## Sound familiar?

- The same problem comes back in the next project.
- Start a new session or switch agents, and you are explaining the context and rules all over again.
- Plans, progress, and conclusions are scattered, so the agent keeps jumping between old and new directions.
- You know the answer exists. It is just buried somewhere in an old chat.

## What Project Cairn does

Project Cairn is an agent skill. During normal project work, it helps the agent keep validated pitfall lessons, key decisions, exploration findings, and sparks of insight inside the project. When something is genuinely reusable elsewhere, the agent can prepare it for a long-term knowledge base after you confirm it.
