# pi-plugins

High-quality, single-purpose plugins for the
[pi-agent](https://github.com/earendil-works/pi) harness, built on
[Effect-TS](https://effect.website) primitives.

Each plugin does one thing well: clear inputs, predictable outputs, and an
implementation that leans on Effect for typed errors, resource safety, and composable
concurrency.

## Requirements

Pi **0.80.10 or newer** is required.

## Usage

Install a published plugin with pi-agent:

```bash
pi install npm:@pi-plugins/webfetch
```

Or try it for a single run without adding it to settings:

```bash
pi -e npm:@pi-plugins/webfetch
```

For local development, load a plugin directly from its package directory:

```bash
pi -e ./plugins/webfetch
```

Then ask pi to use the tool it registers — for example, to fetch a URL.

## Nix

This repo contains a Nix flake with a development shell for local checks.

```bash
nix develop
ci
```
