spike-guidance-adversarial skillA

spike-guidance-adversarial is agent-read markdown (skill) from testdouble/han: OI-3 spike harness — ADVERSARIAL inline guidance variant. Worst-case anchor: ends with a final-sounding completion statement and gives NO instruction to return to the caller. Use only when a spike consumer skill invokes it..

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

Latest version
mdr add testdouble/han/spike-guidance-adversarial@git:20260709.3f87cf9
Exact content
mdr add testdouble/han/spike-guidance-adversarial@sha256:d1f9acb0b20b8a84

Pin 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.
