ReportGenerator for.NET
Trigger On
- the repo uses or wants
ReportGenerator - CI needs human-readable coverage reports
- multiple coverage files must be merged
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
- raw coverage collection with no reporting need
Inputs
- the nearest
AGENTS.md - existing coverage artifacts
- desired output formats
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
- Keep collection and rendering separate: Coverlet collects, ReportGenerator renders.
- Prefer the local or manifest-based.NET tool for reproducible CI runs.
- Choose output formats deliberately:
- HtmlSummary - Cobertura - MarkdownSummaryGithub - badges
- Merge multiple reports only when the repo really needs a consolidated view.
Bootstrap When Missing
If ReportGenerator is not configured yet:
- Detect current state:
- rg --files -g '.config/dotnet-tools.json' - dotnet tool list --local - dotnet tool list --global - command -v reportgenerator
- Prefer local tool installation for reproducible CI:
- dotnet new tool-manifest (if missing) - dotnet tool install dotnet-reportgenerator-globaltool
- Add one explicit render command to
AGENTS.mdand CI, for example:
- dotnet tool run reportgenerator -reports:"**/coverage.cobertura.xml" -targetdir:"artifacts/coverage" -reporttypes:"HtmlSummary;Cobertura"
- Run the report command once and return
status: configuredorstatus: improved. - If raw coverage outputs are already sufficient and no rendered artifacts are needed, return
status: not_applicable.
Deliver
- readable coverage artifacts for humans and CI systems
- explicit report-generation commands
Validate
- report inputs match the generated coverage format
- generated reports land in a stable artifact path
Ralph Loop
Use the Ralph Loop for every task, including docs, architecture, testing, and tooling work.
- 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
- Execute one planned step and produce a concrete delta.
- Review the result and capture findings with actionable next fixes.
- Apply fixes in small batches and rerun the relevant checks or review steps.
- Update the plan after each iteration.
- Repeat until outcomes are acceptable or only explicit exceptions remain.
- If a dependency is missing, bootstrap it or return
status: not_applicablewith explicit reason and fallback path.

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