Three tools with complete input schemas and descriptions, but significant quality gaps. Tool names lack action verbs (call, run_duration_test, run_times_test are weak). Descriptions are present but generic, 'Runs a benchmark test' repeats across tools without distinguishing when to use each. Parameter descriptions are adequate but lack constraints (no min/max for duration_seconds, concurrency, times). Output is unstructured raw text, not typed objects. No error recovery guidance. The 'call' tool is a low-level wrapper; run_duration_test and run_times_test are higher-level but poorly differentiated. Missing pagination, result limits, and structured response schemas.

• Rename tools with clear action verbs: 'benchmark_by_duration', 'benchmark_by_count', 'send_benchmark_request' (or similar). Distinguish in names which parameter drives the test.
• Return structured JSON with typed fields: {status_code, response_time_ms, throughput_rps, success_count, failure_count, errors: [{code, message}]}. Parse curl output server-side.
• Add min/max constraints to numeric params: duration_seconds (1 - 3600), concurrency (1 - 1000), times (1 - 100000). Document in descriptions.
• Wrap error responses with actionable guidance: 'Connection timeout after 60s. Verify the target URL is reachable and the proxy is running on 127.0.0.1:9900.'
• Add a 'headers' parameter to run_duration_test and run_times_test so users can pass custom headers without calling the low-level 'call' tool directly.
