From 30d44e07fa1a2fdd12524bd263d2aebacbd77922 Mon Sep 17 00:00:00 2001 From: Cody De Arkland Date: Wed, 1 Oct 2025 14:09:05 -0700 Subject: [PATCH 01/32] feat(node): Add Claude Code Agent SDK instrumentation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds Sentry tracing instrumentation for the @anthropic-ai/claude-agent-sdk following OpenTelemetry Semantic Conventions for Generative AI. Key features: - Captures agent invocation, LLM chat, and tool execution spans - Records token usage, model info, and session tracking - Supports input/output recording based on sendDefaultPii setting - Provides createInstrumentedClaudeQuery() helper for clean DX Due to ESM-only module constraints, this integration uses a helper function pattern instead of automatic OpenTelemetry instrumentation hooks. Usage: ```typescript import { createInstrumentedClaudeQuery } from '@sentry/node'; const query = createInstrumentedClaudeQuery(); ``` 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- packages/node/src/index.ts | 2 + .../tracing/claude-code/helpers.ts | 114 ++++++ .../integrations/tracing/claude-code/index.ts | 130 +++++++ .../tracing/claude-code/instrumentation.ts | 368 ++++++++++++++++++ .../node/src/integrations/tracing/index.ts | 3 + 5 files changed, 617 insertions(+) create mode 100644 packages/node/src/integrations/tracing/claude-code/helpers.ts create mode 100644 packages/node/src/integrations/tracing/claude-code/index.ts create mode 100644 packages/node/src/integrations/tracing/claude-code/instrumentation.ts diff --git a/packages/node/src/index.ts b/packages/node/src/index.ts index 84fdf97539bc..3bade178f809 100644 --- a/packages/node/src/index.ts +++ b/packages/node/src/index.ts @@ -26,6 +26,8 @@ export { amqplibIntegration } from './integrations/tracing/amqplib'; export { vercelAIIntegration } from './integrations/tracing/vercelai'; export { openAIIntegration } from './integrations/tracing/openai'; export { anthropicAIIntegration } from './integrations/tracing/anthropic-ai'; +export { claudeCodeIntegration, patchClaudeCodeQuery } from './integrations/tracing/claude-code'; +export { createInstrumentedClaudeQuery } from './integrations/tracing/claude-code/helpers'; export { googleGenAIIntegration } from './integrations/tracing/google-genai'; export { langChainIntegration } from './integrations/tracing/langchain'; export { langGraphIntegration } from './integrations/tracing/langgraph'; diff --git a/packages/node/src/integrations/tracing/claude-code/helpers.ts b/packages/node/src/integrations/tracing/claude-code/helpers.ts new file mode 100644 index 000000000000..ba6b2bbc1323 --- /dev/null +++ b/packages/node/src/integrations/tracing/claude-code/helpers.ts @@ -0,0 +1,114 @@ +import { getClient } from '@sentry/core'; +import { patchClaudeCodeQuery } from './instrumentation'; +import type { ClaudeCodeOptions } from './index'; + +const CLAUDE_CODE_INTEGRATION_NAME = 'ClaudeCode'; + +// Global singleton - only patch once per application instance +let _globalPatchedQuery: ((...args: unknown[]) => AsyncGenerator) | null = null; +let _initPromise: Promise | null = null; + +/** + * Lazily loads and patches the Claude Code SDK. + * Ensures only one patched instance exists globally. + */ +async function ensurePatchedQuery(): Promise { + if (_globalPatchedQuery) { + return; + } + + if (_initPromise) { + return _initPromise; + } + + _initPromise = (async () => { + try { + // Use webpackIgnore to prevent webpack from trying to resolve this at build time + // The import resolves at runtime from the user's node_modules + const sdkPath = '@anthropic-ai/claude-agent-sdk'; + const claudeSDK = await import(/* webpackIgnore: true */ sdkPath); + + if (!claudeSDK || typeof claudeSDK.query !== 'function') { + throw new Error( + `Failed to find 'query' function in @anthropic-ai/claude-agent-sdk.\n` + + `Make sure you have version >=0.1.0 installed.`, + ); + } + + const client = getClient(); + const integration = client?.getIntegrationByName(CLAUDE_CODE_INTEGRATION_NAME); + const options = integration?.options || {}; + + _globalPatchedQuery = patchClaudeCodeQuery(claudeSDK.query, options); + } catch (error) { + const errorMessage = + error instanceof Error + ? error.message + : 'Unknown error occurred while loading @anthropic-ai/claude-agent-sdk'; + + throw new Error( + `Failed to instrument Claude Code SDK:\n${errorMessage}\n\n` + + `Make sure @anthropic-ai/claude-agent-sdk is installed:\n` + + ` npm install @anthropic-ai/claude-agent-sdk\n` + + ` # or\n` + + ` yarn add @anthropic-ai/claude-agent-sdk`, + ); + } + })(); + + return _initPromise; +} + +/** + * Creates a Sentry-instrumented query function for the Claude Code SDK. + * + * This is a convenience helper that reduces boilerplate to a single line. + * The SDK is lazily loaded on first query call, and the patched version is cached globally. + * + * **Important**: This helper is NOT automatic.
