Nx Launches Polygraph to Give AI Agents Cross-Repo Visibility and Session Memory

The New Stack·medium signal

Nx debuted Polygraph on June 25, 2026, a meta-harness that indexes all of a developer's repos (private and OSS) into a unified dependency graph — a 'synthetic monorepo' — so agents can plan cross-repo work without being told where to look, and resume any session created by any developer, machine, or agent. It hit the Product Hunt June 25 leaderboard and is currently offered free. It directly targets two of the biggest agent failure modes: repo-boundary blindness and lost session context.
