What is snowflake-to-bigquery-converter?

A converter and audit workflow for LookML projects, which are files that define data models and reports in Looker, when moving SQL from Snowflake to Google BigQuery.

Use it to inspect LookML for Snowflake syntax and apply or review conversions for BigQuery.

It identifies Snowflake-specific SQL and suggests equivalent BigQuery Standard SQL, reducing manual edits and missed dialect differences during a migration. It requires the Looker command-line tool and an authenticated Looker account.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00083	$0.01772
Opus 5.5	$0.00033	$0.00709
Sonnet 5.5	$0.00017	$0.00354
Haiku 4.5	$0.00008	$0.00177

Security

Grade A, and why

snowflake-to-bigquery-converter 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 18d 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.

Snowflake to BigQuery Converter Skill

This skill audits LookML files for Snowflake-specific SQL syntax and proposes BigQuery Standard SQL equivalents, checking them against a bundled syntax transition reference guide using the Looker CLI (looker-cli).

Workflow Instructions

When invoked, execute the following steps precisely:

Pre-flight Guardrails & Verification: Before requesting details or fetching code, verify that looker-cli is installed and authenticated:
- Verify CLI Installation: Run: looker-cli --help If the command fails or is not found: Halt immediately and instruct the user:
  
  "looker-cli is not installed or not in your PATH. Please refer to the installation instructions in the Looker CLI documentation: https://github.com/looker-open-source/looker-cli"
- Verify Authentication & Looker Configuration: Run: looker-cli user me If unauthenticated or connection fails: Halt immediately and instruct the user:
  "You are not authenticated to a Looker instance. Please configure and authenticate looker-cli using one of the following methods:
  
  Method 1: Interactive OAuth (Recommended)
  1. In Looker, ensure the Looker CLI connector is enabled: Navigate to Admin > Platform > BI Connectors > under Developer Tools, toggle Looker CLI to ON.
  2. Configure your profile and log in:
```
looker-cli profile add default --host <your-looker-host> --port 443
looker-cli profile use default
looker-cli session login --oauth
```
  Method 2: API Keys (Client ID & Client Secret) If OAuth is not enabled or for headless/service accounts:
```
looker-cli profile add default --host <your-looker-host> --port 443 --client-id <CLIENT_ID> --client-secret <CLIENT_SECRET>
looker-cli profile use default
```
  Once configured, please rerun your migration request."

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.
