Show HN: Git extension for controlling Git worktree mess

Score: 8.0/10 (Innovation: 8, Technical: 8, Documentation: 9, Utility: 7)

Zit is a git extension that enables multiple concurrent coding sessions (humans or AI agents) on a single repository using copy-on-write workspaces instead of full worktrees, with symbol-level change footprints to prevent semantically conflicting merges. It tracks and claims files/functions/sections to coordinate parallel agents, preserves each change's rationale and cost in commits, and keeps the underlying git history plain for interoperability. Its benchmarks show significant disk savings and higher agent success rates with claims.

Target audience: backend developers, devops, AI coding agent users, engineering teams
