Tools & Capabilities Breakdown

forecast

Call this BEFORE taking ANY irreversible or high-stakes action — sending an email, making a payment, running SQL, deleting files or data, posting public content, calling an external API that changes state. It returns a risk score (0–100), a recommendation (GO / CAUTION / STOP), and named red flags. If the recommendation is STOP, do not take the action — surface the flags to the user instead. If CAUTION, confirm with the user first.

observe

Call this AFTER an action runs (or after deciding NOT to run it because BLACK_WALL returned STOP/HUMAN_REQUIRED) to report what actually happened. Closes the loop with the earlier forecast — BLACK_WALL compares your observation to the prediction to track accuracy and improve future forecasts. FREE — no tokens charged. Always call this if you have a forecast_id from a recent `forecast` call.
