Four tools with clear naming (verb_noun pattern) and reasonable descriptions (100-150 chars each). All tools are READ_ONLY, which is appropriate. However, input schemas lack depth: parameters have types and basic descriptions, but missing constraints (enums, ranges, patterns). Output schemas are not documented in the source. Error handling and recovery guidance are absent. Tool composition is sound (each does one thing), but parameter descriptions could be more prescriptive about formats and constraints.

• Document output schemas for all four tools. Specify field names, types, and what each field represents. Include example responses showing the structure LLMs will receive.
• Add JSON Schema constraints: min/max for 'limit' (1-100), minLength/maxLength for 'query', and pattern validation for 'session_id' (UUID format). Constraints prevent invalid LLM inputs.
• Add error handling guidance: 'If session_id is not found, returns error code 404 with message "Session not found. Try search_sessions() to find a valid session."' This teaches the LLM how to recover.
• Enhance create_handoff parameter descriptions: clarify interaction between full_history and token_budget (which takes precedence?), explain what happens if token_budget is insufficient, and document default behavior for include_memories.
• Add pagination to list_memories: accept optional 'limit' (default 20, max 100) and 'offset' parameters. Return total_count and next_offset in response. This prevents context explosion and enables browsing large memory sets.
