TexasSolver MCP has solid foundational structure with 5 tools featuring proper JSON Schema definitions and reasonable descriptions. All tools have clear naming conventions (verb_noun pattern: run_solver, load_range, list_ranges, build_game_tree_config, list_outputs) and explicit schemas with required fields. However, there are meaningful gaps: parameter descriptions lack constraint details (ranges, formats, patterns), output schemas are not formally documented, error handling is generic without recovery guidance, and several parameters omit descriptions. The tool names follow arcade.dev conventions but descriptions could be more LLM-optimized per the 50-200 char baseline.

• Document output schema for each tool in the tool definition. Example for list_outputs: return {items: [{filename: string, created_at: ISO8601, size_bytes: number, path: string}], total: number, next_cursor?: string}.
• Add numeric constraints to pot, effective_stack, and limit parameters. Example: 'pot (number, ≥0.1, ≤10000): Starting pot size in big blinds'.
• Define nested schemas for bet_sizes and solver_config as JSON Schema objects with explicit properties. Map them to the TexasSolver CLI documentation.
• Enhance error responses with classification and recovery paths. Example: 'Solver timeout after 30s (retryable). Try: reduce effective_stack, limit range complexity, or increase timeout via solver_config.max_iterations'.
• Add a discovery section to tool descriptions linking related tools. Example in run_solver: 'First, use list_ranges() to discover available preflop ranges, then call load_range() to parse a custom range file.'
• Document idempotence and side effects explicitly. Example for run_solver: 'Side effect: writes output file to data/{timestamp}-{output_name}.json. Idempotent if output_name is fixed; non-idempotent with auto-generated names.'
• Replace free-form parameter descriptions with structured format: name (type, constraints): description. Example: 'board (string, format: "As,Kh,Qd" or empty): Community cards in suit-rank format, or empty for preflop.'
• Add minimum and maximum constraints to limit parameter in list_outputs and clarify pagination behavior if results exceed limit.
