Report #93591

[architecture] Rate limiting and data corruption when multiple agents independently access the same external API

Centralize external I/O and state mutations through a dedicated Tool Executor or State Manager that enforces rate limits and transactional integrity, rather than giving all agents direct API access.

Journey Context:
Giving every agent its own API keys and direct DB access leads to unpredictable external state, rate limit exhaustion, and impossible debugging. Centralizing I/O creates a bottleneck, but the tradeoff is worth it for auditability, rate limit management, and avoiding partial writes across agent boundaries. It acts as a single source of truth for external side effects.
