Use this skill when you need to discover invalid, denied, failed, degraded, or unsafe-recovery scenarios from product evidence; triggers include negative scenario discovery.
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
# Negative Scenario Discovery Discover failure, denial, degradation, and unsafe-recovery paths from goals, input constraints, permissions, dependency contracts, timeout/retry, idempotency/transaction, and recovery design. Produce `NS-##`. Do not write full test cases, run fault injection, invent error codes, or declare behavior correct. ## When to Use - Use it to examine invalid input, unauthorized access, dependency failure, timeout, retry exhaustion, duplicate request, partial failure, and inconsistency. - Use it to find failure stimuli and observable outcomes outside the happy path from designs or past failures. - Use it when failure contracts are incomplete and evidence gaps, recovery choices, and Human decisions must be explicit. Do not use it only to find boundary values, write full cases, run fault injection, conduct a real incident review, or choose final copy/SLA for a team. ## Output Format Options - Use Markdown by default; when a table, CSV, or JSON is requested, preserve the same evidence, status, impact, owner, and validation fields. - Do not present a structured format or static inventory as execution, pass, approval, or release evidence. ## How to Use …

How to install
mdr add naodeng/awesome-qa-skills/negative-scenario-discovery@sha256:53dab32f3e1f60a1The line at the top of this page pins the label git:20260914.45aa88f, 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.
