What strikes me is that MCP vs Skills vs Bespoke are all answers to ‘how does an agent use a known capability.’ How does it find one (?) is where I’m experimenting.

Discovery and payment at the agent layer still feels like the missing primitive.

Also (food for thought) the local LLM angle keeps getting underweighted in many discussions. For someone running Gemma 4 locally, there’s no tool layer at all by default. Different problem than the cloud agent angle.
