# Get Claude Code session

Automatically get Claude Code session on claude.ai. Full transcript of one Claude Code web session by id, oldest→newest. The transcript is virtualized — only the messages near the viewport exist in the DOM — so this walks it from the top and stops on the count the list itself declares (aria-setsize), rather than guessing when it has seen everything; a read it cannot complete throws instead of returning a partial transcript that would look whole. Each message carries its own id, who sent it (human, assistant, or neither for a system card like "Context cleared"), and the readable text of what the page shows for that turn — prose plus the tool cards' own summaries, in reading order. No timestamp: the page only holds an absolute one in a per-message hover tooltip.
