reportgenerator

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

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. Keep collection and rendering separate: Coverlet collects, ReportGenerator renders.
2. Prefer the local or manifest-based .NET tool for reproducible CI runs.
3. Choose output formats deliberately:
   • HtmlSummary
   • Cobertura
   • MarkdownSummaryGithub
   • badges
4. Merge multiple reports only when the repo really needs a consolidated view.

Bootstrap When Missing

If ReportGenerator is not configured yet:

1. Detect current state:
   • rg --files -g '.config/dotnet-tools.json'
   • dotnet tool list --local
   • dotnet tool list --global
   • command -v reportgenerator
2. Prefer local tool installation for reproducible CI:
   • dotnet new tool-manifest (if missing)
   • dotnet tool install dotnet-reportgenerator-globaltool
3. 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"
4. Run the report command once and return status: configured or status: improved.
5. 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.

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.
