Where new context tokens (cache writes) came from. Categories describe what was added; the Main/Subagent split shows which agent caused it (subagents do reads, writes, and conversation too). Cost is the cache-write portion only — see the per-model table above for the full session cost. Total accounted: {{ "{:,}".format(cost_ctx.bloat_total_tokens) }} tokens / {{ cost_ctx.bloat_total_cost }} of cache writes.
