Portable skill to set up end-to-end code-coverage tracking and to raise coverage. Core is scripts/coverage_report.py (stdlib-only) with four subcommands: parse (JaCoCo/Cobertura/LCOV -> normalized NDJSON), report (NDJSON -> Markdown), gaps (ranked worklist of least-covered classes/files from a coverage report, for closing coverage gaps), and wow (Kusto -> week-over-week HTML trend). Includes references for coverage generation, Kusto setup, pipeline integration, report/email integration, and the find-gaps -> write-tests -> gate loop for increasing coverage.

What
Adds the
code-coverage-onboardingskill under.github/skills/.Why
A portable, reusable skill to set up end-to-end code-coverage tracking and to address coverage gaps from a pipeline run''s coverage reports.
Contents
scripts/coverage_report.py— stdlib-only engine with four subcommands:parse— JaCoCo / Cobertura / LCOV report(s) → normalized NDJSONreport— NDJSON → Markdown summarygaps— coverage report → ranked worklist of the least-covered classes/files (drives closing coverage gaps)wow— Kusto → week-over-week HTML trend (grouped tables + Overall rows)references/— coverage generation (Gradle/AGP/Maven/.NET/Python/Node/C++/Go), Kusto setup, pipeline integration (ADO + GitHub Actions), report/email integration, and the find-gaps → write-tests → gate loop.Addressing gaps from a pipeline run
Point the
gapssubcommand at the JaCoCo XML artifacts from a pipeline run to get a prioritized list of the least-covered classes to target with new tests — e.g.:Compiled artifacts (
__pycache__,.pyc) and the packaged.skillfile are intentionally excluded.
