technical-spike skillA

technical-spike is agent-read markdown (skill) from yarlson/yarstack: Resolve one correctness-blocking external or version-specific technical uncertainty through bounded investigation. Use when cheap local inspection cannot establish framework, library, tool, runtime, protocol, or platform behavior needed by the current task..

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 yarlson/yarstack/technical-spike@git:20260718.f44cf0d
Exact content
mdr add yarlson/yarstack/technical-spike@sha256:61bc16fbdc8bbc52

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.
