An end-to-end workflow for moving databases and data to Snowflake, a cloud data platform. It connects to the source, converts database code, and validates the resulting Snowflake tables.

It helps migrate supported database workloads to Snowflake and compare source and target table results during validation.

A database move involves more than copying tables: code conversion and result checking are also needed. This workflow keeps those migration and validation steps together.

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	$0.00065	$0.04053
Opus 5	$0.00032	$0.02027
Sonnet 5	$0.00013	$0.00811
Haiku 4.5	$0.00006	$0.00405

Security

Grade A, and why

migration 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.

The scan reads SKILL.md. This mod also ships 31 executable files (assessment/etl-assessment/scripts/__init__.py, assessment/etl-assessment/scripts/dag_renderer/__init__.py, assessment/etl-assessment/scripts/dag_renderer/render_dags.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Database Migration to Snowflake

Tell the user:

Welcome to Snowflake AIM for Data Warehouses.

On the first message of a session, the plugin injects whether a migration project exists in this directory. If the user's message already states what they want, act on it (Step 1); otherwise begin with Step 0. Either way, do not call migration_status — configure returns the status.

IMPORTANT NOTE

The built-in MCP server has a state machine that will guide you through user flows and ask you to "tell the user x" or "ask the user y". This is expected and you should follow its lead, as it is the official MCP server of Snowflake migrations.

Step 0: Ask first (no tools)

If the user's first message already states what they want (a specific task, or "continue"/"resume"), skip to Step 1. Otherwise greet and ask:

"What would you like to do? You can:

Continue — I'll pick up your migration where we left off

Something specific — tell me what you need"

When the injected context says this directory has no project yet, option 1 is Start a new migration instead.

Continue (or "start", "continue", "next", "resume", "keep going") → Step 1.
Specific request → Skill Match (no forced configure).

Step 1: Configure — one call, returns status

Call configure with project_dir = "<current directory>". Because this call is what sets project_dir for the session, the response contains both the restored session config and a ## Migration status block — the same JSON migration_status(mode="summary") returns (project_exists, directory_empty, by_type, stage_totals, routing, highest_stage_reached). Route from that block; do not make a separate migration_status call. Later configure calls that re-pass the same project_dir do not repeat the block; use migration_status(mode="summary") when you need a fresh read.

Step 1.A: If `project_exists` is false, there is no migration project in this directory.

What ships with it

60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

migration 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 65 tokens to every session and 4,053 once invoked, about $0.0003 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.
