# Beacon

Asymptote Labs has open-sourced Beacon, a memory layer that works across agent harnesses. Previously, switching among coding agents such as Claude Code, Codex and Cursor meant re-explaining tasks, workflows and common mistake patterns, and the team found no good free alternative. Beacon hooks into more than 20 agent harnesses, normalizes session telemetry such as prompts, tool calls and command executions into one format, distills it into reusable patterns with a human-approval step, and exposes the result to later agents through skills or MCP.
