What is snowflake-architecture-diagram?

A skill for creating, viewing, and exporting Snowflake architecture diagrams. Snowflake is a cloud data platform for storing, processing, and analyzing data.

Use it to design or refine diagrams for data warehouses, streaming systems, Internet-of-Things pipelines, security, machine learning, customer data, governance, or existing table lineage.

It turns data pipelines, services, and their connections into diagrams that can be inspected locally and shared in common image or diagram formats.

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	$0.00109	$0.02070
Opus 5.5	$0.00044	$0.00828
Sonnet 5.5	$0.00022	$0.00414
Haiku 4.5	$0.00011	$0.00207

Security

Grade A, and why

snowflake-architecture-diagram scanned grade A with 1 finding 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 2mo ago.

The scan reads SKILL.md. This mod also ships 27 executable files (assets/composer/__init__.py, assets/composer/build_rich_states.py, assets/composer/composer.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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Optionally probe `localhost:3002` and `localhost:8082` (curl with 1s timeout) to detect `CONNECTED_UI_READY`.

Snowflake Architecture Diagram

Generate professional Snowflake architecture diagrams with one of four modes. The skill auto-detects what is available and routes to the right sub-skill. Output is always exportable (Mermaid source, SVG, PNG) and renders in a self-contained viewer that runs locally.

When to load

Trigger this skill when the user wants to:

Create a Snowflake architecture diagram (medallion, streaming, IoT, security, ML, customer 360, governance, etc.)
Visualize a real data pipeline (from lineage of an existing table)
Export a diagram for slides, docs, or sharing
Refine or iterate on a previously generated diagram

Prerequisites

Mode	Requires
`standalone`	Python 3 + a modern browser. No Snowflake connection needed.
`connected-cli`	Active `cortex` connection + `SNOWGRAM_AGENT` deployed
`connected-ui`	Connected-CLI prerequisites + frontend at `localhost:3002` + backend at `localhost:8082`
`from-lineage`	Active `cortex` connection with lineage access (any account)
`bootstrap`	Active connection with privileges to deploy SnowGram into a target DB

Path resolution (READ THIS FIRST)

All sub-skills reference assets via $SKILL_DIR/... (bash) or SKILL_DIR/... (Python). Resolve these once at the top of any workflow:

# Bash — source the canonical resolver, then use $SKILL_DIR / $VIEWER_DIR / etc.
source "<absolute path to assets/scripts/skill_paths.sh>"
echo "$SKILL_DIR"   # absolute path to the skill root

# Python — import skill_paths from assets/scripts/
import sys, importlib.util
spec = importlib.util.spec_from_file_location(
    "skill_paths",
    "<absolute path to assets/scripts/skill_paths.py>",
)
sp = importlib.util.module_from_spec(spec); spec.loader.exec_module(sp)
TEMPLATES_DIR = sp.TEMPLATES_DIR  # etc.

Where to find the absolute path of assets/scripts/skill_paths.sh:

The skill loader's preamble shows Base directory for this skill: <PATH>. Take that path and append /assets/scripts/skill_paths.sh.
Or call cortex skill list and find the snowflake-architecture-diagram: line.

Files

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.

snowflake-architecture-diagram is a skill published in the GitHub repository sfc-gh-abannerjee/SnowGram (2 stars, last pushed 1mo ago), licensed MIT. It adds 109 tokens to every session and 2,070 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
