nestjs-starter: Instructions file for GitHub Copilot

.github/instructions/services.instructions.md

nestjs-starter services.instructions.md is an instructions file for GitHub Copilot from hmake98/nestjs-starter. It costs 151 tokens per session, scanned A, original, MIT.

A set of coding rules for services in a NestJS starter project. NestJS is a framework for building server applications, while Prisma is a database toolkit and Redis is an in-memory data store.

In plain words
What is it for?
Use it when adding service classes, checking whether records exist, handling errors, reading configuration, logging failures, and defining response objects.
Why use it?
It keeps service code consistent and avoids exposing database details, raw error messages, environment variables, or untyped database records.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is hmake98/nestjs-starter's own configuration. It tells GitHub Copilot how to work on nestjs-starter itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything nestjs-starter configures →

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

nestjs-starter services.instructions.md 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 2mo 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.

What it actually says

Service Conventions

  • Inject repositories, not DatabaseService directly.
  • Logger: private readonly logger = new Logger(ClassName.name). Only call this.logger.error(...) for unexpected 5xx failures.
  • Repeated existence checks: extract private async assertExists(id: string): Promise<void> using existsById.
  • All errors: throw new HttpException('domain.error.key', HttpStatus.STATUS) — always an i18n key string, never a raw message.
  • Config access: this.configService.getOrThrow<string>('domain.nested.key') — never process.env.
  • Return typed response DTOs, not raw Prisma entities.
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.
