What it does

Dynamo Dotnet Expert is an agent skill from DynamoDS/Dynamo. Write and review C/.NET code in Dynamo following Dynamo coding standards, modern C patterns, and repo conventions. Use this skill whenever writing C code, reviewing a PR diff, designing types, managing PublicAPI surface files, choosing patterns, making performance decisions, or refactoring in the Dynamo codebase. Also use when asking about NUnit testing, async patterns, error handling, immutability, or security in Dynamo.

Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files and assets (for example `assets/csharp-patterns.md`, `assets/publicapi-guide.md` and `references/quality-checklist.md`).

It sits in Development, covering Code quality and Refactoring. It works with .NET and C#. The repository describes itself as: Open Source Graphical Programming for Computational Design and Automation. The licence is Apache-2.0.

When your agent uses it

  • Reviewing a PR diff
  • Designing types
  • Managing PublicAPI surface files
  • Choosing patterns

Example prompts

  • “/dynamo-dotnet-expert”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Read before suggesting — read the relevant file(s) before proposing changes.
  2. Repo conventions win — when repo standards conflict with generic .NET advice, follow the repo.
  3. Check public API impact — any new public member needs a PublicAPI.Unshipped.txt entry.
  4. Run quality checks — before finishing, verify against the quality checklist.

What it can do on your machine

Read from SKILL.md and the folder at commit 8cadc02. 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

    Shell commands in SKILL.md call:

    • dotnet

    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

Dynamo Dotnet Expert loads about 909 tokens when it runs, and up to ~1.3k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 334 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~112
When it runs · the whole SKILL.md, loaded when a task matches
~909
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.3k

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

Also use when asking about NUnit testing, async patterns, error handling, immutability, or security in Dynamo.

Dynamo dotNet Expert

When to use

  • Writing or reviewing C#/.NET code in Dynamo.
  • Designing public APIs, choosing types, or making performance decisions.
  • Managing PublicAPI surface files.
  • Refactoring for modern C# patterns.
  • WPF/UI work in DynamoCoreWpf.

When not to use

  • Writing NUnit tests -- use dynamo-unit-testing instead.
  • Architecture / onboarding questions -- use dynamo-onboarding instead.
  • PR descriptions -- use dynamo-pr-description instead.

Inputs expected

A C# file or diff to review, a feature requirement, or a question about .NET patterns in the Dynamo codebase.

Output format

Code suggestions with explanations, or a review with specific file/line references.

Workflow

  1. Read before suggesting — read the relevant file(s) before proposing changes.
  2. Repo conventions win — when repo standards conflict with generic .NET advice, follow the repo.
  3. Check public API impact — any new public member needs a PublicAPI.Unshipped.txt entry.
  4. Run quality checks — before finishing, verify against the quality checklist.

Quick Decision Guide

SituationAction
Adding a public memberUpdate PublicAPI.Unshipped.txt — see publicapi-guide.md

Project Conventions

Naming
  • PascalCase for public members, classes, methods.
  • camelCase for private fields and local variables.
  • Prefix private fields with underscore only if the file already does so consistently.
  • XML documentation required on all public methods and properties.
Comments

Comments explain why, not what.
