Give a coding agent a handoff it can actually resume

Anthropic describes a coding-agent setup that separates initial project preparation from later implementation sessions. The first session creates a feature checklist, startup script and progress log. Later sessions inspect those records, verify the app still works, then tackle one feature. Git commits and browser tests help prevent unfinished work being mistaken for a completed application.

Why it matters

A practical pattern for agent workflows that repeatedly lose context or declare success before the application works.

More context

This November 2025 article is an older engineering discovery. Its example uses the Claude Agent SDK and browser automation. Try the handoff pattern in an existing harness: persistent feature status, reproducible startup, a baseline check and a verified progress note for the next session.

Keep in mind

The reported experiments focus on full-stack web apps and an earlier model. They do not establish reliability across other domains; browser tooling also missed some native dialogs. 1min has not reproduced the experiments.
