+description: "Scheduled check that the model you use in Hermes has not quietly got worse: 34 fixed, exactly graded questions (reasoning, instruction following, Japanese, plus your own) run through Hermes cron, each run tested against the same model's own baseline with an exact per-question test and a same-day confirmation run, and a message only for a confirmed drop, a changed served model or a failed measurement. Not yet tried against a real LLM API (checked with a local mock model and real Hermes cron). Disclosure: each check calls your own model through ctx.llm on your bill, capped per check by the plugin (default 120,000 tokens / $0.50; the scheduled agent turn is extra); price lookup goes through Hermes's pricing code; 10 optional code questions, off by default, would run model-written Python in a child process; creates one Hermes cron job when you run `schedule` (remove with `unschedule`); writes run history to plugin-data/model-drift-watch; no telemetry."
