.NET Crash Dump Collection

What it does

When your agent uses it

• Enabling automatic crash dumps for a CoreCLR or NativeAOT app
• Grabbing a dump from a running .NET process
• Setting up dump collection in a Docker or Kubernetes deployment

Example prompts

• “Enable automatic crash dumps for my NativeAOT service on Linux.”
• “Capture a dump from the running .NET process before it restarts.”
• “Configure dump collection for our .NET container in Kubernetes.”

Requirements

• A modern .NET application, either CoreCLR or NativeAOT
• dotnet-dump for collecting dumps from running processes

Workflow steps

3 steps, taken from the step headings in SKILL.md.

1. 1Identify the Scenario
2. 2Load the Appropriate Reference
3. 3Execute

What it can do on your machine

Read from SKILL.md and the folder at commit a660de8. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are bash and powershell).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

.NET Crash Dump Collection loads about 1.1k tokens when it runs, and up to ~6.9k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 369 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~111

When it runs · the whole SKILL.md, loaded when a task matches

~1.1k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~6.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

dump-collect

description

Configure and collect crash dumps for modern .NET applications. USE FOR: enabling automatic crash dumps for CoreCLR or NativeAOT, capturing dumps from running .NET processes, setting up dump collection in Docker or Kubernetes, using dotnet-dump collect or createdump. DO NOT USE FOR: analyzing or debugging dumps, post-mortem investigation with lldb/windbg/dotnet-dump analyze, profiling or tracing, or for .NET Framework processes.
