What it does

Reportgenerator is an agent skill from managedcode/dotnet-skills. Use the open-source free ReportGenerator tool for turning .NET coverage outputs into HTML, Markdown, Cobertura, badges, and merged reports. USE FOR: the repo uses or wants ReportGenerator; CI needs human-readable coverage reports; multiple coverage files must be merged. DO NOT USE FOR: raw coverage collection with no reporting need. INVOKES: inspect the repository context, edit targeted files, and run relevant build, test, lint, or validation commands when changes are made.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `manifest.json`, `references/commands.md` and `references/formats.md`). Compatibility notes: Requires coverage artifacts such as Cobertura, OpenCover, or lcov; respects the repo's AGENTS.md commands first.

It sits in Agent Workflows, covering Test coverage and Codebase knowledge for agents. It works with .NET. The repository describes itself as: Installable .NET skill catalog and CLI for Codex, Claude Code, GitHub Copilot, and Gemini. The licence is MIT.

When your agent uses it

  • : the repo uses
  • Wants ReportGenerator
  • CI needs human-readable coverage reports
  • Multiple coverage files must be merged

Example prompts

  • “/reportgenerator”

Requirements

  • Compatibility (from SKILL.md): Requires coverage artifacts such as Cobertura, OpenCover, or lcov; respects the repo's `AGENTS.md` commands first.

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  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.

What it can do on your machine

Read from SKILL.md and the folder at commit 535dd55. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • dotnet
    • rg

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Requires coverage artifacts such as Cobertura, OpenCover, or lcov; respects the repo's `AGENTS.md` commands first.

    From compatibility in the SKILL.md frontmatter.

Context cost

Reportgenerator loads about 1.1k tokens when it runs, and up to ~3.5k if it reads all its reference files. Until then it costs about 124 tokens; SKILL.md has 472 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~124
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~3.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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.
