What is reproductions?

A set of rules for building small, repeatable examples that demonstrate a software problem. It covers source-code and documentation research, testing, security, and explanation.

Use it to investigate an issue, study its implementation, create a minimal reproduction, verify the behavior, and document the result.

It gives developers a complete process for turning a reported issue into a runnable example and a documented solution or workaround.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/sfc-gh-cconner/support-rules-mcp

Made for: Cursor.

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	$0.00598	$0.00598
Opus 5	$0.00299	$0.00299
Sonnet 5	$0.00120	$0.00120
Haiku 4.5	$0.00060	$0.00060

Measured 8d ago against content hash 6aae041535e3, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

reproductions 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.

Reproduction Building - Complete Ruleset

PURPOSE: Complete workflow for creating minimal, parameterized reproductions with proper documentation, security, and template standards.

Meta-Rule: This combines core Snowflake knowledge, code quality guidance, and reproduction patterns.

📦 Included Rules

This meta-rule includes:

✅ Core: Source code access (GitHub MCP)
✅ Core: Documentation access (Snowflake Docs MCP)
✅ Core: Code quality & examples (Context7 MCP)
✅ Workflow: Reproduction building guide

@include core/01-github-mcp.mdc @include core/02-docs-mcp.mdc @include core/03-code-quality-mcp.mdc @include workflows/reproductions.mdc

🎯 Quick Reference

Reproduction Flow

Understand Issue → Gather details and expected behavior
Study Implementation → Find source code
Get Examples → Context7 for usage patterns
Build Minimal Repro → Self-contained, runnable code
Verify Behavior → Test thoroughly
Document → Complete explanation
Provide Fix/Workaround → Solution or temporary fix

Key Principles

Keep it minimal and focused
Make it self-contained and runnable
Use environment variables for credentials
Include clear documentation
Provide workarounds when possible
Reference source code explicitly

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.

reproductions is a cursor rule published in the GitHub repository sfc-gh-cconner/support-rules-mcp (0 stars, last pushed 11mo ago), licensed Apache-2.0. It adds 598 tokens to every session, about $0.0030 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.
