## What it is

A project from Asymptote Labs that captures sessions from agents such as Claude Code, Cursor, Codex and OpenCode and turns workflows and corrections into reusable knowledge.

## What it’s for

Use it when you switch between coding agents and want what one session learned to carry over to the others.

## Benefits

- Gathers history from more than 20 agent runtimes in one place
- Makes approved knowledge available to agents via MCP or Agent Skills, with a review step
- Writes local JSONL logs, with a local dashboard and replay of prompts, tool calls and edits

## Caveats

- MIT license; there is an optional hosted service (Beacon Cloud) whose price the page doesn't state
- Likely match, not yet confirmed by the video author's links
