Metrics Report (codebase test & coverage analyzer)

What it does

This skill automates end-to-end repository test analysis: it discovers test files across stacks, runs available test suites, parses coverage reports, maps tests to source files (tool + LLM mapping), evaluates test quality, and emits a structured metrics JSON and a small web UI for browsing trends. It's built to produce actionable test health dashboards.

When to use it

Invoke when you need an automated health audit of a codebase — continuous integration checks, pre-release quality gates, or as a developer tool for understanding test coverage and gaps across frontend and backend. Good for polyglot repos (Node, Python, Java, Rust).

What's included

• Scripts: includes a metrics-report/ app and helper scripts in the repo (has_scripts detected=false in fetch output, but repository contains a metrics-report directory)
• References: repo contains design notes and sample apps to exercise the reporter (has_references=false)
• Instructions: detailed phased workflow for detection, scanning, running tests, parsing coverage, LLM-assisted mapping, scoring, and publishing a metrics JSON and history snapshots.

Compatible agents

Designed for developer/ops agents that can run shell commands and parse outputs (agents with Bash/Glob/Grep capabilities). Works with Claude Code, Cursor, and CLI-capable assistants.
