GhidraMCP exhibits significant definition quality gaps. Tool descriptions are present but generic (avg ~80 chars, below 194-char baseline). Most parameters lack type definitions in visible schemas, only function_name and address appear typed. No output schemas documented. Error handling is absent. Tool naming follows verb_noun convention (get_, list_, find_) but lacks specificity for distinguishing similar tools (get_program_info vs get_metadata are duplicates). No parameter descriptions visible for most tools. Security-sensitive operations (decompile, disassemble) lack permission gates or dry-run patterns. Composition is reasonable (single responsibility per tool) but chaining support unclear, no evidence that tool outputs include IDs needed for downstream calls.

• Merge get_program_info and get_metadata into a single get_program_metadata tool with clear documentation of returned fields (name, entry_point, architecture, base_address, etc.).
• Document output schemas for all tools in JSON Schema format. Example: list_functions should return {type: 'object', properties: {functions: {type: 'array', items: {type: 'object', properties: {name: {type: 'string'}, address: {type: 'string'}, size: {type: 'integer'}}}, total: {type: 'integer'}}}.
• Add parameter descriptions and constraints: find_undocumented_functions.pattern should specify 'regex pattern or literal string (default: FUN_)'; list_functions.limit should specify 'max 1000, default 50'.
• Add error handling guidance: decompile should return 'Decompilation timeout after 30s. Try a smaller function or call disassemble for assembly-only view.' on timeout.
• Implement permission checks: gate decompile and disassemble behind a 'read:reverse_engineering' scope; require explicit confirmation for force_refresh=true operations.
