   Thanks for reporting this! To work out whether this is a bug in OpenCode or the model just repeating itself, could you add a few details?

   • The exact output of opencode --version ("latest" doesn't tell us which version you're on)
   • Roughly what you asked the agent to do, and whether it was the main agent or a subagent
   • How many times the same read repeated, and whether it stopped on its own or you had to interrupt it
   • Whether OpenCode showed a permission prompt about a repeated tool call (the doom_loop check, which should ask after 3 identical calls)
   • If you can, a screenshot or an export of the session (/export)

   You can reply here with the details or edit the issue. If you edit it, please also leave a comment saying you've updated it, so we know you're done.

   These related issues might already cover your problem. They are ordered from most to least likely:

   • subagent: infinite loop of identical tool calls for ~50min with no loop protection, uncontrollable token burn #45442: an agent repeats identical tool calls in a loop with no loop protection (reported on v1)
   • Bug Description: LongCast 2.5 Preview enters an infinite loop while reading files. #52884: a model gets stuck re-reading the same files without making progress (v1, closed)
   • [OpenCode Go] muse-spark-1.3-contributor gets stuck in repeated Read/Search loops and fails to progress to edits #47992: a model gets stuck in repeated Read/Search loops instead of moving on to edits (closed for missing details)

   We're closing this for now because we didn't get the details we asked for. Without your exact opencode --version, what you asked the agent to do, and how the loop behaved (how many repeats, whether it stopped on its own, whether the doom_loop prompt appeared), we can't tell whether the repeated reads come from OpenCode or from the Beam Free model.

   If it happens again, please reply here with those details or open a new issue, and we'll gladly take another look. #45442 tracks a related problem with repeated tool calls and loop protection, if you'd like to follow it. Thanks!
