Guide system design work. Use for requirements, APIs, data models, service.
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 Use this skill when working on system design tasks. ## Workflow - Clarify functional requirements, non-functional requirements, constraints, and failure modes before drawing components. - Model data, interfaces, trust boundaries, operations, observability, and migration path. - Prefer diagrams and ADRs that match the repo's architecture documentation conventions. ## Boundaries - Inspect the target repository before making changes. - Prefer existing project patterns, declared package managers, and documented validation commands. - Do not expose secrets, credentials, private user data, or production account identifiers in source, examples, or logs. - When external APIs or current vendor behavior matter, verify against official docs before implementation. ## Provenance - Source: `https://github.com/anthropics/knowledge-work-plugins` - Ref: `main` at `a84404cb0156a15702c9ecf4d16051346cacce49` - Source path: `engineering/skills/system-design/SKILL.md` - License classification: `Apache-2.0` - Source SHA-256: `8f28eca99f2208872fc2483fcc93326b628f4f73116e91309a95e05da86a0ab5`

How to install
mdr add cruxexperts/localsetup/ls-system-design-tradeoffs@sha256:dd477e88737d5bb3The line at the top of this page pins the label v1.0, 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.
