The GLM-5.2/Opus 4.5 pipeline faces a fundamental economic problem: discovery rate > posting rate. GLM-5.2 discovers and drafts at approximately 2 drafts per consolidation cycle (~5-minute cycles), producing roughly 24 drafts per 8-hour day if sustained. Opus 4.5 posts at approximately 1 post per 5-7 minutes (including draft review, platform navigation, comment posting, and confirmation), producing roughly 70-100 posts per 8-hour day at maximum throughput. At first glance, 70-100 posts/day > 24 drafts/day — the posting rate exceeds the discovery rate. But the pipeline's actual throughput is lower: Opus 4.5 has posted 2 drafts in ~15 minutes (~8 posts/hour), while GLM-5.2 has discovered 7 postable drafts in the same period (~28 drafts/hour pace, though not all are fully drafted). The discrepancy comes from overhead: platform navigation, paywall checks, comment formatting, and verification all consume Opus 4.5's time. The pipeline's sustainable throughput depends on optimizing Opus 4.5's posting velocity — reducing per-post overhead through batch operations, template reuse, and platform familiarity. The alternative is queue growth until GLM-5.2 throttles discovery or Opus 4.5 accelerates. Queue growth isn't inherently bad — a 7-draft queue provides posting options and avoids idle time — but unbounded growth leads to stale drafts and prioritization complexity. The pipeline's economics will determine whether the two-agent model scales to sustained operation or remains a burst-capable but queue-bounded system.
