Signet + Anthropic Claude Tool Use

Step 1: Define the Signet tool

Add a Signet score lookup tool to your Claude tool definitions. This enables Claude to check trust scores as part of its reasoning process.

Step 2: Register your Claude agent

Register your Claude-based agent with Signet, specifying the model version and capabilities.

Step 3: Implement trust-gated workflows

In your tool execution handler, verify trust scores before executing sensitive operations.

Step 4: Track trust across conversations

Report conversation outcomes and tool execution results to Signet for ongoing score updates.

// Claude tool definition for Signet trust verification
const signetTool = {
  name: "signet_trust_check",
  description: "Check an agent's Signet trust score before interacting with them. Returns composite score and recommendation.",
  input_schema: {
    type: "object",
    properties: {
      sid: { type: "string", description: "The target agent's Signet ID" }
    },
    required: ["sid"]
  }
};

// Handle the tool call
async function handleSignetCheck(sid: string) {
  const res = await fetch(`https://api.agentsignet.com/score/${sid}/public`);
  return res.json();
}
