What it does

Mcaf Dotnet Xunit is an agent skill from managedcode/Storage. Write, run, or repair .NET tests that use xUnit. Use when a repo uses xunit, xunit.v3, [Fact], [Theory], or xunit.runner.visualstudio, and you need the right CLI, package, and runner guidance for xUnit on VSTest or Microsoft.Testing.Platform.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/xunit.md`). Compatibility notes: Requires a .NET solution or project with xUnit packages; respects the repo's AGENTS.md commands first.

It sits in Testing & QA, covering Unit testing. It works with .NET. The repository describes itself as: Storage library provides a universal interface for accessing and manipulating data in different cloud blob storage providers. The licence is MIT.

When your agent uses it

  • A repo uses xunit
  • Xunit.runner.visualstudio
  • You need the right CLI
  • Runner guidance for xUnit on VSTest

Example prompts

  • “/mcaf-dotnet-xunit”

Requirements

  • Compatibility (from SKILL.md): Requires a .NET solution or project with xUnit packages; respects the repo's `AGENTS.md` commands first.

Workflow steps

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

  1. Read the nearest AGENTS.md and confirm scope and constraints.
  2. Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
  3. Return the Required Result Format with concrete artifacts and verification evidence.

What it can do on your machine

Read from SKILL.md and the folder at commit 5d32121. 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
    • rg

    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.

  • Compatibility

    Requires a .NET solution or project with xUnit packages; respects the repo's `AGENTS.md` commands first.

    From compatibility in the SKILL.md frontmatter.

Context cost

Mcaf Dotnet Xunit loads about 1.3k tokens when it runs, and up to ~2.1k if it reads all its reference files. Until then it costs about 68 tokens; SKILL.md has 629 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~68
When it runs · the whole SKILL.md, loaded when a task matches
~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.1k

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
Write, run, or repair .NET tests that use xUnit. Use when a repo uses `xunit`, `xunit.v3`, `[Fact]`, `[Theory]`, or `xunit.runner.visualstudio`, and you need the right CLI, package, and runner guidance for xUnit on VSTest or Microsoft.Testing.Platform.

MCAF: .NET xUnit

Trigger On

  • the repo uses xUnit v2 or xUnit v3
  • you need to add, run, debug, or repair xUnit tests
  • the team is unsure whether a project is using VSTest or Microsoft.Testing.Platform

Value

  • produce a concrete project delta: code, docs, config, tests, CI, or review artifact
  • reduce ambiguity through explicit planning, verification, and final validation skills
  • leave reusable project context so future tasks are faster and safer

Do Not Use For

  • TUnit projects
  • MSTest projects
  • generic test strategy with no xUnit-specific mechanics

Inputs

  • the nearest AGENTS.md
  • the test project file and package references
  • the active runner model for the test project

Quick Start

  1. Read the nearest AGENTS.md and confirm scope and constraints.
  2. Run this skill's Workflow through the Ralph Loop until outcomes are acceptable.
  3. Return the Required Result Format with concrete artifacts and verification evidence.

Workflow

  1. Detect the active xUnit model before changing commands:
    • xunit usually means v2
    • xunit.v3 means v3
    • xunit.runner.visualstudio plus Microsoft.NET.Test.Sdk usually means VSTest compatibility is enabled
    • TestingPlatformDotnetTestSupport or UseMicrosoftTestingPlatformRunner means Microsoft.Testing.Platform is in play
  2. Read the repo's real test command from AGENTS.md. If the repo has no explicit command yet, start with dotnet test PROJECT_OR_SOLUTION.
  3. Keep the runner model consistent:
    • xUnit v2 usually runs through VSTest
    • xUnit v3 can run as a standalone executable with dotnet run
    • xUnit v3 can also integrate with Microsoft.Testing.Platform
    • do not mix VSTest-only switches into Microsoft.Testing.Platform runs
  4. Run the narrowest useful scope first:
    • one project
    • one class
    • one trait
    • one method
  5. Prefer [Theory] for stable data-driven coverage and [Fact] for single-path invariant checks.
  6. Keep xunit.analyzers enabled when present. Fix analyzer findings instead of muting them casually.

Bootstrap When Missing

If xUnit is requested but not configured:

  1. Detect current framework first:
    • rg -n "xunit(\\.v3)?|xunit\\.runner\\.visualstudio|TestingPlatformDotnetTestSupport|UseMicrosoftTestingPlatformRunner|TUnit|MSTest" -g '*.csproj' .
  2. If the repo currently uses TUnit or MSTest, do not auto-migrate. Return status: not_applicable unless migration is explicitly requested.
  3. For explicit xUnit adoption, add packages to the target test project:
    • dotnet add TEST_PROJECT.csproj package xunit.v3
    • optional VSTest bridge: dotnet add TEST_PROJECT.csproj package xunit.runner.visualstudio
  4. Add repo test commands and runner notes to AGENTS.md.
  5. Run dotnet test TEST_PROJECT.csproj or repo-defined xUnit command and return status: configured or status: improved.

Deliver

  • xUnit tests that match the repo's active xUnit version and runner
  • commands that work in local and CI runs
  • focused verification before broader suite execution

Validate

  • the chosen CLI matches the active runner model
  • test filters or focused runs are valid for that runner
  • tests use deterministic inputs and assertions
  • xUnit-specific analyzers remain active unless the repo documents an exception

Ralph Loop

Use the Ralph Loop for every task, including docs, architecture, testing, and tooling work.

  1. Plan first (mandatory):
    • analyze current state
    • define target outcome, constraints, and risks
    • write a detailed execution plan
    • list final validation skills to run at the end, with order and reason
  2. Execute one planned step and produce a concrete delta.
  3. Review the result and capture findings with actionable next fixes.
  4. Apply fixes in small batches and rerun the relevant checks or review steps.
  5. Update the plan after each iteration.
  6. Repeat until outcomes are acceptable or only explicit exceptions remain.
  7. If a dependency is missing, bootstrap it or return status: not_applicable with explicit reason and fallback path.
Required Result Format
  • status: complete | clean | improved | configured | not_applicable | blocked
  • plan: concise plan and current iteration step
  • actions_taken: concrete changes made
  • validation_skills: final skills run, or skipped with reasons
  • verification: commands, checks, or review evidence summary
  • remaining: top unresolved items or none

For setup-only requests with no execution, return status: configured and exact next commands.

Load References

  • read references/xunit.md first

Example Requests

  • "Run this xUnit suite correctly."
  • "Fix our xUnit v3 test command."
  • "Add an xUnit regression test and keep CI compatible."
