Orchestrate an FSL-centered delivery workflow from business planning through PM requirements, engineering design, verification, refinement, scenarios, testgen/replay, and implementation conformance. Use when the user asks to drive a feature/project "from planning to implementation" with FSL as the backbone, connect business to requirements to design to implementation, create an end-to-end FSL development plan, or coordinate the existing fsl-business, fsl-requirements, fsl-design, and…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FSL Delivery ## Overview Use this skill as the lifecycle coordinator for FSL-based delivery. It does not replace the layer-specific skills; it routes work to them, preserves the layer boundaries, and keeps proof, refinement, and implementation-conformance claims separate. FSL is the checkable contract spine, not the entire product process — but that spine is broad by default: a spec replaces the prose business/requirements/design doc you would write anyway, so wide coverage across those layers needs no per-feature verification-ROI case. Natural language discovery, UI/API design, coding, and testing still happen in their normal tools; FSL supplies the machine-checkable contracts and counterexamples that constrain those artifacts. The resulting spec corpus is the project's living single source of truth: each layer is re-verified on every change (regression, drift, and cross-layer change-impact via `refine`), and it doubles as onboarding context for humans and AI approaching the flow it documents. ## Routing Before authoring a layer, read and follow the corresponding skill: - Business process, As-Is/To-Be, controls, KPIs, goals: `../fsl-business/SKILL.md` …

How to install
mdr add ymm-oss/fsl/fsl-delivery@sha256:cda07c33d79727c1The line at the top of this page pins the label git:20261017.bf06ebf, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
