dotnet-reportgenerator

Original：🇺🇸 English

Translated

Use the open-source free `ReportGenerator` tool for turning .NET coverage outputs into HTML, Markdown, Cobertura, badges, and merged reports. Use when raw coverage files are not readable enough for CI or human review.

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.md
```
and confirm scope and constraints.
Run this skill's
```
Workflow
```
through the
```
Ralph Loop
```
until outcomes are acceptable.
Return the
```
Required Result Format
```
with 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.md

and 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: configured
```
or
```
status: 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_applicable
```
with explicit reason and fallback path.

For setup-only requests with no execution, return

and exact next commands.
