What is data-validation-setup?

A one-time setup workflow for the service used to validate migrated data between supported source databases and Snowflake. Snowflake is a cloud database, and the workflow checks that its validation service is ready.

It is for preparing the cloud service, compute resources, and worker configuration for source-to-Snowflake data validation.

It removes the infrastructure setup work needed before data-validation jobs can run.

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	$0.00027	$0.00935
Opus 5	$0.00014	$0.00467
Sonnet 5	$0.00005	$0.00187

Security

Grade A, and why

data-validation-setup 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cloud Data Validation Setup

One-time infrastructure setup for validating migrated data between a source database and Snowflake using the Cloud Data Validation feature via the scai CLI.

Supported sources: SQL Server, Redshift, Oracle, Teradata, PostgreSQL, Snowflake Supported target: Snowflake

Prerequisite

Load ../../data-infrastructure/SKILL.md first. It handles shared prerequisites, compute pool registration, and worker config (source host/port/credentials, source database, source schema). Return here after it completes.

For migration-source projects, validation requires target tables to already be deployed to Snowflake. For Snowflake-to-Snowflake validation, the source and target objects must already exist; do not run deployment or data migration first.

Step 1: Verify Orchestrator Service

After the shared infrastructure step has registered the compute pool, confirm the orchestrator service started:

SELECT SYSTEM$GET_SERVICE_STATUS('SNOWCONVERT_AI.DATA_MIGRATION.DATA_MIGRATION_SERVICE');

If it returns [] (suspended/not started), resume it manually:

ALTER SERVICE SNOWCONVERT_AI.DATA_MIGRATION.DATA_MIGRATION_SERVICE RESUME;

Wait 30-60s and re-check until status shows READY.

This completes infrastructure setup. The actual validation is started later by the validate-objects skill via:

progress_setup(mode="data_validation") — choose full vs incremental (+ sync strategy).
validate_data(mode="setup", where=..., validation_type=..., sync_strategy=...) — generates artifacts/data_validation/workflows/<hash>.yaml and patches known toggles / sync strategy.
data_infrastructure(mode="up") — bring the shared orchestrator + worker up once. Snowflake-source projects bring up only the orchestrator (start_worker=false).
Agent edits (e.g. watermarkColumn, partition columns) then validate_data(mode="run", workflow_path=...) — pure dispatch (scai data validate create-workflow) against the already-running infrastructure.

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.
