### Install (per project)
Add to the project's `.pi/settings.json`:
Run inside the target project folder (uses the standard `~/.agents` workflow — see the nixos-workflow skill):
```json
{
"packages": ["npm:pi-langfuse"]
}
```text
/config-add ext pi-langfuse
/reload
```
Restart pi — it installs the extension into `.pi/npm/` and picks up the config automatically.
pi installs the extension's npm dependencies automatically (deps are gitignored in `~/.agents`).
### Global install (all projects / machines)
