27 tools with complete input schemas and descriptions. Naming follows verb_noun convention well (read_file, write_file, run_command). Descriptions average ~80 chars, meeting baseline minimums but lacking LLM-optimized context (target 50-200 chars per pattern:tool-description). Parameters have types and descriptions. Critical gaps: no output schemas documented, no error handling guidance, no pagination for list tools, no dry-run/confirmation for destructive ops (delete_file, delete_directory, run_command). Missing tool annotations (readOnlyHint, destructiveHint). Composition is sound, each tool has single responsibility. Security concern: run_command accepts arbitrary shell commands without sanitization guidance.

• Add output schemas to all tools. Document return types, field names, and structure. Example: read_file returns {type: 'object', properties: {content: {type: 'string'}, encoding: {type: 'string'}}}.
• Implement dry-run mode for destructive operations (delete_file, delete_directory). Add dryRun boolean parameter defaulting to true, with clear messaging about what would be deleted.
• Add tool annotations: mark read-only tools with readOnlyHint: true, destructive tools with destructiveHint: true, idempotent tools with idempotentHint: true.
• Add pagination to list/search tools: include limit (default 20, max 100), offset/cursor parameters, and return total_count or next_cursor in response.
• Document error handling for each tool. Include recovery guidance: 'If file not found, use search_files() to locate it' or 'If command times out, increase timeout parameter or break into smaller steps'.
