query

name	query
description	Runs a direct SQL query against any BigQuery table and returns results as a formatted table. Use when the question requires counts, aggregations, rankings, or distributions — not when it requires reading document text. Use {project} in the SQL as a placeholder for the GCP project name.

Query Skill

Runs a direct SQL query against BigQuery and prints results as a formatted text table. No embedding required.

Usage

python ${CLAUDE_PLUGIN_ROOT}/skills/query/scripts/query.py \
  --sql "<SQL query using {project} as project placeholder>"

The script replaces {project} with the active GCP project at runtime.

When to use

Use this skill instead of embed + vector-search when the question requires:

• Counts ("how many tickets about X?")
• Rankings ("top N topics by volume")
• Distributions ("ticket count by product")
• Aggregations ("average sentiment by category")
• Any answer that is a number, ranked list, or summary statistic

Use embed + vector-search when the question requires reading and synthesizing document text.

Common SQL patterns

Dataset: {project}.customer_experience_derived Tables: kitsune_retrieval_index, zendesk_retrieval_index, knowledge_base_retrieval_index

Date filter columns:

• Kitsune: creation_date DATE — use creation_date BETWEEN 'YYYY-MM-DD' AND 'YYYY-MM-DD'
• Zendesk: creation_date TIMESTAMP — use DATE(creation_date) BETWEEN 'YYYY-MM-DD' AND 'YYYY-MM-DD'
• Knowledge Base: no date column

-- Top topics by volume (Kitsune)
SELECT topic, COUNT(*) AS count
FROM `{project}.customer_experience_derived.kitsune_retrieval_index`
WHERE creation_date BETWEEN '2026-03-24' AND '2026-04-22'
GROUP BY topic ORDER BY count DESC LIMIT 10

-- Top categories by volume (Zendesk)
SELECT category_generated, COUNT(*) AS count
FROM `{project}.customer_experience_derived.zendesk_retrieval_index`
WHERE DATE(creation_date) BETWEEN '2026-03-24' AND '2026-04-22'
GROUP BY category_generated ORDER BY count DESC LIMIT 10

-- Average sentiment by topic (Kitsune only — do not use Zendesk sentiment)
SELECT topic, COUNT(*) AS count, ROUND(AVG(sentiment_score), 2) AS avg_sentiment
FROM `{project}.customer_experience_derived.kitsune_retrieval_index`
WHERE creation_date BETWEEN '2026-03-24' AND '2026-04-22'
GROUP BY topic ORDER BY avg_sentiment ASC LIMIT 10

-- Volume by product (Zendesk)
SELECT product, COUNT(*) AS count
FROM `{project}.customer_experience_derived.zendesk_retrieval_index`
WHERE DATE(creation_date) BETWEEN '2026-03-24' AND '2026-04-22'
GROUP BY product ORDER BY count DESC

Output

A plain-text formatted table:

topic          count
-------------  -----
site-breakage  142
sync           98
passwords      74

Troubleshooting

Symptom	Fix
Authentication rejected (401)	Run gcloud auth application-default login
No GCP project configured	Run gcloud config set project <project-id>
API error	Confirm the project name with DE and re-authenticate
No results	Check date range, table name, and filter values
