# Handoff artifact

Concept · [Building with AI](https://ecosystem.samcarlton.com/ai)

Also called: handoff document, handoff doc, handoff note, progress file, progress notes

The written document that carries a [handoff](https://ecosystem.samcarlton.com/handoff), produced by one [session](https://ecosystem.samcarlton.com/session) for another to read. It might be a plan, a ticket, a [summary](https://ecosystem.samcarlton.com/secondary-source) or a [to-do list](https://ecosystem.samcarlton.com/backlog) saved as a file.

**For example:** The [agent](https://ecosystem.samcarlton.com/ai-agent) saves a file listing finished steps, open questions and the next three tasks, and the next day's [session](https://ecosystem.samcarlton.com/session) reads it first.

- [Spec](https://ecosystem.samcarlton.com/spec): A written description of what is being built and why, for work too big to finish in one session.
- [Backlog](https://ecosystem.samcarlton.com/backlog): The running list of new abilities, fixes and ideas waiting to be worked on, usually in order of priority.
- [Secondary source](https://ecosystem.samcarlton.com/secondary-source): A description of the original material rather than the material itself, such as a summary, a README or a compaction note.
- [Filesystem](https://ecosystem.samcarlton.com/filesystem): The files and folders on a computer.
- [Memory system](https://ecosystem.samcarlton.com/memory-system): A setup that tries to give an agent memory across sessions by saving notes to files or a database and loading them back when a new session…
- [Clearing](https://ecosystem.samcarlton.com/clearing): Ending a session and starting a completely empty one.
- [Design concept](https://ecosystem.samcarlton.com/design-concept): The shared picture of what is being built, held by you and by the agent, separate from any document or code.
