Nine tools with complete input schemas and descriptions, but significant quality gaps. Naming is verb-based (generate_*, run_*, create_*, query_*, compute_*) but descriptions are terse (avg 80 chars, well below 194-char baseline). Parameters lack type specificity, many accept generic 'object' or 'string' without constraints, enums, or format guidance. No output schemas documented. No error handling guidance. No parameter validation rules stated. Tools like generate_code and generate_schema accept free-form 'language' and 'format' strings without enums, inviting hallucinated values. No security considerations visible (no permission gates, audit trails, or secret injection patterns). Composition is reasonable (each tool has one responsibility), but chaining is weak, no IDs returned to enable downstream calls.

• Add output schemas to all 9 tools. Document return type (object, array, string), key fields, and their types. E.g., generate_edge_cases should return {type: 'array', items: {type: 'object', properties: {value, description}}}.
• Replace free-form 'language' and 'format' parameters with enums. Change generate_code.language to enum: ['python', 'javascript', 'typescript', 'go', 'rust']. Remove 'or other'. Same for generate_schema.format and generate_tests.framework.
• Expand tool descriptions to 150 - 250 chars. Add WHEN to use, prerequisites, and what the output contains. E.g., 'Generate edge cases for a given type to test boundary conditions. Returns array of {value, description} objects. Use before run_benchmark to create comprehensive test suites.'
• Add error handling guidance. Document expected errors (e.g., 'Invalid language: must be one of python, javascript, typescript, go, rust') and recovery steps. E.g., 'If language is unsupported, try a similar language or ask the user.'
• Add parameter validation rules in descriptions. E.g., 'count must be 1 - 100' for generate_tests. 'nodes must be non-empty array' for create_graph. Use JSON Schema minItems, maxItems, pattern, enum constraints alongside descriptions.
