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

genocs-library copilot-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 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.

What it actually says

Copilot Instructions

1. Coding Standards

  • Follow standard C# conventions.
  • Comments: Strictly "Why" not "What." Do not explain syntax; explain business context and architectural decisions.
  • Self-Documenting Code: Prioritize meaningful variable/method names over comments.

2. Tech Stack & Architecture

Backend (C# .NET)

  • DI Container: Microsoft.Extensions.DependencyInjection.
  • Data Access:
    • MongoDB Connectors: Specifically for MongoDB interactions.
    • Repository Pattern: Implemented for data access abstraction.
  • Validation: FluentValidation.
  • Testing: xUnit, Reqnroll.

Infrastructure

  • DB: MongoDB or SQL Server (depending on the use case).
  • Caching: Redis.
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.
