check-prereq-agent-dotnet

check-prereq-agent-dotnet is a skill for Claude Code from diagrid-labs/dapr-skills. It costs 60 tokens per session (876 once invoked), scanned A, original, MIT.

A checklist tool for preparing a .NET environment to build durable AI agents—programs that can use language models and tools while reliably continuing after interruptions—with Microsoft Agent Framework and Dapr Workflow.

In plain words
What is it for?
Use it to verify the computer and model-provider setup for .NET agents before creating one.
Why use it?
It finds missing software or services before you start building, such as the .NET SDK, containers, Dapr, a C# language server, or access to an AI model.

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

check-prereq-agent-dotnet scanned grade A with 1 finding 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 12d 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.

Check Prerequisites for .NET Agents

Overview

This skill checks whether all prerequisites are installed for building durable AI agents in .NET. Run this skill before using the create-agent-dotnet skill.

On naming. Dapr Agents is a Python-only framework; there is no Dapr Agents SDK for .NET. The .NET path is Microsoft Agent Framework (Microsoft.Agents.AI, Microsoft.Extensions.AI) executed durably on Dapr Workflow by the Diagrid.AI.Microsoft.AgentFramework package. Every agent turn — each LLM call and each tool call — becomes a workflow activity, which is where the durability comes from. The Dapr in the .NET type names (AddDaprAgents, IDaprAgentInvoker) refers to that workflow runtime, not to the Python framework.

Prerequisites

The following must be installed:

Prerequisite Checks

Run ALL of these checks. Check steps 2–6 in parallel. Track which checks pass and which fail.

Step 1: Detect Operating System

Read the file at ../shared/prereq-detect-os.md and follow those instructions.

Step 2: Check the C# LSP plugin

Read the file at ../shared/prereq-check-csharp-lsp.md and follow those instructions.

Step 3: Check .NET SDK version

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.
