What is data-infrastructure-teardown?

A shutdown workflow for the services that coordinate and run data migrations. It checks for active work, then stops local services or suspends Snowflake-hosted services and their compute resources.

Use it after a migration or validation cycle, or at the end of a migration, to stop the orchestrator and workers safely. It can also permanently remove the Snowflake worker service when requested.

Idle migration services can continue using paid compute or repeatedly waking a data warehouse. Shutting them down after a migration wave helps avoid those unnecessary costs.

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	$0.00073	$0.01784
Opus 5	$0.00036	$0.00892
Sonnet 5	$0.00015	$0.00357
Haiku 4.5	$0.00007	$0.00178

Security

Grade A, and why

data-infrastructure-teardown 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 — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Data Infrastructure Teardown

data_infrastructure(mode="down") does the teardown for both placements in one call:

Local — reaps the orchestrator + worker processes this MCP session started.
SPCS — when a compute_pool is configured for the project, it also suspends the SPCS orchestrator service and the Data Exchange Worker. The compute pool then auto-suspends on its own (AUTO_SUSPEND_SECS), so there is no separate pool step. Pass drop=true to remove the DEW service permanently instead of suspending it.

So teardown is normally just: call data_infrastructure(mode="down"). Everything below is the in-flight check to do first, plus the few cases the tool cannot cover on its own. Nothing auto-resumes — bring it back with data_infrastructure(mode="up") before the next wave (per ../SKILL.md).

Why this exists: an SPCS DATA_MIGRATION_SERVICE consumes compute pool seconds; a local orchestrator or local worker polling TASK_QUEUE wakes the warehouse on every interval — all accrue cost when idle.

When to Invoke

Trigger	Invocation
After `migrate_data()` reaches `completed` or `failed` for a wave	Caller prompts the user (default Yes) before loading this skill
After `validate_data()` reaches `completed` or `failed` for a wave	Caller prompts the user (default Yes) before loading this skill
End of full migration (no more waves)	Caller invokes this skill unconditionally

Skip entirely when the project never configured data infrastructure (no compute_pool and no local orchestrator/worker was started).

Step 1: Verify no in-flight workflows

data_infrastructure(mode="down") already refuses while a migrate/validate job it can see is running (it reads the project's relay ledger) — so a plain down is safe by default. But that ledger only covers jobs dispatched from this project on this machine. Before tearing down shared SPCS infrastructure that another machine might be using, confirm the queue is quiet directly:

data-infrastructure-teardown is a skill published in the GitHub repository sfc-gh-dflippo/snowflake-dbt-demo (33 stars, last pushed 3d ago), licensed Apache-2.0. It adds 73 tokens to every session and 1,784 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-10.
