Server has 10 tools with basic naming and descriptions, but significant gaps in schema completeness and parameter documentation. Most tools lack visible input schemas in the provided source code. Descriptions are present but generic (avg ~80 chars, below 194-char baseline). No parameter-level descriptions visible for most tools. Error handling and output schemas are not documented. Only memory_save, memory_recall, and memory_approve show explicit schema definitions; others are inferred from file references without visible implementation details.

• Add explicit JSON Schema definitions to all 10 tools. For memory_summarize, session_digest, memory_compact, memory_update, memory_delete, topic_lookup, and memory_policy, define input properties with type, description, and constraints (e.g., required fields, enums, min/max for numeric params).
• Expand tool descriptions to 100-200 chars. Include WHAT the tool does, WHEN to use it (vs similar tools), and what it returns. Example: 'Summarize a conversation session into a concise memory record. Use this instead of memory_save when a session contains multiple candidate memories. Returns a memory_id and summary text.'
• Add parameter-level descriptions for all inputs. For memory_update, document what fields can be updated and constraints. For memory_approve, clarify the difference between 'list', 'approve', and 'dismiss' actions and when each is appropriate.
• Document output schemas for all tools. Specify return type (object, array, string), required fields, and field types. Include IDs and references needed for chaining (e.g., if memory_recall returns memories, include memory_id so memory_update can reference them).
• Add error handling guidance. For destructive tools (memory_delete), document the error cases (memory not found, permission denied) and recovery steps. For write tools, clarify which errors are retryable and which require user intervention.
