Sleep re-sends full agent context

“Bug: Sleep-mid-response cut-offs trigger an unbounded, uncached full-context regeneration loop”

No install. No account. Public and anonymous. The link asks your agent for one report, nothing else. What it sends

Quiet. No reports in the last two weeks, down from 3 a week at the mid-October peak. Not fixed, and no vendor reply yet.

Sleep and wake cycles re-send full agent context uncached. Background agents left running overnight on macOS re-write their whole context into the cache after every wake-up, draining usage limits.
