failure-mode-enumeration skillA
failure-mode-enumeration is agent-read markdown (skill) from rlaope/ultraprompt: Systematically enumerate how code can break — boundaries, concurrency, partial failure, malicious input, time, resource exhaustion — before writing defenses, then convert the list into tests and guards while pruning paranoia that does not pay rent..
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 rlaope/ultraprompt/failure-mode-enumeration@git:20260915.a5ced99mdr add rlaope/ultraprompt/failure-mode-enumeration@sha256:fc293c1e8be515bbPin 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.
