SemanDoc has 15 tools with basic schema definitions and descriptions, but exhibits significant gaps in naming clarity, parameter documentation, and output schema specification. Tool names follow action-verb conventions (create_, delete_, get_, search_, list_), but several are ambiguous or lack proper parameter type constraints. Descriptions exist but are often generic (10-80 chars) and fail to explain WHEN to use a tool, what happens on invocation, or what fields are returned. Input schemas are present but incomplete: parameters lack required type definitions in several tools (e.g., update_api_key_activation's is_active parameter type is documented in description but may not be formally typed). No output schemas are documented, making it impossible for LLMs to plan downstream tool calls. Error handling is minimal, most tools return generic HTTP 500 errors without recovery guidance. Security concerns exist: API key operations expose key_id and is_active in URLs/parameters without clear permission gating. The webhook tool (webhook_create_document) is particularly problematic, it bypasses standard metadata structure but lacks description of its unique purpose.

• Document output schema for every tool. Specify which fields are returned, their types, and required/optional status. Example for create_document: 'Returns {document_id: string, created_at: ISO8601, content: string, metadata: {id, tags, categories}}'.
• Add 20-50 char descriptions for tools with minimal docstrings (get_document_stats, export_documents, force_save_vector_store, rebuild_index). Explain what the tool does, when to call it, and what it returns. Example: 'Rebuild the semantic search index after bulk document deletions to reclaim storage and improve search latency.'
• Replace generic HTTP 500 errors with actionable error messages. When delete_document fails with 'document not found', return: 'Document "doc-123" not found. Try search_documents(query="...") to find documents by content.'
• Remove or consolidate webhook_create_document. If it is truly needed, rename to 'create_document_simple' and add a description explaining the simplified metadata model and when to use it instead of create_document.
• Add confirmation/dry-run support for destructive tools (delete_document, remove_api_key). Implement a 'dry_run' parameter that returns what would be deleted without committing, letting agents preview before executing.
• Document parameter constraints explicitly. For document_id: 'UUID format (36 chars, hyphens at positions 8, 13, 18, 23)'. For score_threshold: 'Range [0.0, 1.0], default 0.5'. For tags: 'Array of 1-50 strings, each 1-100 chars, no special characters.'
• Standardize pagination: all list/search tools should return total_count and next_cursor (if paginated). Ensure skip/limit defaults (skip=0, limit=20) prevent accidental large result sets.
