coverage▌

Create institutional-quality equity research initiation reports through a structured 5-task workflow. Each task must be executed separately with verified inputs.

This skill guides you through improving type coverage in Python files using Pyrefly, Meta's type checker. Follow this systematic process to add proper type annotations to files.

Use this skill whenever coverage needs assessment or improvement (coverage regressions, failing thresholds, or user requests for stronger tests). It runs the coverage suite, analyzes results, highlights the biggest gaps, and prepares test additions while confirming with the user before changing code.

Guides press coverage and media mentions aggregation—showcasing third-party coverage from authoritative sites to build trust. Optional page; when coverage is sparse, implement as a small "As Seen In" or "As Featured In" section on homepage or elsewhere. Distinct from media-kit-page-generator (assets for journalists). For conceptual overview and comparison table, see reference.md.

Map all testable surfaces in the application and identify what's tested vs. what's missing.

Measure code exercised during fuzzing to assess harness effectiveness and identify blockers. \n \n Supports LLVM, GCC, and Rust instrumentation with step-by-step workflows for building coverage-instrumented binaries and executing them against fuzzing corpora \n Provides detailed guidance on generating text and HTML reports using llvm-cov, gcovr, and cargo-fuzz, including filtering harness code and handling large codebases \n Includes practical patterns for identifying magic value checks, handlin

Run pytest with coverage reporting to identify and eliminate untested code lines. \n \n Generates annotated source files in cov_annotate/ directory, with ! markers indicating uncovered lines \n Supports module-specific coverage checks via --cov=module_name and targeted test runs on specific test files \n Workflow: run coverage, review annotated files for uncovered lines, write tests to cover gaps, repeat until 100% coverage achieved \n
