It indexes all connected repositories into a graph, enabling agents to plan and execute cross-repo tasks without manual guidance, and allows session handoffs between agents. The tool is free during early access.", "body_md": "See everything, forget nothing\n\nSee everything, forget nothing\n\nSee everything, forget nothing\n\nThe meta-harness that gives agents what they're missing: visibility across every repo boundary, and memory that survives every session.\n\nThe meta-harness that gives agents what they’re missing: visibility across every repo boundary, and memory that survives every session.\n\nThe meta-harness that gives agents what they’re missing: visibility across every repo boundary, and memory that survives every session.\n\nCross repo unity\n\n## Prompt once. Land everywhere.\n\nPolygraph indexes every repo you have access to (private and OSS) and builds a graph of how they relate via packages and APIs. Your agent uses this to plan cross-repo work without being told where to look; turning your codebase into a synthetic monorepo.\n\nPolygraph isn't an agent.
