Check that a Copilot customisation asset (skill, workflow, agent, instruction, or prompt folder) stays standalone and copyable, with no runtime dependency on paths outside its own folder. Use when packaging an asset for reuse, reviewing whether an asset can be copied out of this repo, or investigating why a copied asset breaks elsewhere.

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

# Asset Self-Containment Check

Check one asset folder for hidden dependencies on the rest of this repository, then report or fix deviations. This is distinct from [markdown-link-auditor](../markdown-link-auditor/SKILL.md), which checks whether links *resolve*; this skill checks whether an asset's references *escape its own package* — the "packaging over linking" rule stated in this repo's `.github/copilot-instructions.md`.

## Use this skill when

- An asset is being prepared for copying into another repository or a personal customisation folder.
- A review needs evidence that an asset does not silently depend on sibling repo paths.
- An asset behaves correctly here but is suspected to break once extracted.

## What counts as an asset

A single self-contained unit: a `SKILL.md` folder, a `WORKFLOW.md` folder, one `*.agent.md` file (plus any folder it bundles resources in), one `*.instructions.md` file, or one `*.prompt.md` file.

## Audit workflow

1. **Define scope.** Identify the one asset folder or file to check. If the user names a parent folder containing multiple assets, ask which asset to check unless exactly one exists there.

How to install

The exact contents, by fingerprint
mdr add marielynneblock/arcanum-artifex/asset-self-containment-check@sha256:9c6f69b8fff561dc

The line at the top of this page pins the label v1.0.0, 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.
