All 4 tools have basic schemas and descriptions, but quality is below production baseline. Descriptions are minimal (34-72 chars, below the 194-char average for A+ tools). All tools have empty input schemas (no parameters), which is appropriate for their design but limits composability. No parameter descriptions exist (0% vs 100% baseline for A+ tools). No output schemas documented. Error handling is present but generic. Tool names follow verb_noun convention (positive), but descriptions lack WHEN/WHY context and don't explain state-modifying implications for run_io_benchmark.

• Add output schema documentation for each tool. Example for get_system_info: {"type": "object", "properties": {"os": {"type": "string"}, "cpu_cores": {"type": "integer"}, "total_ram_gb": {"type": "number"}}, "required": ["os", "cpu_cores"]}
• Expand descriptions to 150-250 characters with WHEN/WHY context. E.g., 'Runs a lightweight CPU-bound task (prime calculation up to 50,000) to measure single-threaded CPU performance. Use this to compare CPU speed across systems or detect performance regressions.'
• Add optional input parameters to benchmark tools for customization: run_cpu_benchmark(limit: integer, min=1000, max=100000, default=50000) and run_io_benchmark(file_size_mb: integer, min=1, max=500, default=50). Document each parameter with type, range, and purpose.
• Declare run_io_benchmark as state-modifying in its description: 'Measures sequential file read/write speeds over a 50MB payload. Creates and deletes a temporary file (io_test_benchmark.tmp) during execution.'
• Enhance error responses with recovery guidance. E.g., instead of '{"error": "I/O Benchmark failed: ..."}', return '{"error": "I/O Benchmark failed: Permission denied. Ensure the working directory is writable. Retry after checking disk space and permissions."}'
