BLACK_WALL — Pre-action risk gate for AI agents

Created By

BlueTier Operationsa month ago

A single `forecast` tool your agent calls before any irreversible action (send money, run SQL, delete data, post content). Returns a risk score (0–100), a reversibility class, named red flags from 28 failure modes, and a gate: proceed / confirm / human-required.

Overview

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.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
