Find a past Claude Code session on this machine by project or topic, then summarize what was done in it. Use when the user asks "which session did I do X in", "find the session where I worked on Y", "in project ~/path I worked on Z — find and summarize that session", "what was I doing in <project> last week", or wants to locate/recall/analyze a previous Claude Code conversation. Reads local ~/.claude/projects transcripts. Not for searching code, git history, or the current live session.
