Every crossing of the protocol boundary is explicit.
A tool interface under exploration: a client and model on one side of an explicit protocol boundary, servers exposing tools and resources on the other, and a permission gate between them controlling which operations are allowed to cross.
01
observations
Tools as engineering boundaries
The current focus is on tool contracts, context shape, permissions, failure handling, and the line between deterministic automation and agent judgment.

Current questions
How narrow should a useful tool contract be?
Which operations need explicit human approval?
How should failures remain legible to both the agent and the person supervising it?
