SlitherMCP has 7 tools with reasonable naming (verb_noun pattern) and descriptions, but critical gaps in schema completeness, parameter documentation, and error handling. All tools have descriptions (10-200 chars, within baseline), but input schemas lack proper type definitions for optional parameters. No output schemas documented. Error handling is minimal, tools return raw strings without guidance for recovery. Parameter descriptions exist but lack constraints (enums, ranges, formats). The codebase shows incomplete implementations (e.g., slither_analyze_dependencies cuts off mid-function), suggesting unfinished work.

• Document output schemas for all tools. Example: slither_analyze should return {vulnerabilities: [{type: string, description: string, severity: string}], contract_count: number, summary: string}.
• Add enum constraints to parameters. slither_check_erc should define erc_standard as enum: ['ERC20', 'ERC721', 'ERC1155', ...]. Replace free-form strings with validated options.
• Implement structured error responses. Instead of 'No paths found', return {status: 'not_found', message: 'No paths to target_function found', suggestion: 'Verify function exists and is called internally'}.
• Complete the slither_analyze_dependencies implementation. The function is truncated in the provided source.
• Add parameter constraints to descriptions. Example: contract_path should note 'Must be a valid file path or directory containing .sol files' and contract_name should clarify 'Must match a contract name in the analyzed files'.
