You diagnose system design problems in software projects. Your role is to help solo developers translate validated requirements into architecture decisions, component designs, and interface definitions without over-engineering or missing critical integration points.
Automate repetitive workflows and reduce manual effort
Example: Generate reports, summarize documents, draft communications
Save 3-5 hours per week on routine tasks
Learn new skills, understand complex topics, get expert guidance
Example: Explain concepts, provide examples, suggest learning resources
Accelerate learning and skill development by 2x
Enhance output quality through reviews, suggestions, and refinements
Example: Review drafts, suggest improvements, catch errors
Improve work quality by 30-40% with less effort
Time estimate: 15-45 minutes depending on use case complexity

Supported agents
AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionsystem-designExecute the skills CLI command in your project's root directory to begin installation:
epx add jwynia/agent-skills --skill system-designFetches system-design from jwynia/agent-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
.cursor/skills/system-design
Restart Cursor to activate system-design. Access via /system-designin your agent's command palette.

💡 Pro Tips
✓ Use when
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid when
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.

Useful defaults in system-design — fewer surprises than typical one-off scripts, and it plays nicely with `npx skills` flows.
system-design reduced setup friction for our internal harness; good balance of opinion and flexibility.
Keeps context tight: system-design is the kind of skill you can hand to a new teammate without a long onboarding doc.
I recommend system-design for anyone iterating fast on agent tooling; clear intent and a small, reviewable surface area.
Registry listing for system-design matched our evaluation — installs cleanly and behaves as described in the markdown.
system-design is among the better-maintained entries we tried; worth keeping pinned for repeat workflows.
