BLACK_WALL
bluetier-operations
**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`, `CROSS_ENVIRONMENT`, `MASS_RECIPIENT`, `PROMPT_INJECTION_LIKELY`, …) A normal email clears in one call; a `DROP TABLE` on prod comes back **STOP / human-required** — before it runs. The agent can't talk itself into the bad action, because the verdict is a hard gate. **Setup:** paste your BLACK_WALL API key as the `apiKey` parameter. Get one free at https://blackwalltier.com (~100 forecasts/month, no card). A verdict takes ~4–8s. *A BLUETIER product.*
