Each tool has a distinct role: reading, formatting as prompt, event-driven updates, fine-grained injection, settling, explaining causes, and history. The only mild overlap is between state_read and state_prompt, but the descriptions clarify that one is raw state and the other is a ready-to-use prompt fragment.

All tools consistently use the state_ prefix and lowercase naming. Some entries use nouns or adverbs instead of verbs, but the pattern is predictable and easy to navigate.

Seven tools is a well-scoped size for this state-management domain. Each tool provides a meaningful capability without unnecessary bloat or missing core functionality.

The set covers reading state, using it in prompts, updating via events, fine-grained adjustment, settling, causal tracing, and viewing history. A hard reset or history-clearing operation is absent, but the deliberate design avoids it and the core lifecycle is well covered.
