check-coverage SKILL.md skillA
check-coverage from sd0xdev/sd0x-harness is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add sd0xdev/sd0x-harness/check-coverage@git:20260404.1c6641cPins git:20260404.1c6641c in mdr.lock. Pin the fingerprint instead.

Comprehensive assessment of Unit / Integration / E2E three-layer test coverage, identify gaps and provide actionable recommendations.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says

## Agent Dispatch
```
Agent({
description: "Assess three-layer test coverage and identify gaps",
subagent_type: "coverage-analyst",
prompt: `Assess Unit / Integration / E2E test coverage for the feature docs at: $ARGUMENTS
Follow the steps defined in this skill.`
})
```
## Task
### Step 1: Read Feature Documentation
Read specified feature docs. Extract:
- Feature name and objectives
- Involved Service / Provider / Entity
- Core flows and boundary conditions
### Step 2: Identify Related Source Code
Search related source code based on feature documentation. Build source code inventory.
### Step 3: Map Test Files
Check whether each source file has corresponding tests (unit, integration, e2e).
### Step 4: Analyze Coverage Gaps
For each source file:
…Read the whole file at its exact version.
How to install
mdr add sd0xdev/sd0x-harness/check-coverage@sha256:697803fa61969ee7The line at the top of this page pins the label git:20260404.1c6641c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
