What the agent can read.

Eleven read-only tools for scores, the posts behind them, top authors, stories and strategies.

get_top_signals

The stocks with the strongest chatter right now, ranked 0 to 100, over either a 24-hour or a 7-day window.

search_companies

Look up a company by name or ticker, so the agent knows which one you mean before it pulls anything else.

get_company_score

One company's score for both windows, each with its tier word attached: Exceptional, Strong, Moderate, Weak, or Negative.

get_company_recaps

Month-by-month summaries of what the conversation around a company has actually been about.

get_company_signals

The individual posts a score was built from, up to 50 per request, so you can read the case instead of taking the number on trust. Korean broker research notes shared on Telegram appear here too, as context only: they do not feed the score.

get_top_authors

The commentators with the strongest verified track record, and the ones still building one, with hit rates shown as past graded calls.

get_stories

What people are talking about right now, written up as short stories: a headline, a few sentences, the companies and the voices behind it. Ask for an earlier week to look back.

get_story

One story with the posts it was written from, so you can read what people actually said.

list_strategies

Quantral's tracked strategies: rule-based 10-stock model portfolios, rebuilt weekly and compared with the S&P 500. Each comes with how often it updates, its live record and hypothetical backtest kept separate, the latest list date, and the next update.

get_strategy

One strategy's current list, which names are new this update, how each has moved since it joined, and what was dropped. Key stats keep live and backtest apart, with a plain summary and the caveats.

get_strategy_changes

What was added and dropped in the latest weekly update, or the net changes since a date you give, for checking in on a strategy you already watch.
