Significant gaps across naming, descriptions, and schemas. Tool names lack consistent verb prefixes (e.g., 'classify_solids_for_meshing' vs 'execute_tcl_gui'). Descriptions are present but generic, most lack context on WHEN to use each tool or what prerequisites exist. Parameter descriptions are minimal; many lack type constraints or ranges. No documented output schemas. Error handling is absent, no guidance on recovery or retry logic. The server exposes domain-specific complexity (Tcl scripts, socket connections, file paths) without abstracting it into user-friendly operations.

• Document output schemas for all 11 tools. Specify returned fields, types, and whether results are paginated. Example: 'Returns {success: bool, mesh_id: string, element_count: int, quality_metrics: {aspect_ratio: float, skew: float}}'.
• Enhance descriptions with WHEN/WHY context. For each generate_*_tcl tool, add: 'Use this when [geometry condition]. Prefer over [alternative] because [reason]. Falls back to tetra if [failure condition].'
• Add parameter constraints to all numeric fields. Specify units (mm), ranges (0.5 - 1.5), and defaults. Example: 'element_size_min (float, mm, default 0.5, range 0.1 - 10): Minimum element size for surface mesh.'
• Implement error handling with recovery guidance. For execute_tcl_gui and run_hmbatch_meshing, document timeout behavior, partial failure modes, and retry eligibility. Example: 'If socket timeout occurs, verify HyperMesh listener is running on [host]:[port] and retry.'
• Standardize tool naming to verb_noun pattern. Rename 'generate_guarded_drag_hex_tcl' → 'generate_drag_hex_script', 'classify_solids_for_meshing' → 'classify_solids', 'create_gui_listener_tcl' → 'create_gui_listener'. This improves LLM parsing and reduces ambiguity.
