Explain Systems Design Concept
Explain a systems design concept in practical, developer-friendly terms.
Arguments
$ARGUMENTS - The concept to explain (e.g., "CAP theorem", "sharding", "circuit breaker", "load balancing")
Workflow
Identify the concept category to load the appropriate skill:
- Interview methodology →
design-interview-methodology
- Estimation/capacity →
estimation-techniques
- Quality attributes/NFRs →
quality-attributes-taxonomy
- Future phases: distributed systems, scalability, cloud-native
Provide a practical explanation that:
- Explains what it is in plain terms
- Shows why it matters for system design
- Gives concrete examples when possible
- Discusses trade-offs and when to use it
- Links to related concepts
Include reference examples where helpful:
- Back-of-envelope calculations for scale concepts
- Decision criteria for pattern selection
- Real-world analogies for complex concepts
Example Usage
/sd:explain CAP theorem
/sd:explain sharding
/sd:explain circuit breaker
/sd:explain back-of-envelope
/sd:explain load balancing
/sd:explain eventual consistency
/sd:explain latency vs throughput
/sd:explain quality attributes
/sd:explain scalability
/sd:explain the "-ilities"
