What is assess-sas-migration?

An analysis tool that measures the size and complexity of a collection of SAS programs before migration to Snowflake. It produces dependency diagrams, complexity groupings, and an order for migration waves.

Use it to assess .sas files, classify conversion difficulty, map which programs depend on others, and optionally prepare an effort and staffing plan.

It helps teams understand scope and dependencies before converting code, so they can decide what to migrate first.

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.

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	$0.00093	$0.03248
Opus 5	$0.00046	$0.01624
Sonnet 5	$0.00019	$0.00650
Haiku 4.5	$0.00009	$0.00325

Security

Grade A, and why

assess-sas-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 12 executable files (tool/assess_sas.py, tool/emit_cur.py, tool/sas_analyzer/__init__.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.

Assess SAS Migration

© Snowflake Inc. This skill and its contents are the proprietary intellectual property of Snowflake Inc.

Analysis-only tool for assessing SAS-to-Snowflake migration complexity, volume, and sequencing.

Purpose: Pre-conversion assessment that informs the convert-sas-to-snowflake skill with portfolio-level insights, per-file tier classification, and a migration wave plan.

Output: A merged assessment report (assessment_complete.md) covering executive summary, CLI quantitative detail, dependency DAG, complexity analysis, a migration wave plan, open questions & dependencies, and recommendations — backed by the CLI's JSON/Markdown/Mermaid artifacts. On request, a separate effort_staffing_plan.md adds effort + staffing and embeds the same wave plan.

Two analysis layers:

Python CLI (default, quantitative): parses, scores, classifies, builds the DAG. Fast and deterministic.
CoCo-native (additive, qualitative): the skill reads the .sas files directly to explain areas of complexity — themes, construct hotspots, and risks — on top of the CLI numbers. If the CLI cannot run (no Python, or user opts out), this layer runs standalone using the heuristics in references/complexity-analysis.md.

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.
