## Summary - Replace asyncio.create_task() with anyio task group for trio compatibility - Update client.py docstring example to use anyio.sleep - Add trio example demonstrating multi-turn conversation ## Details The SDK already uses anyio for most async operations, but one line was using asyncio.create_task() which broke trio compatibility. This PR fixes that by using anyio's task group API with proper lifecycle management. ### Changes: 1. **subprocess_cli.py**: Replace asyncio.create_task() with anyio task group, ensuring proper cleanup on disconnect 2. **client.py**: Update docstring example to use anyio.sleep instead of asyncio.sleep 3. **streaming_mode_trio.py**: Add new example showing how to use the SDK with trio ## Test plan - [x] All existing tests pass - [x] Manually tested with trio runtime (created test script that successfully runs multi-turn conversation) - [x] Linting and type checking pass 🤖 Generated with [Claude Code](https://claude.ai/code) Signed-off-by: Rushil Patel <[email protected]>

…ropics#103) ## Summary Fixes a critical deadlock issue that occurs when MCP servers produce verbose stderr output. The SDK would hang indefinitely when the stderr pipe buffer filled up. ## The Problem The deadlock occurred due to sequential reading of subprocess streams: 1. SDK reads stdout completely before reading stderr 2. When stderr pipe buffer fills (64KB on Linux, 16KB on macOS), subprocess blocks on write 3. Subprocess can't continue to stdout, parent waits for stdout → **DEADLOCK** 🔒 ## The Solution Redirect stderr to a temporary file instead of a pipe: - **No pipe buffer** = no possibility of deadlock - Temp file can grow as needed (no 64KB limit) - Still capture stderr for error reporting (last 100 lines) - Works consistently across all async backends ## Implementation Details - `stderr=tempfile.NamedTemporaryFile()` instead of `stderr=PIPE` - Use `deque(maxlen=100)` to keep only recent stderr lines in memory - Temp file is automatically cleaned up on disconnect - Add `[stderr truncated, showing last 100 lines]` message when buffer is full ## Testing - Verified no deadlock with 150+ lines of stderr output - Confirmed stderr is still captured for error reporting - All existing tests pass - Works with asyncio, trio, and other anyio backends ## Impact - Fixes consistent hangs in production with MCP servers - No functional regression - stderr handling is preserved - Simpler than concurrent reading alternatives - More robust than pipe-based solutions Fixes the issue reported in Slack where SDK would hang indefinitely when receiving messages from MCP servers with verbose logging. 🤖 Generated with [Claude Code](https://claude.ai/code) --------- Co-authored-by: Claude <[email protected]> Signed-off-by: Rushil Patel <[email protected]>

## Summary
Fixes an issue where `thinking` content blocks in Claude Code responses
were not being parsed, resulting in empty `AssistantMessage` content
arrays.
## Changes
- Added `ThinkingBlock` dataclass to handle thinking content with
`thinking` and `signature` fields
- Updated client parsing logic in `_internal/client.py` to recognize and
create `ThinkingBlock` instances
- Added comprehensive test coverage for thinking block functionality
## Before
```python
# Claude Code response with thinking block resulted in:
AssistantMessage(content=[]) # Empty content!
```
## After
```python
# Now correctly parses to:
AssistantMessage(content=[
ThinkingBlock(thinking="...", signature="...")
])
```
Fixes anthropics#27
