Hitting Max limits too fast — you or the platform?
#16157 "Instantly hitting usage limits with Max" has 720+ reactions. Before you conclude it's a bug, the first thing most people miss: your Pro/Max quota is shared across Claude and Claude Code. This check sorts how much of your fast burn is self-explainable from a possible anomaly worth reporting. Nothing leaves your browser.
Your plan
Other Claude surfaces you use heavily on the same plan (these share the quota)
Anthropic's docs: usage limits are "shared across Claude and Claude Code — all activity in both tools counts against the same usage limits." A heavy morning in the claude.ai app eats directly into your Claude Code window.
This card sorts cause from anomaly — it deliberately doesn't read your quota, because Claude Code exposes no real-time quota number (#13585). Measure your real consumption for free with ccusage and read the full why-am-I-hitting-limits explainer. To make the quota you do have go much further, the Token & Cost Survival Guide ($19) has the 13 cost-spike patterns and the per-run token-reduction playbook (cache hygiene, model routing, context trimming).
