proyecto26/system-design-skillsSkill
This skill should be used when the user needs to "design the API", do "endpoint design", pin down a "request/response shape", choose a "pagination" strategy (cursor vs offset), add an "idempotency key" to a write, plan "API versioning", an "error contract", or pick between "REST vs gRPC vs GraphQL" or "WebSocket vs polling". Use it whenever a design has reached the interface — the concrete request, response, primary access path, and how clients page, retry, and version — even if the user only said "the boxes talk to each other".
Why this score
This repo hosts 10 skills, so its 93 stars are split between them (about 9 each) for scoring.
Popularity score: 48/100 from public GitHub signals only. It shows how widely used and maintained this is, not how well it works. Not included yet: the fake-star check. The security scan is shown separately and doesn't change the score. How we rank
Security
Scanned Nov 4, 2026 at commit a70772efb956, with Cisco's open-source skill-scanner.
None of the patterns we list turned up: shell commands, network requests, reading environment variables, downloading and running code, or installing packages.
A scan lists patterns in the code. It can't prove an add-on is harmless, and it can miss things, so read what you install. How we scan
