The key press might land in 200 milliseconds; it might land seven minutes later, after I've been pulled into a meeting and come back. The trick is that Claude Code's hook timeout is 600 seconds, which turns out to be just enough headroom to hold the HTTP response open the whole time and let a hardware button write the answer. </div> <nav class="series-progress" aria-label="Series progress"> <span class="series-progress-label">Building ClaudeDeck · Part 6 of 10</span> <ol class="series-progress-dots"><li class="series-progress-dot is-done"> <a href="https://nick-liu.com/posts/claude-code-hooks-reality/" title="The Claude Code hooks docs are wrong.

The reality: vibe coding changes *what* senior engineers do, not *whether* we're needed. And the gap between experienced and inexperienced developers is getting wider, not narrower. </div> <p>Collins Dictionary named &ldquo;vibe coding&rdquo; their Word of the Year for 2025.

But pointing an AI at a folder of markdown files and hoping for the best doesn't work. What matters is how you structure the knowledge base. Get that right, and Claude becomes genuinely useful. Get it wrong, and you get confident garbage. </div> <p>There&rsquo;s been a wave of posts about this combo lately: <a href="https://x.com/jameesy/status/2026628809424781787" target="_blank" rel="noreferrer">James Bedford&rsquo;s full walkthrough</a>, <a href="https://x.com/gregisenberg/status/2026036464287412412" target="_blank" rel="noreferrer">Greg Isenberg&rsquo;s &ldquo;personal OS&rdquo; approach</a>, <a href="https://x.com/kepano/status/2008578873903206895" target="_blank" rel="noreferrer">kepano (Obsidian&rsquo;s CEO) sharing Claude Skills</a>.
