# Instrument Anthropic SDK

Canonical sample: [`samples/integrations/anthropic_traced.py`](https://github.com/layerlens/stratix-python/blob/main/samples/integrations/anthropic_traced.py) — captures multi-turn Claude conversations via manual trace upload.

For zero-code auto-instrumentation, the Anthropic provider adapter (`layerlens.instrument`) is the preferred path:

```bash
pip install 'layerlens[providers-anthropic]'
```

The adapter emits `model.invoke`, `cost.record`, and `tool.call` events for every Anthropic Messages API call (including streaming with single consolidated event on stream completion). Cache metadata included.
