Cost & usage report

Read references/mcp.md first for the tool contract and limits. This skill uses only metadata tools — no trace content, so no injection surface. If that file isn't present (this skill was lifted out on its own), ask the user for the plugin's references/mcp.md, or fall back to the hard rules: every tool is read-only, and get_cost_breakdown / get_usage_summary are the only tools this skill needs.

Turn the platform's cost and usage data into a short, decision-ready report.

Workflow

1. Scope. Confirm the date range (get_cost_breakdown takes start_date / end_date) and what the user cares about — total spend, a suspected spike, model mix, or quota headroom. Default to the last 7 days if unspecified.
