Blackwall

Before your agent deletes production data or wires $50k, it calls the forecast tool and gets back a risk score, reversibility class, and GO/CAUTION/STOP verdict in under 8 seconds. You wrap SQL statements, payments, file deletes, or emails in a single gate() call; if the verdict is STOP, the action never runs. Works in Claude Desktop, Cursor, Windsurf, or any Node agent via the library. Each forecast includes a cryptographic receipt you can verify offline. Start in observe mode to see what your agents almost did without blocking anything, then flip to enforce when you're ready. Free tier gives you about 100 forecasts per month.
