fsl-requirements skillA

fsl-requirements is agent-read markdown (skill) from ymm-oss/fsl: Write and verify FSL requirements-layer specs for PMs/PdMs from natural-language product requirements, acceptance criteria, forbidden flows, requirement IDs, traceability, and NFRs such as permissions, audit, capacity, reliability, and SLA/deadline behavior. Use when the deliverable is a requirements specification, not business process discovery, software architecture, internal design, or implementation conformance..

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-requirements@git:20260911.246f098
Exact content
mdr add ymm-oss/fsl/fsl-requirements@sha256:da20465dca217bf9

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.
