Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00039 | $0.03157 |
| Opus 5 | $0.00019 | $0.01579 |
| Sonnet 5 | $0.00008 | $0.00631 |
| Haiku 4.5 | $0.00004 | $0.00316 |
Grade A, and why
sql-migration-waves-generator 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 — 288 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Migration Waves/Partition Generator
Overview
This skill produces a deployment wave plan for database/ETL migrations by running the SCAI CLI command scai assessment waves from inside a SCAI project. The command builds the dependency graph directly from the project's registry, assigns priority tiers, partitions objects into dependency-ordered waves, and emits a single consolidated JSON file.
Use this skill when:
- Planning SQL database and/or ETL migration deployment sequences
- Creating deployment waves that respect object dependencies
- Optimizing migration batch sizes for deployment
Sub-Agent Mode
When invoked from a parent skill (e.g., assessment/SKILL.md) as a sub-agent, the parent provides a context block with the fields below. Skip the prompts in Required User Interactions whenever the corresponding fields are present in the context block — sub-agents must not block on stdin.
| Field | Required | Notes |
|---|---|---|
project_dir |
yes | absolute path to the SCAI project root |
partition_min_size |
yes | integer; maps to --min-size |
partition_max_size |
yes | integer; maps to --max-size |
prioritization_globs |
yes | list of glob strings; emit one --prioritize <glob> per entry; pass nothing if empty |
wave_ordering |
yes | category (default) or dependency (adds --no-category-waves) |
output_dir |
yes | typically <project_dir>/assessment |
On entry: call the configure MCP tool with project_dir from the context block. Snowflake credentials are not required — scai assessment waves reads only the local registry.
Pass every required input as a CLI flag. If scai assessment waves still requests TTY input for any reason, fail fast and report the missing flag — do not block waiting for stdin.
On completion, return JSON only (no surrounding prose):
{
"sub_skill": "waves-generator",
"status": "ok",
"output_json": "<abs path to waves_analysis_*.json>",
"summary": "<one-line counts: partitions, sccs, objects>",
"error": null
}
What ships with it
5 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.
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.

sql-migration-waves-generator 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 39 tokens to every session and 3,157 once invoked, about $0.0002 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.
