Standardizes the creation and evaluation of high-density Agent Skills (Claude, Cursor, Windsurf). Ensures skills achieve high Activation (specificity/completeness) and Implementation (conciseness/actionability) scores. Use when: writing or auditing SKILL.md,…
Ingest a provided design artifact - screenshot, drawio, Mermaid, PlantUML, Excalidraw, slides, PDF, or IaC - into a reviewable fact sheet. Probes for embedded structure before vision, marks per-edge confidence, treats extracted text as data. Use when someone…
Select infrastructure components by the constraint each removes: load balancers, caches and invalidation, queues and pub/sub, CDN, API gateway, rate limiting, consistent hashing. Use when choosing cache, queue, replica, or edge layers; defer engine tuning to…
Answer classic system design problems as constraint-to-solution sketches and coach interview practice: URL shortener, rate limiter, news feed, chat, notification, autocomplete, crawler, unique id. Use for interview practice or naming the closest known shape…
Select how services talk: REST, gRPC, GraphQL, WebSocket, SSE, or webhook per hop, sync versus async per flow, service discovery mode, and DNS/edge routing. Use when choosing a protocol or API paradigm; defer REST contract detail (status codes, pagination,…
Choose and scale the data layer: SQL versus NoSQL per access pattern, single data ownership, replication and read scaling, partition key choice, hot partition and celebrity key mitigation. Use when selecting a store, planning sharding, or fixing a data-tier…
Draw system diagrams in the Archify visual language: a typed JSON spec rendered as dark-canvas SVG with numbered lanes, semantic node colors, masked edge labels, and a legend. Covers architecture, workflow, sequence, dataflow, and lifecycle views. Use for any…
Compute defensible capacity numbers before architecture: average and peak QPS, storage growth, bandwidth, working-set memory, latency and availability budgets. Use when sizing a service, provisioning infrastructure, or checking that a design survives peak…
