data-query

data-query is a cursor rule for Cursor from rajitsaha/100xprism. It costs 34 tokens per session (407 once invoked), scanned A, original, MIT.

A tool that turns a plain-English business question into a database query, runs it, and explains the result.

In plain words
What is it for?
Use it to analyze data in BigQuery, PostgreSQL, MySQL, SQLite, or another database with a command-line interface.
Why use it?
It removes the need to write SQL by hand for routine analysis, while still showing the query and key numbers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

data-query scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Suggested model tier: balanced (moderate reasoning)

Query — Plain-English Database Analytics

Describe what you want to know — Claude writes and runs the query.

How to use

  • /query <business question> — Claude translates to SQL, runs it, returns analysis

Supported interfaces

  • BigQuery: bq CLI — bq query, bq show, bq ls
  • PostgreSQL: psql CLI
  • MySQL: mysql CLI
  • SQLite: sqlite3 CLI

Phase 1 — Understand the question

Restate the business question in concrete terms. If the schema is ambiguous, inspect it first:

# BigQuery — show table schema
bq show <dataset>.<table>

# PostgreSQL
PGPASSWORD="$DB_PASS" psql -h "$DB_HOST" -U "$DB_USER" -d "$DB_NAME" \
  -c "\d <table_name>"

Phase 2 — Write and run the query

Write the SQL for the business question. Run it using the appropriate CLI. Explain the results in plain English.


Phase 3 — Return results

Return:

  1. The SQL written
  2. A plain-English answer to the original question
  3. A table of key numbers

For recurring queries: offer to save as a named script.

Scope vs /db

  • /query = analytics in plain English (you describe a business question)
  • /db = execute specific SQL against a named connection (you write the SQL or say "migrate")
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
