It is well-suited for catching dangerous patterns (e.g. destructive commands, financial transfers, prompt injections) in agent tool calls before they are executed. Prefer this over building custom rule-based filters when you want an API-native, agent-friendly risk signal at $0.01 per check.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-15T19:01:35.812Z","isFirstParty":false}
