new-spec skillA

new-spec is agent-read markdown (skill) from ymm-oss/fsl: Author a new or substantially changed .fsl spec and take it through native check, bounded verification, induction where relevant, mutation, and vacuity evidence before completion..

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 ymm-oss/fsl/new-spec@git:20260828.927728f
Exact content
mdr add ymm-oss/fsl/new-spec@sha256:50e9c1c0e0e6f5a0

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.
