oh-my-pi is moving fast on features and the issue tracker is keeping pace. A new isolated Grok Build subscription provider landed as an open PR, but three reports in the same window point at stability problems you will feel the moment the agent is idle on your machine.
The agent sits at ~50% CPU doing nothing
The sharpest one: a report that the agent consumes roughly 50% CPU while doing almost nothing beyond animating. On a laptop that is the difference between a quiet fan and a space heater. The reporter ties it to the idle loader animation — the spinner keeps the event loop busy enough to peg a core. If you run this agent in the background while you work, that is real battery and thermal cost, not a cosmetic nit.
RPC mode dies on a bad line
A second report: RPC mode (--mode rpc) crashes the whole process on any non-JSON stdin line. RPC mode is how you embed the agent in a larger pipeline, so a single malformed frame taking down the process means your orchestrator needs to assume oh-my-pi can die at any time. A sibling commit does add a fix to keep RPC stdin alive after bad JSONL frames, which signals the maintainers saw this and are hardening it — but the crash report is still open.
A Bun binary pointing at CI paths
The third is a build bug: the Bun-compiled binary contains hardcoded GitHub Actions paths (/home/runner/work/...), causing an ENOENT when the extension loads anywhere else. That is the classic “it works in CI” trap — the release artifact quietly depends on a path that only exists on the build machine.
Read the room
Features like the Grok Build provider are a signal the project wants to be your daily driver across models. But a 50% idle CPU spin and a fragile RPC mode say the daily-driver surface is not there yet. If you self-host an agent for long sessions, thermal and crash behavior matter more than the provider count. The local-first architecture piece on Hermes lays out why running agents on your own hardware makes these stability bugs something you can actually patch instead of wait on a vendor to fix.
