Stash is our attempt to give non-coders Codex superpowers: proactive agents that do not just analyze, but actually act on the toughest problems right where you are. Stash is a macOS overlay where you drop anything related to a project, PDFs, notes, links, snippets, half-formed questions, without breaking flow. Instead of bouncing between folders, chats, and tools, Stash becomes a single project surface where a sidekick team of GPT-5.3 agents goes to work for you. Under the hood, Stash spins up parallel agents running in isolated worktrees: one investigates, another drafts, another fixes, another produces concrete artifacts like markdown files, CSVs, or scripts. You do not ask for “answers”, you ask for outcomes, and everything is inspectable and grounded only in the materials you provided.
