Claude Code shipped a 60-second auto-continue misfeature with no changelog entry

Claude Code: Anatomy of a Misfeature

Olaf Alders details how Claude Code v2.1.198 introduced a 60-second timeout that lets the agent proceed without human input—shipped with no changelog entry and no documented off switch. He used Claude itself to reverse-engineer the minified JS bundle and confirmed the logic was buried with no standalone feature flag. Anthropic shipped a fix two days later, but the incident shows Claude Code's auto-update can silently push surprising defaults, and users have almost no visibility into what changed.

Why it matters: A well-sourced reverse-engineering post: the author pinpointed a 60-second auto-execute timeout silently added to Claude Code v2.1.198 on July 1, with no changelog entry and no independent toggle. HKR all hit, but it's a single blog post, not an official announcement — cap at 78.
