Four tools with clear verb-noun naming (list_, read_, search_, get_) and READ_ONLY risk classification. All have descriptions (34 - 194 chars, within baseline range). Input schemas present with type declarations. However, parameter descriptions are minimal or absent, most params lack actionable guidance on format, constraints, or dependencies. Output schemas are not documented. Error handling is basic (FileNotFoundError, RuntimeError) with no recovery guidance. No tool annotations (readOnlyHint, idempotentHint). Composition is sound (each tool does one thing), but descriptions could be more LLM-optimized per pattern:tool-description baseline (10 - 1024 chars, ideally 50 - 200).

• Add detailed parameter descriptions: 'relative_path: Relative path to document within knowledge base (case-sensitive, forward slashes, e.g., docs/guide.md or notebooks/analysis.ipynb).'
• Document output schemas in tool docstrings. E.g., list_documents returns [{path: string, size_bytes: int}]; read_document returns {content: string, format: 'markdown'|'notebook'}.
• Enhance error messages with recovery hints: 'File not found: docs/guide.md. Try search_documents(query="guide") to find similar documents.'
• Add readOnlyHint annotation to all four tools in schema to signal idempotency and enable client-side caching.
• Constrain search_documents query: add description 'Search query (case-insensitive substring match on file paths and content; supports * wildcard). Returns up to 50 results.' and document result limit in tool description.
