What PreReason Does
Every financial API gives you numbers. Your agent then has to figure out what those numbers mean, how they relate to each other, whether they're high or low historically, and what direction they're moving. That interpretation step is where agents fail.
PreReason does the interpretation before your agent ever sees the data. One API call returns a complete market briefing with trend direction, confidence score, percentile ranking against the last 90 days, regime classification (risk-on, risk-off, transition), and a causal narrative connecting the signals.
Markdown by default. Not because JSON doesn't work, but because language is what LLMs are built to process. Raw numbers force your agent into its weakest mode. Structured language keeps it in its strongest.
