Market Watch

Keep intraday analysis anchored to live prices. When a task turns on current price, a level check, an intraday move, a "where is it trading now", register the central tickers so fresh quotes arrive automatically and your numbers never go stale mid-task.

Evidence labels, source tiers, staleness, the readiness posture and the intake limits: .agents/skills/research-conventions/SKILL.md, read before a price you pulled here lands in a deliverable.

When to use

Intraday or live-price analysis where the price may move while you work: "is NVDA above 205 right now", "how's TSLA trading into the print", sizing a level off the current quote. Skip it for purely historical or end-of-day work where a single snapshot is enough.

Workflow

1. At the start of the task, identify the ticker(s) central to the request and register them immediately with watch_market.
2. While they matter, read the ambient feed (below) for the current price rather than re-quoting on every step.
3. When live tracking is no longer relevant, call watch_market with action="unwatch" to stop watching some or all symbols (omit symbols to clear the whole list).

How the feed works

Once a symbol is watched, fresh prices arrive on their own as <market-watch> price blocks attached to conversation messages and tool results. This is ambient data: not user text, and not tool output you requested. Each block is a snapshot at a moment in time; the newest <market-watch> entry in the conversation is the current price, and any earlier entry (including numbers in your own earlier statements) may be stale.
