Enforce end-to-end product quality for Nebula interface, mobile, LAN, chat/session lifecycle, provider, harness, workspace, and other operator-visible changes. Use whenever implementing, fixing, reviewing, or claiming completion of a workflow that an operator reaches through the Nebula UI, especially changes under ui/, API-to-UI integrations, persistence/reconnect behavior, responsive layouts, or browser security boundaries.
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
# Nebula Product Quality Treat each change as an operator workflow, not an isolated component. Establish the behavioral contract before editing, test it through the real entry point, and do not claim completion without evidence for every applicable gate. Apply the repository's `docs/design/interface-principles.md` alongside these gates: icon-first secondary controls, minimal copy, subtle styling and accessible actions. ## 1. Establish the contract Before implementation: 1. Name the operator journey and its real entry point. 2. List the state owners involved: URL, browser storage, React state, Core database, provider or harness session, workspace, and connection state. 3. Write observable invariants. Include persistence and responsive invariants when relevant, such as “the selected chat and transcript survive reload” or “the focused composer remains inside the visual viewport.” 4. Enumerate the lifecycle: discover, create, select, use, stream, interrupt, background, reconnect, refresh, fork or retry, delete or revoke. 5. Mark each lifecycle step applicable, not applicable with a reason, or required. …

How to install
mdr add berylliumsec/nebula/nebula-product-quality@sha256:e2042f53cacfba95The line at the top of this page pins the label git:20260909.241962b, 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.
