   For what it's worth, I had OpenCode make a plugin for me to do this. Haven't tested it much yet, but here it is:

   Edit: the code I posted doesn't clean up the block after OpenCode finishes work or exits

   import type { Plugin } from "@opencode-ai/plugin";
   import { spawn, type ChildProcess } from "child_process";
   
   export const SleepInhibitPlugin: Plugin = async () => {
     let inhibitorProcess: ChildProcess | null = null;
   
     function acquire() {
       if (inhibitorProcess) return;
       inhibitorProcess = spawn(
         "systemd-inhibit",
         [
           "--what=sleep",
           "--who=opencode",
           "--why=AI is actively working",
           "sleep",
           "infinity",
         ],
         { stdio: "ignore" },
       );
       inhibitorProcess.on("exit", () => {
         inhibitorProcess = null;
       });
     }
   
     function release() {
       if (!inhibitorProcess) return;
       inhibitorProcess.kill();
       inhibitorProcess = null;
     }
   
     process.on("exit", release);
     process.on("SIGINT", release);
     process.on("SIGTERM", release);
   
     return {
       event: async ({ event }) => {
         if (
           ["message.updated", "tool.execute.before", "session.updated"].includes(
             event.type,
           )
         ) {
           acquire();
         }
         if (event.type === "session.idle") {
           release();
         }
       },
     };
   };

   You can run systemd-inhibit --list --no-pager while OpenCode is working on something, and you'll see an entry in the list for it.

   Very surprised that there is no such option, especially when codex have had this since first version

   

   Personally use caffeinate -d on macos to prevent sleep.

   Personally use caffeinate -d on macos to prevent sleep.

   I prefer caffeinate -i so the display can save energy but the system is still working
