Five tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Tool names follow verb_noun convention (initialize_, search_, get_, list_). Descriptions exist but are brief (avg ~60 chars, below 194-char baseline). Most parameters lack descriptions entirely. No output schemas documented. Error handling absent. Security concerns: file_path parameter in get_file_content is untrusted input with no path traversal validation mentioned. initialize_knowledge_base lacks confirmation/dry-run pattern for destructive reindex operation.

• Document output schema for each tool. Example: search_knowledge_base returns {results: [{file_path: string, text_content: string, similarity_score: number}], total_count: number}.
• Add parameter descriptions with constraints. Example: 'limit' → 'Maximum results to return (1-100, default 5)'; 'threshold' → 'Cosine similarity threshold 0.0-1.0 (default 0.5)'.
• Implement path traversal validation in get_file_content. Resolve file_path relative to PROJECT_ROOT and reject paths containing '..' or absolute paths outside project.
• Add confirmation pattern to initialize_knowledge_base. Return {status: 'confirmation_required', message: 'Reindex will delete existing embeddings. Confirm?'} and require explicit confirm=true parameter.
• Document error responses with recovery guidance. Example: 'File not found at <path>. Ensure file is within PROJECT_ROOT and has an allowed extension (.js, .ts, etc.)'
