If you're working with Claude Code or Codex CLI and need to review your session history in a readable format, this skill converts those JSONL session files into clean markdown transcripts. It handles single sessions or batch processes entire directories, with optional flags to include tool calls and thinking blocks if you want the full context. Already picked up 122 installs, which makes sense because digging through raw JSONL to understand what happened in a conversation is nobody's idea of a good time. The extraction is straightforward Python that does one thing well without trying to be clever about it.
