Show HN: Shard – Stop watching one AI agent code for 45 min. Run four at once

The biggest bottleneck in AI-assisted coding right now isn't model quality. It's that you give Claude Code or Cursor a complex task and then sit there watching it work for 30-60 minutes. You can't intervene, you can't do anything useful, you just wait.

Shard takes that one big prompt and automatically decomposes it into a DAG of parallel sub-tasks. Each task gets exclusive file ownership so there are zero merge conflicts by design. Then it dispatches multiple agents across git worktrees simultaneously, merges in topological order, and self-heals test failures.

A 45 minute serial task becomes 4 agents running for 12 minutes.

Open source, cross-platform, agent-agnostic (Claude Code, Aider, Cursor).
