Adds GitHub Copilot's **Raptor mini** model (`oswe-vscode-prime`) to [pi](https://github.com/badlogic/pi-mono).

## Why

pi's model catalog is baked in at build time. Raptor mini went to public preview on 2025-11-10, after the catalog was last regenerated, so `pi --list-models` doesn't show it. This extension adds it at runtime.

When pi-ai picks it up upstream, this extension becomes a no-op (it detects the duplicate, warns, and exits).

## Install

```bash
pi install npm:pi-extension-raptor-mini
```

> The `npm:` prefix is required. `pi install pi-extension-raptor-mini` is interpreted as a local filesystem path, not an npm package.

Alternatives:

```bash
pi install git:github.com/WSeubring/pi-extension-raptor-mini   # from git
pi -e /path/to/pi-extension-raptor-mini                        # local checkout, no install
```

## Use

```bash
pi --list-models | grep oswe
# github-copilot  oswe-vscode-prime  264K  64K  no  no

pi --provider github-copilot --model oswe-vscode-prime -p "hello"
# or match by name substring:
pi --model raptor -p "hello"
```

You need to be logged into Copilot in pi (`/login github-copilot` inside the interactive UI, or pi prompts on first use). Any Copilot plan works — Free, Pro, Pro+, Business, Enterprise.

## Heads-up

pi's `github-copilot` provider talks to Copilot's API with VS Code's own integration headers (`Copilot-Integration-Id: vscode-chat`, etc.). That's how Copilot models — including Raptor mini — are reachable at all. This behavior predates this extension and applies to every request pi's Copilot provider already makes; installing this extension doesn't change the request shape, just adds one model id to the catalog.

GitHub's [AUP](https://docs.github.com/en/site-policy/acceptable-use-policies/github-acceptable-use-policies) prohibits misrepresenting client identity; in practice, enforcement has targeted automation/volume abuse rather than client-identity alone. If you want zero ambiguity, use pi's `anthropic` / `openai` / `google` providers with your own API keys instead.
