Integration with Other Skills

MCP skills commonly combine with:

API skills (discover-api):

MCP servers wrapping REST or GraphQL APIs
Authentication for MCP tool backends

Testing skills (discover-testing):

Comprehensive test strategies
Contract testing patterns

Infrastructure skills (discover-infra, discover-cloud):

Deploying MCP servers
Scaling HTTP transports

Progressive Loading

This gateway skill (~170 lines, ~1.5K tokens) enables progressive loading:

Level 1: Gateway loads automatically (you're here now)
Level 2: Load category INDEX.md (~2.5K tokens) for full overview
Level 3: Load specific skills (~2-3K tokens each) as needed

Total context: 1.5K + 2.5K + skill(s) = 4-8K tokens vs 12K+ for everything.
