14 tools with basic schemas and descriptions, but significant gaps in parameter documentation and output schema clarity. Most tools have verb-noun naming (read_file, write_file, execute_shell) which is good. However, descriptions are often terse (10-50 chars), parameter descriptions are minimal or missing, and output schemas are not documented. No tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite clear risk levels. Error handling guidance is absent. Tools like execute_shell and call_mcp_tool are high-risk but lack confirmation/dry-run patterns. Composition is reasonable (single responsibility per tool), but chaining support is weak, no clear ID/reference propagation documented.

• Add output schemas to all tools. Document return types, field names, and structure. Example: list_mcp_servers should return {servers: [{name: string, description: string, tools: string[]}], total: number}.
• Add tool annotations (readOnlyHint, destructiveHint, idempotentHint) to all tools. Mark write_file, edit_file, execute_shell, execute_python, execute_r, call_mcp_tool as destructive. Mark read_file, list_directory, grep as readOnly.
• Expand parameter descriptions with format, constraints, and examples. E.g., grep.pattern: 'Regex pattern to search for (e.g., ^error.*failed$). Case-sensitive by default unless case_sensitive=false.'
• Add error recovery guidance to high-risk tools. E.g., execute_shell: 'If timeout occurs, reduce command complexity or increase timeout_seconds. If exit code is non-zero, check stderr output and retry with corrected command.'
• Implement confirmation/dry-run for irreversible operations. Add optional dry_run=true parameter to write_file, edit_file, execute_shell, execute_python, execute_r. Return what would happen without executing.
