ツール定義とプロトコルへの準拠に関する自動分析に基づいています。
コンテキストコスト
~1,428トークン数（ツール定義）
~5.0 KB一般的なレスポンスサイズ
注意への影響は中程度（128k コンテキストの 1.12%）
これは、サーバーのツールがモデルのコンテキストに読み込まれるたびに消費されるおおよそのトークン数です。数が多いほど、ほかのタスクに使える注意が減ります。

🟢preflight(authority, action, context)
Validate whether a structured authority envelope contains enough explicit constraints for ScopeProof to evaluate one action. Free. Returns no substantive authorization verdict and accepts no credentials, raw prompts, arbitrary request bodies, or secrets.

}🟢check_action(authority, action, context)
Determine whether one proposed action is within explicitly supplied authority. $0.01 stablecoin machine payment. Returns within_scope, outside_scope, or review_required plus deterministic reason codes, policy/action digests, and a tamper-evident receipt. This is scope enforcement against supplied authority, not identity verification, legal authorization, or a safety guarantee.
