Human Memory presents well-structured tool definitions with complete schemas and clear descriptions. All 6 tools have explicit JSON Schema with typed properties and required fields. Descriptions are concise (50-150 chars) and action-oriented. Naming follows verb_noun convention (store, retrieve, list, search, briefing). Key strengths: batch operations, pagination support, scope-based access control. Weaknesses: output schemas are not documented (LLMs cannot predict response structure); no error recovery guidance; no tool annotations (readOnlyHint/destructiveHint); parameter descriptions lack format/constraint details (e.g., key format 'category/project/artifact' is in tool description, not param description).

• Add output schema documentation to each tool definition. Example for human_memory_retrieve: 'Returns: {key: string, value: object, metadata: object, revision: integer, created_at: ISO8601, updated_at: ISO8601}'
• Add tool annotations: mark human_memory_store as destructiveHint=true (overwrites), human_memory_retrieve/list/search/briefing as readOnlyHint=true, human_memory_store with if_revision as idempotentHint=true
• Enhance parameter descriptions with format constraints. For 'key' param: 'Document key in format category/project/artifact (e.g., travel/miami/plan). Each segment 1-50 alphanumeric chars.'
• Add error recovery hints to descriptions. For human_memory_retrieve: 'If key not found, call human_memory_list with prefix to discover available keys.'
• Add min/max constraints to schema for numeric params: limit: {type: integer, minimum: 1, maximum: 200, default: 50}
