2.8Key Takeaway

The elegance of the skill system is that it adds zero new infrastructure. No servers, no APIs, no protocols. Just a markdown file that gets injected into conversation context at the right time. The agent does the rest with tools it already has (Bash, Read, Write).

This is why skills are so much lighter than MCP: MCP requires a running server process, a protocol handshake, tool schema exchange, and persistent state management. A skill is literally a file.
