Server has 7 tools with significant definition gaps. Meta-tools (kicad_discover, kicad_load_toolset, etc.) have minimal descriptions (10-50 chars) and lack parameter details. kicad_analysis_tools is a monolithic 14-parameter tool combining SI, PI, EMC, and design lint operations, violates single-responsibility principle. Most tools lack output schema documentation. No error handling guidance visible. Tool names follow verb_noun pattern but descriptions are too terse for LLM selection.

• Split kicad_analysis_tools into 7 separate tools: si_trace_width_for_impedance, si_diff_pair_impedance, pi_voltage_drop, emc_check_return_paths, design_lint, sch_pcb_crossref, board_size_estimate. Each tool does one thing; LLM composes them.
• Expand meta-tool descriptions to 100-200 chars. Example: 'Discover available toolsets and their descriptions. Call this first to see what categories are available (board, schematic, analysis, etc.), then use kicad_load_toolset to enable specific toolsets for your task.'
• Document output schemas for all tools. Example for kicad_discover: 'Returns {toolsets: [{name: string, description: string, routers: string[], always_loaded: boolean}], current_mode: string, loaded_toolsets: string[]}'.
• Add enum constraint to kicad_set_profile 'name' parameter. Replace 'etc.' with explicit enum in schema: ['read-only', 'build', 'manufacturing', 'expert', 'full'].
• Add error handling guidance to tool descriptions. Example: 'If toolset not found, call kicad_discover to see available toolsets. If operation fails, check kicad_get_capabilities to verify server state.'
