KalkulatorLuas is a simple geometry calculator with 4 tools. All tools have descriptions (10-60 chars, below the 50-200 char LLM-optimized baseline) and visible input schemas with typed parameters. However, descriptions are minimal and lack context about when/why to use each tool. No output schemas are documented. Tools follow a consistent naming pattern (hitung_luas_*) but lack action verbs (should be 'calculate_area_*' or 'compute_area_*'). All parameters have types and descriptions, meeting baseline requirements. No error handling, validation guidance, or recovery paths documented. The server is functional but lacks production-grade polish.

• Rename tools to follow verb_noun pattern: 'calculate_triangle_area', 'calculate_square_area', 'calculate_rectangle_area', 'calculate_trapezoid_area'. This helps LLMs infer intent from the name alone.
• Expand descriptions to 50-200 characters with context: 'Calculate the area of a triangle given base and height. Use this when the user provides two perpendicular measurements. Returns area in square units.'
• Document output schema explicitly: 'Returns {"luas": float} where luas is the calculated area in square units (same units as input).'
• Add input validation with clear error messages: 'alas must be a positive number (> 0). Received: {value}. Geometry requires positive dimensions.'
• Add parameter constraints to descriptions: 'alas: Panjang alas dari segitiga (must be > 0, in same units as tinggi).' and 'tinggi: Tinggi dari segitiga (must be > 0, perpendicular to alas).'
