scenario skillA
scenario is agent-read markdown (skill) from vanducng/skills: Generate comprehensive edge cases and test scenarios by decomposing a feature or file across 12 risk dimensions, or blast-radius review a change with --diff: what breaks beyond the diff, proven by running real code. Use for pre-implementation risk discovery, QA planning, regression design, exhaustive edge-case enumeration, and change-safety review. Triggers: 'edge cases for X', 'what could break', 'blast radius', 'what could this break beyond the diff', 'test scenarios', 'QA plan', 'risk discove.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
How to install
mdr add vanducng/skills/scenario@v0.2.0mdr add vanducng/skills/scenario@sha256:5af045bc821a44c5Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
