Show HN: Graft – Claude Code hooks that cut grep tokens by 42%

Graft is a tool that optimizes Claude Code and other AI coding agents by reducing token usage by 42% and improving correctness by 12 percentage points through contextual code understanding. The open-source project integrates with coding agents via hooks and achieves up to 4× cost reduction and 3× faster performance by intelligently selecting relevant code context rather than relying on grep-based searches. Installation is simple with `graft init`, which builds a local graph cache and automatically integrates with Claude Code without requiring ongoing maintenance.
