dependency-verification SKILL.md skillA
dependency-verification 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/dependency-verification@git:20260713.f98719bPins git:20260713.f98719b in mdr.lock. Pin the fingerprint instead.

Verifies a package exists before install, defending against hallucination and slopsquatting. Use when adding, recommending, or installing a package.
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
> A package name the model produced is a claim, not a fact. The > registry is the fact. Verify before you install. # Dependency Verification ## Overview Code-generating language models recommend packages that do not exist at a measured rate of 5.2% (commercial models) to 21.7% (open models) across 576,000 samples (Spracklen et al. 2024, arXiv 2406.10279). Worse, 58% of hallucinated names recur across reruns, so an attacker can predict them, register the empty name, and ship malware. This is "slopsquatting." A proof-of-concept package (`huggingface-cli`) drew over 30,000 downloads after being registered against a commonly hallucinated name. Package hallucination is also inversely correlated with coding-benchmark score, so a better model does not make this go away. The defense is cheap: confirm the name exists in its registry before installing or recommending it. This skill defines that check and is enforced by the `guard_package_hallucination.py` PreToolUse hook. ## When To Use Apply before any of these: - Running `pip install`, `uv add`, `npm install`, `pnpm add`, `yarn add`, `cargo add`, `poetry add`, or `pdm add`. …

How to install
mdr add athola/claude-night-market/dependency-verification@sha256:0756f5bb8aa97202The line at the top of this page pins the label git:20260713.f98719b, 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.
