Single tool with severe definition gaps. Tool name 'execute_skill_action' is generic and violates verb_noun clarity (pattern:tool). Description is 60 chars, below the 10-1024 baseline and lacks WHAT/WHEN/WHY context. Input schema present but parameters lack descriptions entirely (critical violation of pattern:tool-description). No output schema documented. No error handling guidance. Tool appears to be a mock/stub (client.py returns hardcoded values) rather than a real implementation.

• Rename tool to 'compute_quantized_matrix_multiplication' or 'execute_quantized_tensor_operation' to clearly signal the action and domain.
• Expand tool description to 100-200 chars: 'Executes quantized tensor matrix multiplication using SIMD acceleration. Accepts batch size, quantization scheme (GGML_TYPE_Q4_K, GGML_TYPE_Q8_0), and SIMD instruction set (AVX512_VNNI_AMX, ARM_NEON_DOTPROD). Returns throughput (GFLOPS), memory bandwidth utilization, and cache miss rate.'
• Add descriptions to all parameters: token_batch_size='Number of tokens to process per batch (1-1024, default 32)', quantization_scheme='Quantization format: GGML_TYPE_Q4_K (4-bit), GGML_TYPE_Q8_0 (8-bit), etc.', simd_instruction_set='CPU SIMD extension: AVX512_VNNI_AMX (Intel), ARM_NEON_DOTPROD (ARM), etc.'
• Document output schema with field types and descriptions: kernel_execution_id (string), quantization (string), simd_architecture (string), gigaflops_throughput (number), memory_bandwidth_utilization_pct (number 0-100), cache_miss_rate_pct (number 0-100), zero_runtime_dependency_pure_c_compatible (boolean).
• Implement actual SIMD computation logic or clearly mark this as a reference/mock implementation. Add error handling for invalid quantization schemes and SIMD instruction sets with recovery guidance.
