fsl skillA

fsl is agent-read markdown (skill) from ymm-oss/fsl: Shared FSL language and verifier reference for writing, checking, verifying, repairing, explaining, mutating, refining, replaying, generating scenarios/test scaffolds, and interpreting fslc JSON results. Use directly for FSL syntax, kernel specs, verifier errors, repair loops, and command usage. For role-specific authoring, prefer fsl-business for business flows, fsl-requirements for PM requirements/acceptance/NFR specs, and fsl-design for engineering design/refinement work..

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/fsl@git:20260915.d7893bb
Exact content
mdr add ymm-oss/fsl/fsl@sha256:995dd2995ff51960

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.
