**BLACK_WALL** gives your agent a brake. It exposes a single tool, `forecast`, that the agent calls *before* any irreversible action — sending an email, making a payment, running SQL, deleting data, posting content. It returns: - a **risk score** (0–100) - a **reversibility class** + rollback cost (reversible / recoverable / irreversible) - a **gate**: proceed / confirm / human-required - named **red flags** from 28 documented failure modes (`SQL_NO_WHERE`, `INTENT_MISMATCH`
