Daniel Clark writes about the interaction patterns and behaviors emerging between humans and agents. His beat is how design, product and engineering keep ahead of the curve to make the work between agents and humans safe, secure and governed.

Claude Code and Codex hand finished work back the same way

The reverse of delegation was always the weaker half of the loop. It just cleared the promotion bar.

Delegation gets all the attention — the brief, the scope, the dispatch. But the return leg is where trust is actually won or lost: how does finished (or stuck) work come back to a human?

Human Handoff cleared the promotion bar this week: Claude Code's session-summary-plus-diff handoffs and Codex's diff-as-product-surface make two independent vendors solving the same problem with screenshots to prove it.

The anatomy that emerged from the sightings: a summary (what was done), a diff (the reviewable artifact), decisions (choices made on your behalf), open questions (what couldn't be resolved), and next actions. The most interesting tension: the summary is written by the party being reviewed.

The page is live at /patterns/human-handoff, and this story is the start of its thread — every future sighting, status change, and story accumulates there.
