supply-chain-advisory SKILL.md skillA
supply-chain-advisory from athola/claude-night-market is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add athola/claude-night-market/supply-chain-advisory@git:20261028.7246d08Pins git:20261028.7246d08 in mdr.lock. Pin the fingerprint instead.

Audits dependency supply chains for bad versions, lockfile drift, and artifact integrity. Use when adding deps, handling incidents, or releasing a plugin.
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
## Overview
Supply chain attacks bypass traditional code review by compromising upstream
dependencies. This skill provides patterns for detecting, preventing, and
responding to compromised packages in Python ecosystems.
## When To Use
- After a supply chain advisory is published
- When auditing dependencies for a new or existing project
- During incident response for a suspected compromise
- When adding the SessionStart hook to a project
## When NOT To Use
- General CVE triage unrelated to dependency supply chain
- Application-level vulnerability scanning (use a SAST tool)
- License compliance audits (different concern)
## Known-Bad Versions Blocklist
The blocklist is at `${CLAUDE_SKILL_DIR}/known-bad-versions.json`.
It is consumed by:
1. **SessionStart hook**: warns per-session when compromised
versions detected
2. **`make supply-chain-scan`**: CI/local scanning target
3. **This skill**: manual audit guidance
### Blocklist Format
```json
{
"package_name": [{
"versions": ["x.y.z"],
"date": "YYYY-MM-DD",
"description": "What the attack did",
"indicators": ["files or patterns to search for"],
"source": "advisory URL",

How to install
mdr add athola/claude-night-market/supply-chain-advisory@sha256:1e31bd4079912969The line at the top of this page pins the label git:20261028.7246d08, 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.
