Server has 11 tools with complete input schemas and descriptions, but quality is inconsistent. Tool names follow verb_noun convention well (list_collections, search_collection, vector_search). Descriptions are present but often generic (10-50 chars for many tools), lacking context on WHEN to use each tool or dependencies between them. Parameters have types and basic descriptions, but lack constraints (enums, ranges, patterns). No output schemas documented. Error handling is minimal, exceptions are caught but error messages are generic ('Search failed', 'Query failed'). No guidance on retryability, user-fixable vs fatal errors, or recovery steps. Destructive tools (delete_entities) lack confirmation patterns. Security: no secrets exposed as params (good), but no permission gates or audit trail declarations.

• Document output schemas for all tools. E.g., search_collection returns [{id: int, distance: float, ...fields}]. Include field types and meanings.
• Enhance descriptions to disambiguate similar tools. E.g., 'Full-text BM25 search on sparse text fields. Use for keyword matching. For semantic similarity, use vector_search or hybrid_search.'
• Add enum constraints to metric_type: {enum: ['COSINE', 'L2', 'IP']} in schema. Remove free-form string acceptance.
• Implement confirmation pattern for delete_entities: add a 'dry_run' parameter or require explicit 'confirm=true' flag. Return affected count before deletion.
• Improve error messages with actionable guidance. E.g., 'Collection not found. Available collections: [list]. Did you mean one of these?' or 'Invalid filter_expr syntax. Expected: field_name operator value (e.g., id > 10).'
