agent-supply-chain SKILL.md skillA
agent-supply-chain from marielynneblock/arcanum-artifex is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add marielynneblock/arcanum-artifex/agent-supply-chain@git:20260520.f6c6e91Pins git:20260520.f6c6e91 in mdr.lock. Pin the fingerprint instead.

Review, generate, and verify supply-chain integrity controls for AI agent tools, plugins, MCP servers, skills, prompts, and custom agents, including SHA-256 manifests, dependency pinning, provenance evidence, promotion gates, and CI verification.
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 Supply Chain Integrity
Generate and verify integrity manifests for AI agent tools, plugins, MCP servers, skills, prompts, and custom agents. Detect unexpected file changes, enforce dependency pinning, and capture provenance evidence before promotion.
## Overview
Agent assets often combine executable code, prompts, policy files, and tool configuration. Treat them as deployable software: pin dependencies, record what was reviewed, verify the reviewed files before release, and fail closed when integrity evidence is missing.
```
Agent Asset Folder -> Hash Reviewable Files -> Generate INTEGRITY.json
Later CI -> Re-hash Files -> Compare Hashes + Manifest Hash
Result -> verified | modified | missing | untracked | invalid
```
This skill provides lightweight integrity controls. It does not replace signed releases, SLSA provenance, SBOM tooling, vulnerability scanning, or organisation-specific release policy.
## Use This Skill When
- Promoting an agent tool, plugin, MCP server, skill, prompt, or custom agent to a shared or production environment
- Reviewing a pull request that adds or changes agent-executable code, tool configuration, or bundled instructions

How to install
mdr add marielynneblock/arcanum-artifex/agent-supply-chain@sha256:f26023f86501cb7eThe line at the top of this page pins the label git:20260520.f6c6e91, 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.
