Parse, analyze, and extract information from Claude Code or Claudia session JSONL files. Supports two formats automatically — Claude Code (pretty-printed JSON with user/assistant/queue-operation records) and Claudia (strict JSONL with alternating request/response pairs). Use this skill whenever the user mentions a .jsonl session file, asks about token usage or costs from a Claude session, wants to review what happened in a conversation, asks to extract tool calls or thinking blocks, mentions "session file" or "session log", wants to summarize or search through a past interaction, or references a file path that looks like a session ID (UUID.jsonl) or thread timestamp (1234567890.123456.jsonl). Also trigger when the user pastes a Slack thread URL and wants to analyze, download, or review that conversation's session, when they want to compare sessions, debug a failed tool call from a log, or convert session data into another format.
