DAATUUM

The real-time coordination layer for teams of developers running Claude Code agents.

Core trick

Hook writes each agent's file changes to a shared live store and flags conflicts with other agents' contracts at the next write.

Description

The real-time coordination layer for teams of developers running Claude Code agents. Git coordinates code at rest; Datum coordinates agents in motion. A team does spec-driven development right — shared spec, common CLAUDE.md, PRDs split per engineer — then implementation starts and truth changes. One agent renames a column or swaps a dependency, and the others keep building against a contract that no longer exists. The drift surfaces at merge, after the rework is paid for. datum is the live source of truth that catches it at the next write instead.
