dotnet-debugging

dotnet-debugging is a skill for Claude Code, Codex from novotnyllc/dotnet-artisan. It costs 131 tokens per session (2,159 once invoked), scanned A, original, MIT.

A debugging guide for Windows, Linux, and macOS applications, including native programs and .NET applications. It covers crash dumps, hangs, deadlocks, high CPU use, memory problems, and container diagnostics.

In plain words
What is it for?
Use it to inspect crash-dump files, attach to running processes, diagnose .NET memory and lock problems, investigate high CPU use, and troubleshoot applications in Docker or Kubernetes.
Why use it?
It gives developers structured ways to investigate failures that are difficult to reproduce or understand from application logs alone.

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

dotnet-debugging 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 4d 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.

dotnet-debugging

Overview

Windows and Linux/macOS debugging using WinDbg MCP tools (Windows), dotnet-dump, and lldb with SOS (Linux/macOS). Applicable to any application -- native, managed (.NET/CLR), or mixed-mode. Includes container diagnostic patterns for Docker and Kubernetes. Guides investigation of crash dumps, application hangs, high CPU, and memory pressure through structured command packs and report templates.

Platforms: Windows (WinDbg MCP, cdb), Linux/macOS (dotnet-dump, lldb with SOS, createdump, dotnet-monitor).

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.
