agent-supply-chain SKILL.md skillA
agent-supply-chain from fabioc-aloha/alex_skill_mall is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fabioc-aloha/alex_skill_mall/agent-supply-chain@git:20260728.80a7ab6Pins git:20260728.80a7ab6 in mdr.lock. Pin the fingerprint instead.

Generate and verify integrity manifests for AI agent plugins and tools -- detect tampering, enforce version pinning, and establish supply chain provenance (the SLSA/Sigstore gap for agent ecosystems).
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 plugins and tools. Detect tampering, enforce version pinning, and establish supply chain provenance.
## Overview
Agent plugins and MCP servers have the same supply chain risks as npm packages or container images — except the ecosystem has no equivalent of npm provenance, Sigstore, or SLSA. This skill fills that gap.
```
Plugin Directory → Hash All Files (SHA-256) → Generate INTEGRITY.json
↓
Later: Plugin Directory → Re-Hash Files → Compare Against INTEGRITY.json
↓
Match? VERIFIED : TAMPERED
```
## When to Use
- Before promoting a plugin from development to production
- During code review of plugin PRs
- As a CI step to verify no files were modified after review
- When auditing third-party agent tools or MCP servers
- Building a plugin marketplace with integrity requirements
---
## Pattern 1: Generate Integrity Manifest
Create a deterministic `INTEGRITY.json` with SHA-256 hashes of all plugin files.
```python
import hashlib
import json
…Read the whole file at its exact version.
How to install
mdr add fabioc-aloha/alex_skill_mall/agent-supply-chain@sha256:52545d67f2639716The line at the top of this page pins the label git:20260728.80a7ab6, 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.
