Use when reviewing BigQuery spend, query failure patterns, or scan inefficiencies -- identifying which jobs, users, or projects drive cost, or preparing optimization recommendations for a cost review.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# BigQuery Cost Audit ## When to Use - Reviewing BigQuery query costs, failure patterns, or performance inefficiencies. - Identifying which jobs, users, or projects are driving the highest spend. - Preparing optimization recommendations for an engineering or cost-review meeting. - Auditing governance: scheduled jobs, duplicated logic, or low-value recurring queries. ## Goals - Identify the main cost drivers by job, project, and user. - Detect repeated waste patterns (full scans, failed retries, duplicated logic). - Suggest realistic optimizations with estimated impact. - Translate technical waste into business-language findings. ## What to Inspect ### Cost hotspots ```sql -- Top 20 most expensive jobs in the past 7 days SELECT job_id, user_email, query, total_bytes_processed / POW(1024, 4) AS tb_processed, ROUND(total_bytes_processed / POW(1024, 4) * 6.25, 2) AS estimated_cost_usd, creation_time FROM `region-us`.INFORMATION_SCHEMA.JOBS WHERE creation_time > TIMESTAMP_SUB(CURRENT_TIMESTAMP(), INTERVAL 7 DAY) AND job_type = 'QUERY' AND state = 'DONE' ORDER BY total_bytes_processed DESC LIMIT 20; ``` ### Repeated failures ```sql SELECT …

How to install
mdr add yeaight7/agent-powerups/bigquery-cost-audit@sha256:fa001115a97320c6The line at the top of this page pins the label git:20260605.e56fe2c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
