Facilitate system design by classifying mode, depth, and surface independently; scoping journeys; estimating only decision-relevant quantities; tracing logical flows before physical binding; and selecting risk-driven views and deep dives. Use for system design sessions and reviews.
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
# System Design Methodology ## **Priority: P0 (CRITICAL)** Classify work mode, depth, and system surface independently. Load only the relevant skill siblings: data-architecture for consequential data/state flows, mobile-client for mobile/client or SDK/library concerns, and diagramming only when a view is selected. Backend, mobile/client, SDK/library, and full-stack are surfaces; none is a mode. ## Phase 0 - Classify - State mode (new design | review existing | interview practice), depth (quick | full), and surface (backend | mobile/client | SDK/library | full stack). A mixed system may name multiple surfaces. - Quick sketches use explicit assumptions and skip confirmation gates; full sessions follow the per-phase exit predicates in the [four-phase process](references/four-phase-process.md) and confirm consequential decisions. Escalate quick to full for hard constraints or irreversible choices; an unresolved material decision prevents a readiness claim. - Interview practice follows [interview coaching](../system-design-interview-coaching/SKILL.md); production review/design follows this process. ## Phase 1 - Intake …

How to install
mdr add hoangnguyen0403/agent-skills-standard/system-design-methodology@sha256:4f58738b1a2b7bb4The line at the top of this page pins the label git:20261021.8da3953, 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.
