…reference Add sampling strategy reference for gen_ai spans (JS + Python) covering: - Head-based sampling gotcha (root-only, children inherit) - tracesSampler patterns for both standalone agents and HTTP-child scenarios - Metrics/logs fallback for when 100% tracing isn't feasible - Cost comparison and troubleshooting Also adds: - Node.js ai-monitoring.md reference (was missing, Python/Next.js/NestJS had one) - Sampling check + user prompt to SKILL.md detection flow - Sampling cross-links to Python, Next.js, and NestJS references Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
- sampling.md: 242 → 78 lines. Removed 4 redundant code blocks (JS+Python metrics+logs shown separately), consolidated into one Python example + note that JS uses same pattern. Removed comparison table. - ai-monitoring.md (Node): 341 → 95 lines. Removed per-integration setup/wrapping/streaming sections, consolidated into single setup block with important notes callout. - Updated model names from gpt-4o to claude-sonnet-4-6.

Match Python SDK reference structure: add Integration Matrix with min library versions, Configuration Examples (auto + explicit + Vercel AI + browser), 4 manual instrumentation examples (chat, invoke_agent, execute_tool, handoff), Span Attribute Reference tables, Agent Workflow Hierarchy diagram, Streaming compatibility table. Updated model names. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Lists providers without auto-instrumentation in Node (Pydantic AI, OpenAI Agents SDK, HuggingFace Hub, MCP are Python-only; Cohere, Bedrock, Mistral, Groq need manual spans in both). Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Pydantic AI, OpenAI Agents SDK, HuggingFace Hub are Python libraries - not relevant to Node developers. MCP is a separate product with its own docs. Keep only providers a Node developer might actually encounter: Cohere, Bedrock, Mistral, Groq. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

We plan to remove this span type in the future so we should probably omit it here.

omg 🤦 they are really missing out on something like this https://community.openai.com/t/introducing-codex-plugin-for-claude-code/1378186 😂
- Remove gen_ai.handoff example (planned for deprecation per @obostjancic) - Fix openai("claude-sonnet-4-6") → openai("gpt-4.1") (wrong provider/model combo) - Remove handoff from span hierarchy diagram Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

gen_ai.chat is an internal SDK op. The docs document gen_ai.request for manual instrumentation. Fixed all code examples and span hierarchy. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
