Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.01095 |
| Opus 5 | $0.00023 | $0.00548 |
| Sonnet 5 | $0.00009 | $0.00219 |
| Haiku 4.5 | $0.00005 | $0.00110 |
Grade A, and why
dotnet-coverlet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
86% identical to mcaf-dotnet-coverlet — 10 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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, orcoverlet.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
- Read the nearest
AGENTS.mdand confirm scope and constraints. - Run this skill's
Workflowthrough theRalph Loopuntil outcomes are acceptable. - Return the
Required Result Formatwith concrete artifacts and verification evidence.
Workflow
- Choose the driver deliberately:
coverlet.collectorfor VSTestdotnet test --collectcoverlet.msbuildfor MSBuild property-driven runscoverlet.consolefor standalone scenarios
- Add coverage packages only to test projects.
- Do not mix
coverlet.collectorandcoverlet.msbuildin the same test project. - Pair raw coverage collection with
ReportGeneratoronly when humans need rendered reports.
Bootstrap When Missing
If coverage is not configured yet:
- Detect current state:
rg -n "coverlet\\.(collector|msbuild)|CollectCoverage|XPlat Code Coverage" -g '*.csproj' -g '*.props' -g '*.targets' .dotnet tool list --localdotnet tool list --globalcommand -v coverlet
- 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) anddotnet tool install coverlet.console
- VSTest collector:
- 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"
- collector:
- Run the chosen command once and return
status: configuredorstatus: improved. - If another coverage engine already owns coverage for this repo, return
status: not_applicable.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dotnet-coverlet is a skill published in the GitHub repository Postpartum-genushyacinthus29/dotnet-skills (10 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 1,095 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 86% identical to mcaf-dotnet-coverlet, differing in 10 lines, and is treated as a copy.
