Feature	Skills	Prompts	Projects	Subagents	MCP
What it provides	Procedural knowledge	Moment-to-moment instructions	Background knowledge	Task delegation	Tool connectivity
Persistence	Across conversations	Single conversation	Within project	Across sessions	Continuous connection
Contains	Instructions + code + assets	Natural language	Documents + context	Full agent logic	Tool definitions
When it loads	Dynamically, as needed	Each turn	Always in project	When invoked	Always available
Can include code	Yes	No	No	Yes	Yes
Best for	Specialized expertise	Quick requests	Centralized context	Specialized tasks	Data access

Aspect	Classic Three-Tier	Spine-Leaf
Structure	Core → Distribution → Access layers	Two layers: Spine (core) and Leaf (access) switches
Traffic Pattern	Optimized for north-south (client-to-server)	Optimized for east-west (server-to-server)
Latency	Variable; depends on path through tiers	Predictable; any server is the same number of hops away
Scalability	Limited; adding capacity is complex	Horizontal; simply add more spine or leaf switches
Complexity	Simpler for small deployments	Better suited for large-scale data centers
Use Case	Traditional enterprise; campus networks	Modern data centers; cloud environments
