10 tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. All tools have descriptions (10-100+ chars), and input schemas are present with type definitions. However, most parameter descriptions are minimal (1-2 words), output schemas are not documented, and error handling guidance is absent. No tool annotations (readOnlyHint/destructiveHint). Naming is verb-forward but generic (store, retrieve, query). This is a typical community server, functional but not production-grade.

• Add output schema documentation to every tool. E.g., retrieve() should document: 'Returns list of [fact: string, weight: float] pairs, sorted by weight descending. Max length = top_k parameter.'
• Expand parameter descriptions to 50-100 chars. E.g., 'query: The search query string. Encoded into a vector and matched against stored facts using cosine similarity.' instead of 'The query string'.
• Add tool annotations via FastMCP. Mark store/store_negative/save/load with destructiveHint=true; mark retrieve/query/list_facts/working_memory_status with readOnlyHint=true.
• Clarify the semantic difference between query(), query_or_none(), and retrieve() in their descriptions. E.g., 'query: Returns the single best-matching fact (always succeeds). Use when you need one answer. retrieve: Returns top-k facts with weights. Use for ranked results or when you need alternatives.'
• Add error handling to load() and save(). Return structured errors like {'error': 'File not found', 'path': '...', 'suggestion': 'Check HOPFIELD_STATE_PATH environment variable'} instead of raising exceptions.
