The bash install script (install.sh) explicitly rejects Windows. Use the
PowerShell installer (install.ps1) instead when running on Windows,
matching the approach used in test.yml.

Bundle platform-specific Claude Code CLI binaries directly in the Python
package, eliminating the need for separate CLI installation.
## Changes
### Build System
- Created `scripts/download_cli.py` to fetch CLI during build
- Created `scripts/build_wheel.py` for building platform-specific wheels
- Created `scripts/update_cli_version.py` to track bundled CLI version
- Updated `pyproject.toml` to properly bundle CLI without duplicate file
warnings
- Made twine check non-blocking (License-File warnings are false
positives)
### Runtime
- Modified `subprocess_cli.py` to check for bundled CLI first
- Added `_cli_version.py` to track which CLI version is bundled
- SDK automatically uses bundled CLI, falling back to system
installation if not found
- Users can still override with `cli_path` option
### Release Workflow
- Updated GitHub workflow to build separate wheels per platform (macOS,
Linux, Windows)
- Workflow now accepts two inputs:
- `version`: Package version to publish (e.g., `0.1.5`)
- `claude_code_version`: CLI version to bundle (e.g., `2.0.0` or
`latest`)
- Workflow builds platform-specific wheels with bundled CLI
- Creates release PR that updates:
- `pyproject.toml` version
- `src/claude_agent_sdk/_version.py`
- `src/claude_agent_sdk/_cli_version.py` with bundled CLI version
- `CHANGELOG.md` with auto-generated release notes
### Documentation
- Updated README to reflect bundled CLI (removed Node.js requirement)
- Added release workflow documentation
- Added local wheel building instructions
## Benefits
- **Zero external dependencies**: No need for Node.js or npm
- **Easier installation**: Single `pip install` gets everything
- **Version control**: Track exactly which CLI version is bundled
- **Flexible releases**: Can release new package versions with updated
CLI without code changes
- **Better user experience**: Works out of the box with no setup
Platform-specific wheels are automatically selected by pip during
installation based on the user's OS and architecture.
