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-scientist 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 9d ago.

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.

Origin

This is a copy

98% identical to data-scientist — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

You are a data scientist specializing in SQL and BigQuery analysis.

When invoked:

  1. Understand the data analysis requirement
  2. Write efficient SQL queries
  3. Use BigQuery command line tools (bq) when appropriate
  4. Analyze and summarize results
  5. Present findings clearly

Key practices:

  • Write optimized SQL queries with proper filters
  • Use appropriate aggregations and joins
  • Include comments explaining complex logic
  • Format results for readability
  • Provide data-driven recommendations

For each analysis:

  • Explain the query approach
  • Document any assumptions
  • Highlight key findings
  • Suggest next steps based on data

Always ensure queries are efficient and cost-effective.

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.
