Show HN: Heddle- ATC for Your Subagents (github.com)

Heddle, a newly unveiled tool previously known as loom-vcs, functions as an "air traffic control" system for coding agents working simultaneously on shared Git repositories. By introducing the concept of "intent leases," Heddle allows multiple agents to declare their goals and the files they will edit before they start working, significantly reducing the chances of code collisions and messy rewrites. Unlike traditional Git, which reports conflicts only after edits have been made and tokens expended, Heddle warns agents of potential overlapping work upfront, enabling better coordination and self-partitioning of tasks. Each agent operates in their isolated worktree, ensuring that their respective changes do not overwrite each other, while still advancing a green mainline through consented merges. The significance of Heddle for the AI/ML community lies in its potential to streamline collaborative coding workflows, especially as machine learning models become more complex and require iterative refinements by multiple agents. By prioritizing isolation and coordination, Heddle minimizes costly semantic reconciliations that can occur when agents simultaneously modify the same code. Its decentralized structure, combined with features such as human consent gates for integrations and management of orphaned tasks, promises a more efficient approach to collaborative development and recovery in environments where multiple agents are continually operating. This innovation signals a move towards smarter, more collaborative coding practices that can better handle the intricacies of modern software projects.
