I often tell Claude Code to look at previous sessions in ~/.claude and it’s happy to jq/grep its way through them with no special tool. But being more efficient is always good.
Claude has been heavily RL'd on using jq/grep, even if the tool is more efficient, Claude using it incorrectly or reading a book of examples in order to understand how to use it correctly is going to end up underperforming.
