Optimizes local storage by pruning bloated Claude Code conversation history and truncating large tool outputs.
The History Pruner skill is an essential maintenance utility for developers using Claude Code who experience disk space issues or performance lag caused by accumulating conversation logs. It intelligently scans project JSONL files to truncate massive tool outputs and remove outdated snapshots while preserving essential message structures and summaries. By keeping project files below the 50MB threshold, it ensures faster synchronization across devices via tools like ClaudeSync and prevents GitHub sync failures due to oversized files, all while maintaining Claude's ability to handle context gracefully.
