3 sessions on odin with a coding agent: the agent failed at least once in 3, and 0 finished without a human stepping in.
Takeaway: Next time I'd tell it upfront to always launch background threads (HTTP listener, per-connection handlers) as self-cleaning/detached instead of calling thread.destroy, since that single join call silently blocked the whole game window from ever opening.
Takeaway: Next time I'd spell out exact screen resolutions and the grid/sidebar split ratio in the very first prompt instead of iterating three times on layout — that back-and-forth cost more turns than any of the actual milestone work.
Takeaway: Next time I'd specify the exact layout rule (like the 80/20 split) up front instead of letting the agent guess at pixel dimensions per resolution — that's the correction that actually simplified the code.
