Show HN: MCP Isn't Dead. You're Just Using It Wrong

The lazy-loading abilities pattern makes a lot of sense for context bloat. But I'm curious about the practical middle ground? have you found that agents reliably know when to call load_ability vs trying to work with what they already have? In my experience the hardest part of tool use isn't having tools available, it's getting the model to pick the right one at the right time. What's been your experience?
