This toolkit exhibits severe definition quality gaps across 24 tools. Most tools lack proper input schemas (only 8 of 24 have visible schema definitions in source). Descriptions are present but generic and often under 50 characters. Parameter descriptions are sparse or missing entirely. No output schemas documented. Error handling is minimal. Tools span multiple languages (TypeScript, Python) with inconsistent patterns. The 'eval' tool (execute arbitrary JavaScript) and 'run_command' tool (shell execution) are destructive without confirmation patterns. Duplicate tool names ('search' appears 3 times, 'stock_quote' and 'get_quote' are near-duplicates) violate composition principles.

• Rename duplicate tools: consolidate 'search' variants into 'search_exa', 'search_cognee', 'search_cognee_memory'; rename 'stock_quote' and 'get_quote' to 'get_stock_quote' and 'search_stock_symbols' respectively.
• Add confirmation/dry-run pattern to 'eval' and 'run_command'. Require explicit confirmation before executing arbitrary code or shell commands. Return a preview of what will execute and ask for approval.
• Document output schemas for all 24 tools. Specify field names, types, and whether results are paginated. Include example responses in tool metadata.
• Add input validation and error guidance. For 'run_command', validate against a whitelist of safe commands. For 'eval', restrict to read-only operations. Return actionable error messages: 'Invalid stock symbol: got "XYZ", try search_stock_symbols("company name") first.'
• Implement server-side secret injection. Move API keys to a secure vault or environment-only config. Never expose them in tool parameters or responses. Log which tool was called, not with which credentials.
