Agent Deck
A native macOS app that wraps the Pi coding agent's CLI sessions in a SwiftUI workspace, giving each session and subagent its own visible, isolated git worktree.
Agent Deck is a native macOS workspace built around the Pi coding agent, launching the CLI a user already has installed in JSONL RPC mode rather than replacing it with a web wrapper or separate runtime. It shows which agents, skills, prompts, and commands are active and what scope they carry, keeps built-in resources read-only while showing overrides and write targets before work begins, and gives report-only subagents their own artifacts instead of writing into a user's project.
Sessions and subagents run in isolated git worktrees so parallel work does not collide, with status tracked in one place and merged back when the user chooses. It supports content-hugging message cards, a live transcript, tool calls, plans, file previews, project-specific Markdown memory with secret scanning, and a Doctor tool to find, install, and update Pi.
It is a signed and notarized SwiftUI application with no Electron or embedded web UI, distributed under the MIT license.
