At a glance

Ensure that C types are documented with XML comments and follow best practices for documentation.

  • SKILL.md covers Guidance for all APIs, Methods, Constructors and Properties, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Csharp Docs is an agent skill from github/awesome-copilot, published by the product's own GitHub organization. Ensure that C types are documented with XML comments and follow best practices for documentation.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with C#. The repository describes itself as: Community-contributed instructions, agents, skills, and configurations to help you make the most of GitHub Copilot. The licence is MIT.

Example prompts

  • “/csharp-docs”

What it can do on your machine

Read from SKILL.md and the folder at commit 727ff2e. 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.

    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

Csharp Docs loads about 1k tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 564 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~28
When it runs · the whole SKILL.md, loaded when a task matches
~1k

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.

description
Ensure that C# types are documented with XML comments and follow best practices for documentation.

C# Documentation Best Practices

  • Public members should be documented with XML comments.
  • It is encouraged to document internal members as well, especially if they are complex or not self-explanatory.

Guidance for all APIs

  • Use <summary> to provide a brief, one sentence, description of what the type or member does. Start the summary with a present-tense, third-person verb.
  • Use <remarks> for additional information, which can include implementation details, usage notes, or any other relevant context.
  • Use <see langword> for language-specific keywords like null, true, false, int, bool, etc.
  • Use <c> for inline code snippets.
  • Use <example> for usage examples on how to use the member.
    • Use <code> for code blocks. <code> tags should be placed within an <example> tag. Add the language of the code example using the language attribute, for example, <code language="csharp">.
  • Use <see cref> to reference other types or members inline (in a sentence).
  • Use <seealso> for standalone (not in a sentence) references to other types or members in the "See also" section of the online docs.
  • Use <inheritdoc/> to inherit documentation from base classes or interfaces.
    • Unless there is major behavior change, in which case you should document the differences.

Methods

  • Use <param> to describe method parameters.
    • The description should be a noun phrase that doesn't specify the data type.
    • Begin with an introductory article.
    • If the parameter is a flag enum, start the description with "A bitwise combination of the enumeration values that specifies...".
    • If the parameter is a non-flag enum, start the description with "One of the enumeration values that specifies...".
    • If the parameter is a Boolean, the wording should be of the form "<see langword="true" /> to ...; otherwise, <see langword="false" />.".
    • If the parameter is an "out" parameter, the wording should be of the form "When this method returns, contains .... This parameter is treated as uninitialized.".
  • Use <paramref> to reference parameter names in documentation.
  • Use <typeparam> to describe type parameters in generic types or methods.
  • Use <typeparamref> to reference type parameters in documentation.
  • Use <returns> to describe what the method returns.
    • The description should be a noun phrase that doesn't specify the data type.
    • Begin with an introductory article.
    • If the return type is Boolean, the wording should be of the form "<see langword="true" /> if ...; otherwise, <see langword="false" />.".

Constructors

  • The summary wording should be "Initializes a new instance of the <Class> class [or struct].".

Properties

  • The <summary> should start with:
    • "Gets or sets..." for a read-write property.
    • "Gets..." for a read-only property.
    • "Gets [or sets] a value that indicates whether..." for properties that return a Boolean value.
  • Use <value> to describe the value of the property.
    • The description should be a noun phrase that doesn't specify the data type.
    • If the property has a default value, add it in a separate sentence, for example, "The default is <see langword="false" />".
    • If the value type is Boolean, the wording should be of the form "<see langword="true" /> if ...; otherwise, <see langword="false" />. The default is ...".

Exceptions

  • Use <exception cref> to document exceptions thrown by constructors, properties, indexers, methods, operators, and events.
  • Document all exceptions thrown directly by the member.
  • For exceptions thrown by nested members, document only the exceptions users are most likely to encounter.
  • The description of the exception describes the condition under which it's thrown.
    • Omit "Thrown if ..." or "If ..." at the beginning of the sentence. Just state the condition directly, for example "An error occurred when accessing a Message Queuing API."

Can I use Csharp Docs in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders.

To copy it by hand, put the folder in .cursor/skills/csharp-docs, .gemini/skills/csharp-docs, .github/skills/csharp-docs and .opencode/skills/csharp-docs in your project.

What does Csharp Docs need to run?

SKILL.md names no scripts, command-line tools or credentials: Csharp Docs is instructions for the agent only.

Does Csharp Docs access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
