high confidenceThis is an instruction-only skill that simply describes how to decompose RONA into component ratios; its requirements and instructions are consistent with that purpose.
评估建议
This skill is a benign, self-contained methodology template for RONA decomposition. Before using it: (1) confirm and sanitize the financial data you provide (balance sheet and income statement items) — do not send sensitive proprietary data unless you intend to; (2) verify the formulas and denominators used (e.g., definition of 'Net Assets', treatment of averages) match your accounting conventions; (3) pick appropriate industry benchmarks before benchmarking; and (4) treat outputs as analytic gu...详细分析 ▾
✓ 用途与能力
The name and description match the SKILL.md content: it provides a methodology for decomposing Return on Net Assets into margins and turnover components. The skill requests no binaries, environment variables, installs, or access beyond what is necessary for financial analysis.
ℹ 指令范围
The runtime instructions are limited to financial formulas, analysis steps, and output templates (define scope, gather balance sheet/income statement data, calculate ratios, benchmark, visualize). They do not instruct the agent to read system files, access external endpoints, or exfiltrate data. Note: the guide is a template and leaves data sourcing to the caller, so you should ensure any financial data supplied is appropriate and that the agent is given only the data you intend analyzed.
✓ 安装机制
No install spec and no code files — instruction-only skill. Nothing will be written to disk or downloaded by the skill itself.
✓ 凭证需求
The skill declares no required environment variables, credentials, or config paths. There are no disproportionate credential requests relative to the stated financial-analysis purpose.
✓ 持久化与权限
Flags show always:false and normal user-invocable/autonomous settings. The skill does not request persistent presence or elevated privileges and does not claim to modify other skills or agent configuration.

Metadata
- Name: rona-chart
- Description: Return on Net Assets component analysis
- Triggers: RONA, asset turnover, capital efficiency, asset utilization
Instructions
Analyze Return on Net Assets (RONA) by decomposing into component ratios to identify asset efficiency drivers.Framework
RONA Equation
RONA = (Net Income / Revenue) × (Revenue / Net Assets)
or
RONA = Net Profit Margin × Asset TurnoverWhere:
- Net Profit Margin = Net Income / Revenue
- Asset Turnover = Revenue / Net Assets
Extended RONA Tree
RONA (Net Profit / Total Assets)
│
├── Net Profit Margin
│ ├── Gross Margin (Gross Profit / Revenue)
│ ├── Operating Margin (Operating Profit / Revenue)
│ └── Net Profit Margin (Net Income / Revenue)
└── Asset Turnover
├── Revenue / Net Assets (overall)
├── Fixed Asset Turnover
├── Working Capital Turnover
└── Inventory Turnover
Key Ratios
| Ratio | Formula | Interpretation |
|---|---|---|
| Gross Margin | Gross Profit / Revenue | Production efficiency |
| Operating Margin | Operating Profit / Revenue | Core business efficiency |
| Net Profit Margin | Net Income / Revenue | Overall profitability |
| Asset Turnover | Revenue / Net Assets | Asset productivity |
| Fixed Asset Turnover | Revenue / Fixed Assets | Fixed asset utilization |
| Working Capital Turnover | Revenue / Working Capital | Working capital efficiency |
| Inventory Turnover | COGS / Inventory | Inventory efficiency |
Output Process
- Define scope - What assets to analyze?
- Gather data - Balance sheet, income statement
- Calculate ratios - Multi-year average preferred
- Decompose RONA - Analyze margin and turnover separately
- Identify drivers - What's impacting asset efficiency?
- Benchmark - Compare to industry standards
- Visualize - Waterfall chart or trend line

Tips
- Use multi-year averages to smooth volatility
- RONA is more stable than ROE - less affected by debt
- Compare by industry - asset intensity varies widely
- Decompose to identify levers - margin vs. turnover
