One thing to look at

  • 7 stars7 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Use the open-source free `coverlet` toolchain for .NET code coverage. Use when a repo needs line and branch coverage, collector versus MSBuild driver selection, or CI-safe coverage commands.

Coverlet for .NET

Trigger On

  • the repo uses or wants coverlet
  • CI needs line or branch coverage for .NET tests
  • the team needs to choose between coverlet.collector, coverlet.msbuild, or coverlet.console

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

  • coverage report rendering by itself
  • repos that intentionally use a different coverage engine

Inputs

  • the nearest AGENTS.md
  • active runner model: VSTest or Microsoft.Testing.Platform
  • target test projects

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. Choose the driver deliberately:
    • coverlet.collector for VSTest dotnet test --collect
    • coverlet.msbuild for MSBuild property-driven runs
    • coverlet.console for standalone scenarios
  2. Add coverage packages only to test projects.
  3. Do not mix coverlet.collector and coverlet.msbuild in the same test project.
  4. Pair raw coverage collection with ReportGenerator only when humans need rendered reports.

Bootstrap When Missing

If coverage is not configured yet:

  1. Detect current state:
    • rg -n "coverlet\\.(collector|msbuild)|CollectCoverage|XPlat Code Coverage" -g '*.csproj' -g '*.props' -g '*.targets' .
    • dotnet tool list --local
    • dotnet tool list --global
    • command -v coverlet
  2. Install exactly one driver path:
    • VSTest collector: dotnet add TEST_PROJECT.csproj package coverlet.collector
    • MSBuild driver: dotnet add TEST_PROJECT.csproj package coverlet.msbuild
    • Console tool: dotnet new tool-manifest (if missing) and dotnet tool install coverlet.console
  3. Record one concrete local and CI command in AGENTS.md:
    • collector: dotnet test TEST_PROJECT.csproj --collect:"XPlat Code Coverage"
    • msbuild: dotnet test TEST_PROJECT.csproj /p:CollectCoverage=true /p:CoverletOutputFormat=cobertura
    • console: dotnet tool run coverlet TEST_ASSEMBLY.dll --target "dotnet" --targetargs "test TEST_PROJECT.csproj --no-build"
  4. Run the chosen command once and return status: configured or status: improved.
  5. If another coverage engine already owns coverage for this repo, return status: not_applicable.

Deliver

  • explicit coverage driver selection
  • reproducible coverage commands for local and CI runs

Validate

  • coverage driver matches the runner model
  • coverage files are stable and consumable by downstream reporting

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.
