claude-context

Report the current session's resource facts — context-window occupancy, 5-hour and 7-day subscription usage, session cost, and compaction count — as pure measurements with provenance (human summary + machine-readable JSON block). Use when you or the user want to know how much context, quota, or cost the session has used — and, for agents and subagents, to gate your own behavior on those numbers: checkpoint or stop as context fills up (before Claude Code's auto-compaction silently drops CLAUDE.md guidance or recent instructions), or pause before exhausting the 5h/7d limit. Reports facts only; your instructions set the policy. Makes no recommendations.
