Scored across 19 tools
Most tools have distinct purposes, but pairs like loop_optimization/loop_regression and start_optimization_session/loop_optimization could be confused. Descriptions help differentiate, but the distinction between single-pass and loop modes might not be immediately clear.
All tool names follow a consistent verb_noun pattern in snake_case (e.g., add_test_cases, set_system_prompt). No mixing of conventions or ambiguous names.
19 tools cover the full prompt lab workflow without excess. Each tool addresses a distinct step in setup, testing, optimization, and management, making the count appropriate for the server's scope.
The tool set covers the main workflow end-to-end, but lacks granular control like editing or deleting individual test cases or canceling loops. Minor gaps, but core functionality is present.
