Anthropic Observability

Overview

Every messages.create call should be instrumented. Track tokens, latency, cost, model, and errors.

Logging Wrapper

import Anthropic from '@claude-ai/sdk';

const client = new Anthropic();

async function trackedCreate(params: Anthropic.MessageCreateParams) {
  const start = performance.now();
  try {
    const message = await client.messages.create(params);
    const durationMs = Math.round(performance.now() - start);

    const log = {
      timestamp: new Date().toISOString(),
      model: message.model,
      input_tokens: message.usage.input_tokens,
      output_tokens: message.usage.output_tokens,
      cache_read_tokens: message.usage.cache_read_input_tokens || 0,
      duration_ms: durationMs,
      stop_reason: message.stop_reason,
      estimated_cost: (message., message.),
    };
    .(, .(log));

     message;
  }  (err) {
     durationMs = .(performance.() - start);
    .(, .({
      :  ().(),
      : params.,
      : err  . ? err.?. : ,
      : err  . ? err. : ,
      : err  . ? err.?.[] : ,
      : durationMs,
    }));
     err;
  }
}
