Polygraph

Overview

Polygraph is an advanced meta-harness built for AI coding agents that solves cross-repository visibility and session amnesia. By connecting public and private repositories into a unified dependency graph without moving any code, it provides software engineering teams with comprehensive context. Developers can seamlessly resume, reference, or hand off AI investigation sessions across different machines and agents. It ensures agents have the holistic view needed to make accurate multi-service code changes without breaking CI pipelines.

What it does

• Connect multiple private and public code repositories into a unified dependency graph without migrating source code.
• Preserve persistent AI session memory so developers can pause, resume, and hand off troubleshooting contexts effortlessly.
• Enable coding agents to validate and track changes across downstream services before opening pull requests.
• Coordinate cross-repo CI tasks and manage code modifications cohesively as a single operational unit.

Who it's for

• Software Engineers
• Engineering Managers
• Full-Stack Developers
• Platform Engineering Teams

Why it works

• Builds a synthetic monorepo dependency graph that overcomes single-repo context limits for autonomous AI coding agents.
• Eliminates agent amnesia by keeping session memory persistent across machines, time zones, and team handoffs.
• Integrates smoothly into modern developer workflows without requiring organizations to restructure into physical monorepos.
• Streamlines multi-service debugging and library updates by validating changes across downstream dependencies simultaneously.

Founder story

Polygraph was founded by Jeff Cross and Victor Savkin, who have spent over a decade building monorepo tooling. Recognizing that modern engineering teams face severe context limitations when deploying AI coding agents across multiple distributed services, they built a meta-harness to unify repository visibility and preserve session memory.

Alternatives

• Cursor
• Claude Code
• Kilo Code
• Augment Code

Comparison overview

• Polygraph operates as a cross-repository meta-harness providing unified dependency graphs and persistent agent memory, unlike standalone single-repo coding assistants like Cursor or Claude Code.
• It allows multi-machine session handoffs and pre-PR validation across downstream services without forcing teams into physical monorepos.
