# Coverage > Collect and enforce code coverage using Deno Use when this capability is needed. - Skill: `tomevault-io/coverage-6` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/coverage-6` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/coverage-6/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/coverage-6 --- ## What I do - Run `deno task coverage` to collect coverage data for the codebase - Can also collect coverage for a specific file using `deno task coverage ` - Use `deno task coverage:check` to enforce coverage thresholds defined in `.denocoveragerc` - Use `deno task serve:coverage` to serve an HTML coverage report in the browser ## When to use me Use this when you want to measure or verify test coverage: - After adding new tests - Before submitting a pull request (coverage must meet 100% thresholds) - When debugging which areas of the code are under-tested - To inspect coverage gaps interactively ## Notes - Coverage thresholds are defined in `.denocoveragerc` (100% for lines, branches, and functions) - Every test change must be accompanied by coverage that satisfies these thresholds - The HTML report is helpful for visualizing failing areas in complex serialization paths --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/sachitv) — claim your Tome and manage your conversions.
