Install bigquery
Connect the hosted Costory MCP at https://app-api.costory.io/mcp and complete browser OAuth with a Costory workspace with billing data connected. Installing the skill folder alone does not configure that connection. Follow the publisher's setup for your agent, then install the selected skill below. Publisher setup instructions.
The skills CLI works with Claude Code, Codex, Cursor and other agents; the other routes copy the folder by hand.

How the author describes it
Use when the user asks about BigQuery costs, SKUs, on-demand Analysis vs capacity slots/editions, leftover on-demand, physical vs logical storage, time travel or fail-safe, streaming ingest, load/import jobs consuming a reservation, dbt or job labels, slot cost reallocation, dataset/table storage allocation, or unlabeled expensive queries. Call get_skill with skillId "bigquery" before investigating BigQuery spend or cloning the [BigQuery] dashboard. Not for GCP spend-based CUDs (recipes gcp-spend-cud).
From the description field of SKILL.md. Agents read this line to decide when to load the skill.
