&lt;p class="" style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5"&gt;Here’s a scenario I’ve been thinking about a lot: You’re running Claude Code in &lt;a href="https://7751c435.click.kit-mail3.com/r8ux2n7lppt9u2vkx6ga2hd0oz7exbwee77x67qdmn40zme9rrgvowex4n4d5wxzxpmd6zevegko2w5qw50pzwgz3p45725982mqex8o2d8kn87lxwloz3lzoxqh33ggk/e0hph0u7okrxvru7/aHR0cHM6Ly9kb2NzLmRvY2tlci5jb20vYWkvc2FuZGJveGVzLw==" target="_blank" class="ck-link" rel="noopener noreferrer" style="color:#0875c1" url-id="1849941308"&gt;Docker Sandbox&lt;/a&gt; – let it loose, let it work autonomously, no permission prompts. It’s powerful stuff.&lt;/p&gt;
&lt;p class="" style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5"&gt;But then it happens. One bad command. A &lt;code&gt;git reset --hard&lt;/code&gt;. A &lt;code&gt;git push --force&lt;/code&gt;. Your entire week of work, gone.&lt;/p&gt;
&lt;p class="" style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5"&gt;Docker Sandbox isolates &lt;em&gt;where&lt;/em&gt; Claude runs code, but it can’t stop &lt;em&gt;what&lt;/em&gt; commands it executes inside that sandbox. Your git history is sitting right there, unprotected.&lt;/p&gt;
&lt;p class="" style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5"&gt;I just built a skill to fix this – a guardrail that blocks dangerous git commands before Claude even touches them. Think of it as a bouncer at the door, checking IDs and making sure nobody tries to sneak in with &lt;code&gt;git reset --hard&lt;/code&gt;.&lt;/p&gt;
&lt;p class="" style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5"&gt;In today’s article, I’ll show you how to install these guardrails and customize them for your workflow.&lt;/p&gt;
&lt;p class="" style="margin:1em 0;font-family:-apple-system,BlinkMacSystemFont,'Segoe UI',Roboto,Oxygen-Sans,Ubuntu,Cantarell,'Helvetica Neue',sans-serif;color:#2d2d2f;font-size:16px;line-height:1.5"&gt;If you’re playing with autonomous workflows (or any kind of AI agent), this could be a lifesaver.&lt;/p&gt;
