guardrail-failures SKILL.md skillA
guardrail-failures from nebius/nebius-physical-ai is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add nebius/nebius-physical-ai/guardrail-failures@git:20261105.63f0ad7Pins git:20261105.63f0ad7 in mdr.lock. Pin the fingerprint instead.

Use when a guardrail test or CI gate in npa fails and you need to map the failure to its cause and fix rather than reverse-engineering the assertion.
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
# Decoding A Guardrail Failure The guardrail suite checks thousands of repository contracts. It reads the repo and checks that surfaces which must agree still agree. A failure almost always means one of two things — you changed one side of a contract and not the other, or you added something the contract requires you to register. Run the whole suite; it is cheap enough that narrowing is rarely worth it: ```bash npa/.venv/bin/python -m pytest npa/tests/guardrails -q ``` Narrow once you know the file: ```bash npa/.venv/bin/python -m pytest npa/tests/guardrails/test_tool_catalog_argv.py -q ``` Most of these tests carry a module docstring explaining the incident that caused them to exist. When the fix is not obvious, read it — it usually names the production failure the check prevents. ## Triage Order 1. Read the assertion message. These tests are written to name the fix, not just report a mismatch. 2. Identify which side of the contract you changed. The guard is almost never wrong; it is reporting that a second file needs the same edit. 3. Only weaken a pinned exemption list if the exemption is genuinely obsolete. …

How to install
mdr add nebius/nebius-physical-ai/guardrail-failures@sha256:b049053bca7793bdThe line at the top of this page pins the label git:20261105.63f0ad7, 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.
