What your Claude Code sessions look like — before vs after Tacit On the left, a terminal showing raw JSONL output from a 454-message Claude Code session, 2.3 megabytes of unreadable JSON. An orange arrow labeled "~2ms" points to the right, where Tacit has extracted the same session into a structured report titled "Refactor store pattern for archive module" with five sections: Intent, Decisions, Blockers, Outcomes, and a Phases timeline.
