bq-optimize

bq-optimize is a command for coding agents from justvinhhere/bigquery-expert. It costs 21 tokens per session (333 once invoked), scanned A, original, Apache-2.0.

A command that rewrites a Google BigQuery SQL query to fix all detected patterns from the BigQuery optimization guide. You can provide a file path or paste the SQL directly.

In plain words
What is it for?
Use it to optimize a BigQuery SQL file or query, remove the guide's 11 listed anti-patterns, and receive the rewritten SQL with a change summary.
Why use it?
It applies a consistent review and rewrite process while aiming to preserve the original query's results. It also explains which patterns it changed.

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

bq-optimize 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 4d 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.

What it actually says

BigQuery SQL Optimize

Rewrite the provided BigQuery SQL with all detected anti-patterns fixed, using the bigquery-optimization skill.

Instructions

  1. Determine the SQL to optimize:

    • If a file path argument is provided, read that file.
    • If no argument is provided, look for the most recent BigQuery SQL in the current conversation.
    • If no SQL is found, ask the user to provide a query or file path.
  2. Detect all anti-patterns by running the full 11-pattern check.

  3. Apply all fixes to produce an optimized version of the query:

    • Preserve the original query semantics exactly -- the optimized query must return the same data.
    • Apply fixes in this order: SimpleSelectStar, SemiJoinWithoutAgg, DynamicPredicate, OrderByWithoutLimit, StringComparison, CTEsEvalMultipleTimes, LatestRecordWithAnalyticFun, JoinOrder, WhereOrder, MissingDropStatement, ConvertTableToTemp.
  4. Output the result:

## Optimized Query

(fully rewritten SQL)

## Changes Applied

1. **PatternName**: What was changed and why.
2. **PatternName**: What was changed and why.

## Summary
X anti-pattern(s) fixed. The optimized query preserves the original semantics.
  1. If no anti-patterns are found, return the original query and confirm it already follows best practices.

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.
