Workflow

If an import error occurs, extract the module name.
Map module name to package name if different (see table above).
Check if already installed:
```
uv pip show <package>
```
If not installed:
```
uv pip install <package>
```

Troubleshooting

Common issues

Problem	Solution
`uv: command not found`	Install uv: `curl -LsSf https://astral.sh/uv/install.sh \| sh`
Package installs but import still fails	Check you're in the correct venv: `which python`
Version conflict	Pin version: `uv pip install package==1.2.3`
Build fails (C extension)	Install system deps: `brew install pkg-config` (macOS)
SSL certificate error	`uv pip install --trusted-host pypi.org package`

Notes

Always run from the project directory so the correct
```
.venv
```
is used.
Use
```
uv pip
```
(not plain
```
pip
```
) to ensure packages go into the uv-managed environment.
For packages with C extensions, ensure build tools are installed (
```
xcode-select --install
```
on macOS).
