What it does

Coverage Report is an agent skill from NikiforovAll/claude-code-rules. Generate a .NET code coverage report scoped to files changed in the current branch. Runs tests with coverage collection and produces filtered HTML reports.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Test coverage. It works with .NET. The repository describes itself as: Learn practical techniques to enhance your AI-assisted development workflow with Claude Code. The licence is Apache-2.0.

When your agent uses it

Tasks that involve Test coverage

Example prompts

“/coverage-report”

Requirements

Pre-approved tools (allowed-tools): Bash(dotnet test:*), Bash(dotnet reportgenerator:*), Bash(git diff:*), Bash(git merge-base:*), Bash(start:*), Read, Grep, Glob

Workflow steps

8 steps, taken from the step headings in SKILL.md.

Determine base branch
Detect changed source files
Identify test project(s)
Clean previous results
Run tests with coverage
Build file filters
Generate report
Display results

What it can do on your machine

Read from SKILL.md and the folder at commit 281c063. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Bash(dotnet test:*)
- Bash(dotnet reportgenerator:*)
- Bash(git diff:*)
- Bash(git merge-base:*)
- Bash(start:*)
- Read
- Grep
- Glob
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- git
- dotnet
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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.

Context cost

Coverage Report loads about 634 tokens when it runs. Until then it costs about 43 tokens; SKILL.md has 219 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~43
When it runs · the whole SKILL.md, loaded when a task matches: ~634

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.

Code Coverage Report

Generate a code coverage report scoped to source files changed in the current branch compared to a base branch.

Workflow

1. Determine base branch

Detect the base branch to diff against. Use the MR/PR target branch if known, otherwise default to main or master (whichever exists). Ask the user if ambiguous.

bash

git merge-base --fork-point main HEAD || git merge-base --fork-point master HEAD

2. Detect changed source files

bash

git diff <base-branch> --name-only -- '*.cs'

Filter out test files (paths containing Test, Tests, .Tests, .Test). If no source files changed, stop and inform the user.

3. Identify test project(s)

Determine which test project(s) to run. Strategies (in order):

User-specified: If the user names a test project, use it
Convention-based: Look for test projects whose name matches the changed project (e.g., MyProject -> MyProject.Tests)
Solution-wide: Run all tests in the solution if scope is unclear
Ask: If ambiguous, ask the user which test project(s) to run

4. Clean previous results

bash

rm -rf TestResults/

5. Run tests with coverage

bash

dotnet test <test-project-or-solution> \
  --collect:"XPlat Code Coverage" \
  --results-directory ./TestResults/

6. Build file filters

From the changed file list (step 2), extract basenames and build a filter string:

+*FileName1.cs;+*FileName2.cs;+*FileName3.cs

7. Generate report

bash

dotnet reportgenerator \
  -reports:"TestResults/**/coverage.cobertura.xml" \
  -targetdir:"TestResults/CoverageReport" \
  -reporttypes:"Html;TextSummary" \
  -filefilters:"<filters>"

8. Display results

Print TestResults/CoverageReport/Summary.txt to the terminal
Open the HTML report (platform-aware):
- Windows: start TestResults/CoverageReport/index.html
- macOS: open TestResults/CoverageReport/index.html
- Linux: xdg-open TestResults/CoverageReport/index.html

Tips

For large solutions, scope to specific test projects to speed up collection
The -filefilters flag accepts wildcards -- basename matching avoids path sensitivity
