snowflake-architecture-diagram-standalone

snowflake-architecture-diagram-standalone is a skill for Claude Code, Codex from sfc-gh-abannerjee/SnowGram. It costs 66 tokens per session (2,419 once invoked), scanned A, original, MIT.

A skill for creating Snowflake data architecture diagrams without connecting to a Snowflake account. Snowflake is a cloud data platform, and the skill can compose a diagram from the request or adapt one of 14 known reference designs when the match is clear.

In plain words
What is it for?
Use it to draft diagrams for data platforms such as a bronze/silver/gold lakehouse, or other Snowflake architectures described in a prompt.
Why use it?
It lets someone create an exportable architecture diagram before a Snowflake connection is available. Its rules also keep reference templates from replacing prompt-specific design work.

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.

Security

Grade A, and why

snowflake-architecture-diagram-standalone 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 8d 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 — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Standalone mode

Generate exportable Snowflake architecture diagrams without needing a deployed SnowGram agent or any Snowflake connection. The default path composes a fresh diagram from flow_builder informed by cortex search docs and Snowflake-expert SME skills. The 14 bundled reference-architecture templates serve as fallbacks for prompts that cleanly match a known pattern (e.g. "medallion lakehouse with bronze/silver/gold").

Design rule (enforced by the rule store):

Templates are FALLBACKS, not the default generation path. Generate from-scratch (rich-state authoring) when the prompt does not closely match a known template pattern. Only fall back to a template when the prompt's intent maps cleanly onto one of the 14 reference architectures, AND in that case still apply prompt-driven customizations rather than emitting the template verbatim.

Path resolution (do this once)

This sub-skill uses $SKILL_DIR/... paths. Resolve them by sourcing the canonical helper:

source "<SKILL_BASE_DIR>/assets/scripts/skill_paths.sh"
# Sets $SKILL_DIR, $TEMPLATES_DIR, $COMPOSER_DIR, $VIEWER_DIR, $SCRIPTS_DIR, $STATE_FILE.

For Python helpers, import assets/scripts/skill_paths.py analogously. The parent SKILL.md shows the importlib pattern.

Workflow

Step 1 — Gather domain knowledge (PRIMARY, not optional)

Quality of the rendered diagram depends on having current Snowflake best-practice context BEFORE composition. Skip this step ONLY for trivial / one-off requests; for any production-quality diagram, do all three sub-steps.

1a. Detect pipeline type
PIPELINE_TYPE=$(python3 "$COMPOSER_DIR/intent_router.py" --detect-type "<user prompt>" | python3 -c "import sys,json;print(json.load(sys.stdin)['pipeline_type'])")

PIPELINE_TYPE is one of: medallion | streaming | iot | batch | security | generic.

1b. Run targeted documentation queries
python3 "$COMPOSER_DIR/intent_router.py" --queries-for "$PIPELINE_TYPE"
# → 3 queries to feed cortex search docs

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-standalone is a skill published in the GitHub repository sfc-gh-abannerjee/SnowGram (2 stars, last pushed 2mo ago), licensed MIT. It adds 66 tokens to every session and 2,419 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 2026-08-31.
