161161Steps 1 and 2 are [starting a session](#start-a-session): a message tags Claude in, and a sandbox builds for that thread. Step 3, the working loop, is [the checklist](#how-the-checklist-updates) below. Steps 4 and 5, the result and the quiet period that follows, are covered in [What survives between replies](#what-survives-between-replies).

163Every session runs in an ephemeral sandbox Anthropic hosts, a real working environment where it can read documents, run code, build charts, and open pull requests. Claude clones your repositories into the sandbox, edits them there, and pushes changes back to your Git host as a branch or pull request. The sandbox runs the same engine that powers Claude Code on the web, Anthropic's agent for writing and running code, which is why the results are working artifacts rather than chat.
