Context engineering

Handoff artifact

Also called: handoff note

A handoff artifact is the concrete document produced at a handoff, recording what is done, what is next, and the key decisions. The next session reads it to get up to speed fast.

A handoff artifact is the actual document a handoff produces. The handoff is the act of passing work on; the artifact is the note that carries it: a short, written record of the state of play that the next session or agent reads first.

What a good one contains

It is not a transcript. It is a distilled summary aimed at getting a fresh agent productive in one read:

  • Goal: what we are trying to build and why.
  • Done: what works and is confirmed.
  • Next: the immediate next steps, in order.
  • Decisions: the choices already made, so they are not relitigated.
  • Pointers: paths and links to the primary source files that matter.

Why write it down

Because a fresh session starts with an empty context. The artifact is the seed you plant to fill it with the right stuff, fast. It functions much like a mini spec: written context that tells the agent what to do next and why, without making it reverse-engineer the whole history.

Tip
Have the outgoing agent write the artifact, then read it back yourself before trusting it. If the summary is vague or wrong, the next session inherits the confusion. A minute of review here saves a derailed restart.
