Requires: @anthropic-ai/claude-agent-sdk v0.2.0+ as a peer dependency. Works with the query() function for one-shot and multi-turn interactions.

​
What Gets Tracked Automatically

Sessions

Created on init, completed on result — with agent name, user ID, and metadata.

Tool Calls

Every tool execution (Bash, Read, Write, etc.) with input, output, and tool use ID.

Tokens & Cost

Prompt tokens, completion tokens, total tokens, and estimated cost in USD.

Conversation Threading

Group related sessions with convoId — multi-turn conversations appear linked.

Errors

Failed tool calls, errored sessions, and generator exceptions — all recorded.

Duration

Wall-clock time from start to result, plus API-side duration when available.

​
Installation

npm install @sentrial/sdk @anthropic-ai/claude-agent-sdk

​
Quick Start

Wrap the query() function once, then use it exactly like normal. 
import { query } from '@anthropic-ai/claude-agent-sdk';
import { SentrialClient, wrapClaudeAgent } from '@sentrial/sdk';

// 1. Create a Sentrial client
const sentrial = new SentrialClient({
  apiKey: process.env.SENTRIAL_API_KEY,
});

// 2. Wrap query()
const trackedQuery = wrapClaudeAgent(query, {
  client: sentrial,
  defaultAgent: 'my-agent',
  userId: 'user-123',
});

// 3. Use normally — everything is tracked
for await (const message of trackedQuery({
  prompt: 'Fix the failing tests in src/auth.ts',
  options: {
    maxTurns: 10,
    permissionMode: 'bypassPermissions',
  },
})) {
  if (message.type === 'assistant') {
    // Handle assistant messages
  }
}
// Session auto-completed with tokens, cost, duration, and all tool calls

​
Configuration Options

const trackedQuery = wrapClaudeAgent(query, {
  client: sentrial,           // required — SentrialClient instance
  defaultAgent: 'my-agent',   // optional — agent name for grouping (default: 'claude-agent')
  userId: 'user-123',         // optional — ties sessions to your end users (default: 'anonymous')
  convoId: 'convo-abc',       // optional — group sessions into a conversation thread
  extraMetadata: {             // optional — merged into every session's metadata
    environment: 'production',
    version: '1.2.0',
  },
});
Fail-Safe by Default — If Sentrial is unreachable, all messages pass through unchanged. Your agent never breaks due to tracking failures.

​
Conversation Threading

Use convoId to group related sessions into a conversation. Each call to trackedQuery() creates a new session, but they appear linked in the dashboard. 
const convoId = `user-${userId}-${Date.now()}`;

const trackedQuery = wrapClaudeAgent(query, {
  client: sentrial,
  defaultAgent: 'code-assistant',
  userId,
  convoId,
});

// Session 1: Explore the codebase
for await (const msg of trackedQuery({
  prompt: 'List all API routes and their handlers',
})) { /* ... */ }

// Session 2: Follow-up (same convoId, linked in dashboard)
for await (const msg of trackedQuery({
  prompt: 'Add rate limiting to the /api/users endpoint',
})) { /* ... */ }

​
How Tool Tracking Works

The wrapper uses PostToolUse and PostToolUseFailure hooks to capture every tool execution. Hooks fire asynchronously and never block the agent. A session-ready gate ensures hooks wait for session creation before tracking. 
// No extra code needed — tool calls are tracked automatically
for await (const message of trackedQuery({
  prompt: 'Read package.json and tell me the project name',
  options: {
    allowedTools: ['Bash', 'Read', 'Glob'],
  },
})) {
  // Each tool call (Read, Bash, etc.) is recorded as an event
  // with input args, output, and execution metadata
}
In the dashboard, each tool call appears as an event under the session timeline.

​
Error Handling

If the agent errors or the generator throws, the session is automatically marked as failed with the error message. 
try {
  for await (const message of trackedQuery({
    prompt: 'Deploy to production',
  })) {
    // ...
  }
} catch (error) {
  // Session already marked as failed in Sentrial
  // with failure_reason = error.message
  console.error(error);
}

Full Production Example

import { query } from '@anthropic-ai/claude-agent-sdk';
import { SentrialClient, wrapClaudeAgent } from '@sentrial/sdk';

const sentrial = new SentrialClient({
  apiKey: process.env.SENTRIAL_API_KEY!,
});

async function runAgent(userPrompt: string, userId: string) {
  const convoId = `session-${userId}-${Date.now()}`;

  const trackedQuery = wrapClaudeAgent(query, {
    client: sentrial,
    defaultAgent: 'code-review-agent',
    userId,
    convoId,
    extraMetadata: {
      environment: process.env.NODE_ENV,
    },
  });

  let result = '';

  for await (const message of trackedQuery({
    prompt: userPrompt,
    options: {
      model: 'claude-sonnet-4-20250514',
      maxTurns: 15,
      permissionMode: 'bypassPermissions',
      allowedTools: ['Bash', 'Read', 'Write', 'Glob', 'Grep'],
    },
  })) {
    if (message.type === 'result') {
      result = message.result ?? '';
    }
  }

  return result;
}
