Interesting that this came out of 500 agents in production. The hardest part I've seen with agent tool calls is handling partial failures gracefully — the tool returns something but it's incomplete or stale. Do you bake retry/fallback logic into the framework itself or leave that to individual tool implementations?

Unkey handles this well — single API call at the edge that does both key verification and rate limiting in sub-millisecond. Avoids the D1 read-modify-write race condition entirely since the rate limit state lives in their distributed system, not your worker's database.
