/configure:coverage

Check and configure code coverage thresholds and reporting for test frameworks.

When to Use This Skill

Use this skill when...

Use another approach when...

Setting up coverage thresholds for Vitest, Jest, pytest, or Rust

Running tests with coverage (

/test:coverage

)

Configuring coverage reporters (text, JSON, HTML, lcov)

Configuring the test framework itself (

/configure:tests

)

Adding Codecov or Coveralls integration to CI/CD

Analyzing test failures (test-runner agent)

Auditing coverage configuration compliance across a project

Writing individual test cases

Adjusting coverage threshold percentages

Configuring general CI/CD workflows (

/configure:workflows

)

Context

Project root: !

pwd

Package files: !

find . -maxdepth 1 ( -name 'package.json' -o -name 'pyproject.toml' -o -name 'Cargo.toml' )

Vitest config: !

find . -maxdepth 1 -name 'vitest.config.*'

Jest config: !

find . -maxdepth 1 -name 'jest.config.*'

Coverage dir: !

find . -maxdepth 1 -type d -name 'coverage'

Codecov config: !

find . -maxdepth 1 ( -name 'codecov.yml' -o -name '.codecov.yml' )

Project standards: !

find . -maxdepth 1 -name '.project-standards.yaml'

Parameters

Parse from command arguments:

--check-only

Report compliance status without modifications (CI/CD mode)

--fix

Apply fixes automatically without prompting

--threshold

Set coverage threshold (default: 80)

Default threshold

80% (lines, branches, functions, statements)

Supported frameworks:

Vitest

:

@vitest/coverage-v8

or

@vitest/coverage-istanbul

Jest

Built-in coverage with --coverage pytest : pytest-cov plugin Rust : cargo-llvm-cov or cargo-tarpaulin Execution Execute this code coverage compliance check: Step 1: Detect test framework and coverage configuration Check for framework indicators: Indicator Framework Coverage Tool vitest.config. with coverage Vitest @vitest/coverage-v8 jest.config. with coverage Jest Built-in pyproject.toml [tool.coverage] pytest pytest-cov .cargo/config.toml with coverage Rust cargo-llvm-cov Use WebSearch or WebFetch to verify latest versions of coverage tools before configuring. Step 2: Analyze current coverage state For the detected framework, check configuration completeness: Vitest: Coverage provider configured ( v8 or istanbul ) Coverage reporters configured ( text , json , html , lcov ) Thresholds set for lines, functions, branches, statements Exclusions configured (node_modules, dist, tests, config files) Output directory specified Jest: collectCoverage enabled coverageProvider set ( v8 or babel ) collectCoverageFrom patterns configured coverageThresholds configured coverageReporters configured pytest: pytest-cov installed [tool.coverage.run] section exists [tool.coverage.report] section exists Coverage threshold configured ( --cov-fail-under ) Rust (cargo-llvm-cov): cargo-llvm-cov installed Coverage configuration in workspace HTML/LCOV output configured Step 3: Generate compliance report Print a formatted compliance report: Code Coverage Compliance Report ================================ Project: [name] Framework: [Vitest 2.x | pytest 8.x | cargo-llvm-cov 0.6.x] Coverage Configuration: Provider @vitest/coverage-v8 [CONFIGURED | MISSING] Reporters text, json, html, lcov [ALL | PARTIAL] Output directory coverage/ [CONFIGURED | DEFAULT] Exclusions node_modules, dist, tests [CONFIGURED | INCOMPLETE] Thresholds: Lines 80% [PASS | LOW | NOT SET] Branches 80% [PASS | LOW | NOT SET] Functions 80% [PASS | LOW | NOT SET] Statements 80% [PASS | LOW | NOT SET] CI/CD Integration: Coverage upload codecov/coveralls [CONFIGURED | MISSING] Artifact upload coverage reports [CONFIGURED | MISSING] Overall: [X issues found] If --check-only , stop here. Step 4: Configure coverage (if --fix or user confirms) Apply coverage configuration based on detected framework. Use templates from REFERENCE.md : Install coverage provider (e.g., @vitest/coverage-v8 , pytest-cov ) Update config file with thresholds, reporters, exclusions Add scripts to package.json or pyproject.toml Configure CI/CD with Codecov upload and artifact storage Step 5: Update standards tracking Update .project-standards.yaml : standards_version : "2025.1" last_configured : "[timestamp]" components : coverage : "2025.1" coverage_threshold : 80 coverage_provider : "[v8|istanbul|pytest-cov|llvm-cov]" coverage_reporters : [ "text" , "json" , "html" , "lcov" ] coverage_ci : "codecov" Step 6: Print final report Print a summary of changes applied, scripts added, and next steps for verifying coverage. For detailed configuration templates, see REFERENCE.md . Agentic Optimizations Context Command Quick compliance check /configure:coverage --check-only Auto-fix all issues /configure:coverage --fix Custom threshold /configure:coverage --fix --threshold 90 Check coverage config exists find . -maxdepth 1 -name 'vitest.config.' -o -name 'jest.config.' 2>/dev/null Verify coverage directory test -d coverage && echo "EXISTS" Flags Flag Description --check-only Report status without offering fixes --fix Apply all fixes automatically without prompting --threshold Set coverage threshold (default: 80) Examples

Check compliance and offer fixes

/configure:coverage

Check only, no modifications

/configure:coverage --check-only

Auto-fix with custom threshold

/configure:coverage

--fix

--threshold

90

Error Handling
