pi-ember-stack

The Ember-owned pi package. It installs the complete Ember agent workflow as one package:

• Primary modes: /coder, /architect, /doctor, /orchestrator, and /ui-doctor.
• Inline questionnaire UI for decision-oriented questions. Agents are told to prefer it when they need a user choice.
• A compact native edit renderer that shows the filename and a single +N / -N result row.
• Vendored subagent support with bundled coder and architect definitions, plus the upstream bundled roles.
• Bundled Devin auth/provider support, including OAuth, model catalog refresh, and streaming transport.
• Cursor subscription support through the official Cursor Agent CLI, with Pi retaining its native session and tool loop.
• A self-contained Ctrl+Space mode-cycle shortcut and a footer showing the active mode, model, and thinking variant.

Plugin registry

The package has one top-level pi extension which dispatches to the internal plugins under plugins/. Enable them globally in PI_HOME/pi-ember-stack.json:

{
  "plugins": ["pi-compact-tools", "pi-custom-agents", "devin-auth", "pi-cursor-auth"]
}

Remove a plugin ID to disable it, or use /stack-plugins to toggle one from the TUI. Restart pi after changing the list. The available plugins are:

• pi-compact-tools: collapsed native edit rendering.
• pi-custom-agents: questionnaire UI, primary modes, plans, subagent tool, and bundled agent definitions.
• devin-auth: Devin provider, OAuth, catalog refresh, and streaming.
• pi-cursor-auth: Cursor subscription auth, model refresh, and native Pi streaming.

Project setup

The Ember repository contains a project-local .pi/settings.json entry for:

"npm:@nmzpy/[email protected]"

On a new clone, start pi from the project directory. Pi will ask for a one-time project trust decision before it installs the package into the project-local .pi/npm/ directory. The same decision can be approved non-interactively with:

pi --approve

Project trust is intentionally a user decision; a repository cannot safely bypass it. After trust, normal startup is just pi from the Ember directory.

When a new version is intentionally released, update the pinned version in the project settings and run:

pi update --extensions

Third-party utilities such as pi-fff and image paste remain separate package entries. Devin auth is now bundled as a stack plugin, but credentials and provider secrets stay in the machine-local pi configuration and are not part of this repository.

Development

The package entrypoint is plugins/index.ts. Compact tools are under plugins/pi-compact-tools/, while questionnaire, primary modes, plans, subagents, and bundled agents are under plugins/pi-custom-agents/. Provider plugins are under plugins/devin-auth/, plugins/pi-cursor-auth/, and plugins/xai-auth/.

Run the package typecheck with:

npm install
npm run typecheck

Release

Run ./gacp.sh --release to bump the patch version, typecheck, commit, tag, push, and publish the package to npm. This only publishes the package; update Ember's pinned package version separately when you want the project to install it.

The package is cross-platform: bundled paths are resolved from import.meta.url and do not depend on a Windows home directory or the current working directory.
