Pi stays the harness. The Devin CLI owns login and the live model catalog (devin auth, devin models list). This is not an ACP integration and does not use Zed.

Why this exists

pi-devin-auth treated Devin as Cascade cloud chat. Models like Sol High, Opus 5, and Fable 5 then failed with:

This model is only in Devin Local.

Those models are available through the local Devin CLI. This package uses that CLI for auth + catalog, then streams completions into Pi so Pi's tools, sessions, and UI stay in charge.

Requirements

Pi Coding Agent 0.86+ (managed fork validated against 0.87.1)
A signed-in Devin CLI (devin auth status)
Node 22.19+

The CLI binary is resolved in this order:

$DEVIN_CLI
~/.local/bin/devin, Homebrew, /usr/local/bin/devin
Devin.app's bundled devin binary
which devin

Install

From git:

pi install git:github.com/kashyab12/pi-devin

After npm publish:

pi install npm:pi-devin

Local checkout:

pi install /Users/kashyab/pi-devin

Restart Pi or run /reload.

Usage

/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 the Devin CLI or Devin Desktop, 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 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	An editor host for Devin

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.

Managed fork

Based on npm pi-devin 0.2.1. Retains native signature/response replay, corrected wire fields, bounded frames, context clamping, multi-window catalog variants and abort cleanup. Uses the upstream six-hour XDG catalog cache. Tests and typecheck are maintained in the parent app tests directory.
