What is netrock CLAUDE.md?

Project guidance for NETrock, a .NET web API with a SvelteKit web interface, PostgreSQL database, and MinIO file storage. It defines coding rules for the backend, frontend, and shared changes.

Use it when changing the API, frontend, data access, error handling, time handling, documentation, or package versions in NETrock.

It gives coding agents the project’s rules in one place, reducing inconsistent implementations and API changes that could break other clients.

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	$0.02492	$0.02492
Opus 5.5	$0.00997	$0.00997
Sonnet 5.5	$0.00498	$0.00498
Haiku 4.5	$0.00249	$0.00249

Security

Grade A, and why

netrock CLAUDE.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.

CLAUDE.md

NETrock - .NET 10 API (Clean Architecture) + SvelteKit frontend (Svelte 5), fully dockerized.

The backend API is the core of the project. It is a public-facing API designed to serve any client - multiple frontends, mobile apps, other backends, third-party integrations. The SvelteKit frontend is a fully functional reference client, not a throwaway. Treat every API change as if unknown consumers depend on it.

Frontend (SvelteKit :5173) → /api/* proxy → Backend API (.NET :8080) → PostgreSQL / MinIO
Backend layers: WebApi → Application ← Infrastructure → Domain + Shared

Hard Rules

Backend

Result/Result<T> for all fallible operations - never throw for business logic
TimeProvider (injected) - never DateTime.UtcNow or DateTimeOffset.UtcNow
C# 13 extension(T) syntax for new extension methods
Never null! - fix the design instead
ProblemDetails (RFC 9457) for all error responses - never anonymous objects or raw strings
internal on all Infrastructure service implementations
/// <summary> XML docs on all public and internal API surface
System.Text.Json only - never Newtonsoft.Json
NuGet versions in Directory.Packages.props only - never in .csproj

Frontend

Never hand-edit v1.d.ts - run pnpm run api:generate
Svelte 5 Runes only - never export let
interface Props + $props() - never $props<{...}>()
Logical CSS only: ms-*/me-*/ps-*/pe-* - never ml-*/mr-*/pl-*/pr-*
No any - define proper interfaces
Feature folders in $lib/components/{feature}/ with barrel index.ts
Use shadcn-svelte components (pnpm dlx shadcn-svelte@latest add <name>) - never build what shadcn already provides
Pixel-perfect responsiveness - mobile, tablet, desktop, ultrawide, landscape and portrait
Touch targets minimum 44px on all interactive elements
Unified UX - reuse existing components and patterns so the app feels like one product, not five
No overflow - dialogs, modals, and pages must never show scrollbars. Fit content to viewport.

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.
