go-grpc-service-rule

go-grpc-service-rule is a cursor rule for Cursor from toptalentcoder/Cursor-AwesomeRules. It costs 123 tokens per session, scanned A, a copy of go-grpc-service-rule, CC0-1.0.

Go guidelines for implementing gRPC services, where programs communicate through generated interfaces and structured messages.

In plain words
What is it for?
Use them to build gRPC servers in Go from Protocol Buffer definitions and connect those services to databases.
Why use it?
They provide a consistent approach to defining services, generating code, validating requests, accessing databases, and avoiding unsafe queries.

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

go-grpc-service-rule 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 5d 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.

Origin

This is a copy

100% identical to go-grpc-service-rule — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

When working with gRPC services in Go:

  • Define your Protocol Buffer messages and service.
  • Generate Go code from the Proto file using protoc.
  • Implement the gRPC server in Go, handling requests and responses.
  • Connect to databases using Go's database/sql package or an ORM.
  • Handle errors properly and implement proper validation.
  • Consider using an ORM like GORM for more complex database interactions.
  • Follow best practices for security, such as using prepared statements to prevent SQL injection.
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.
