+# pi-devin
+
+A [Pi](https://pi.dev) package that uses **Devin Local** models inside Pi.
+
+Pi stays the harness. The local [Devin CLI](https://docs.devin.ai/cli) owns login and the live model catalog (`devin auth`, `devin models list`). This package does **not** wrap Devin as an ACP agent and does **not** use the old `pi-devin-auth` cloud-only shim.
+
+## Why this exists
+
+`pi-devin-auth` treated Devin as Cascade cloud chat. Models like Sol High, Opus 5, and Fable 5 then failed with:
+
+```text
+This model is only in Devin Local.
+```
+
+Zed works because it launches `devin acp` — Devin Local. This package uses that same local CLI for auth + catalog, then streams completions into Pi so Pi's tools, sessions, and UI stay in charge.
+
+## Requirements
+
+- Pi Coding Agent 0.80+
+- A signed-in [Devin CLI](https://docs.devin.ai/cli) (`devin auth status`)
+- Node 18+
+
+The CLI binary is resolved in this order:
+
+1. `$DEVIN_CLI`
+2. `~/.local/bin/devin`, Homebrew, `/usr/local/bin/devin`
+3. Devin.app
+4. Zed's ACP registry install (`~/Library/Application Support/Zed/external_agents/registry/devin/.../bin/devin`)
+5. `which devin`
+
+## Install
+
+Local (this repo):
+
+```bash
+pi install /Users/kashyab/pi-devin
+```
+
+After you publish to npm:
+
+```bash
+pi install npm:pi-devin
+```
+
+From git:
+
+```bash
+pi install git:github.com/<you>/pi-devin
+```
+
+Restart Pi or run `/reload`.
+
+## Usage
+
+```text
+/login devin
+/model devin/claude-opus-5-high
+/model devin/claude-5-fable-high
+/model devin/gpt-5-6-sol-high
+```
+
+`/login devin` runs `devin auth login` if `~/.local/share/devin/credentials.toml` is missing. If you already signed in through Devin Desktop, the CLI, or Zed, that file is reused.
+
+Commands:
+
+- `/devin-status` — CLI path, version, auth
+- `/devin-refresh` — reload `devin models list --format json`
+
+## What this is / is not
+
+| This package | Not this package |
+|---|---|
+| Pi is the agent | Devin ACP taking over the session |
+| Devin CLI for auth + catalog | Fake Windsurf OAuth paste flow |
+| Live CLI families (Opus 5, Fable 5, Sol, …) | Hardcoded 11-model cloud allowlist |
+| Completions streamed into Pi tools | `devin acp` as the editor host |
+
+## Publish
+
+This is a standard Pi package (`keywords: ["pi-package"]` + `pi.extensions`). After you push to npm with that keyword, it can show up on [pi.dev/packages](https://pi.dev/packages).
