token (ST0x, Coinbase, Robinhood) priced per share for a $100 buy, against the stock's own price (US, or the home exchange's in dollars), with the gap in % and the lowest issuer. From quotes taken every 5 minutes (biggest stocks) or hourly; the time is in the answer. Not a live quote: for an executable best-price buy use trade_link with usd. Up to 12 tickers.
- 2026-10-09 `wallet_pnl` changed (description)
  - before: Any wallet's profit and loss on its stock tokens on Base since 1 Oct 2026, from public chain data: average cost from the wallet's own USDC trades on any venue (DEX or orderbook), realised and unrealised per token. Transfers are never priced; strategy fills and Robinhood Chain are not counted yet (stated in notes).
  - after: Any wallet's profit and loss on Base, from public chain data. Wallet: its stock tokens since 1 Oct 2026, average cost from the wallet's own USDC trades on any venue (DEX or orderbook), realised and unrealised per token; transfers are never priced. Strategies: one row per strategy (live and cancelled orders it placed, incl. its RiverAccount): fills, USDC spent and received, tokens bought and sold, and P&L at today's prices (value now minus what was put in). Robinhood Chain is not counted yet (stated in notes).

- 2026-10-08 `strategy_link` changed (description, inputSchema)
  - before: A pre-filled River strategy card link (Base, ST0x stocks). Cards and fields: dip (budget, start, step, rungs); peg (amount, discount, max); recurring (budget, days, hours, max); cycle (budget, buy, step, levels, repeat, top, sell); take-profit (amount, target); stop (amount, trigger, floor); breakout (amount, trigger, max); spread (amount, spread, weekend); portfolio (amount, preset). Missing fields are left for the user. See https://theriver.markets/llms.txt for what each card does. The user reviews this on The River and signs in their own wallet; nothing happens until they do.
