codingbuddy nestjs.instructions.md

A set of instructions for reviewing NestJS MCP servers, including modules, tool handlers, resources, and dependency injection. NestJS is a framework for building structured Node.js applications; dependency injection supplies services to the code that needs them.

In plain words
What is it for?
It is for reviewing NestJS MCP server code, including module boundaries, injectable services, tool input validation, resource URI formats, error codes, and providers.
Why use it?
It helps keep server modules organized and ensures inputs, resource addresses, errors, and service dependencies follow the expected conventions.

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.

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

codingbuddy nestjs.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 2d 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

NestJS MCP Server Code Review

Module Structure

  • Each module should be self-contained with its own providers and exports
  • Use forwardRef only when absolutely necessary for circular dependencies
  • Services should be injectable and follow single responsibility

MCP Protocol

  • Tool handlers must validate input parameters
  • Resource URIs must follow the rules:// scheme convention
  • Error responses must use proper MCP error codes

Dependency Injection

  • Prefer constructor injection over property injection
  • Use custom providers (useFactory, useValue) appropriately
  • Avoid service locator pattern
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.
