nodejs

nodejs is a cursor rule for Cursor from sfc-gh-cconner/support-rules-mcp. It costs 1,611 tokens per session, scanned A, original, Apache-2.0.

A set of rules for investigating the Node.js connector for Snowflake applications. Node.js is a runtime for executing JavaScript outside a web browser.

In plain words
What is it for?
Use it when troubleshooting Snowflake connections in JavaScript or TypeScript, including OAuth, key-pair authentication, and connection pools.
Why use it?
It provides specific search patterns for understanding connection setup, authentication, and connection pooling in the connector's source code.

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

nodejs 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 1mo 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.
