Ellipsis APIReferenceSessions

Get Agent Session Executions

Return the session's executions with their launch context — most notably system_prompt_append, the text Ellipsis appends to Claude Code's default system prompt (platform section + response instructions + the config's customer instructions). Per execution because each cold wake persists its own launch config (a config edit or replay override between wakes changes it).
