Roi Calculator Skill for Claude
Calculate comprehensive ROI for AI implementation projects. Takes current costs, manual process time, team size, and hourly rates. Generates detailed roi-analysis.md with executive summary, cost-benefit tables, sensitivity analysis, break-even timeline, and comparison scenarios. Use when evaluating AI investments, building business cases, or justifying automation spend.

Workflow
- Collect inputs. Gather every required cost, time, and labor input. If any required input is missing, ask for it in one organized message grouped by category. Do not guess. See
references/inputs.mdfor the full input list and defaults. - Apply defaults. For optional parameters the user omits, use the conservative defaults in
references/inputs.mdand note that defaults were applied. - Calculate metrics. Compute time savings, cost savings, net monthly savings, ramp-up adjustment, payback period, 12-month ROI, NPV, and productivity gain using the formulas in
references/methodology.md. - Run sensitivity and comparison scenarios. Produce conservative/base/optimistic cases and at least three comparison scenarios per
references/methodology.md. - Generate the report. Write
roi-analysis.mdto the current working directory followingreferences/output-template.md. Apply the formatting and calculation rules inreferences/rules-and-protocol.md. - Verify and summarize. Run the quality checklist in
references/rules-and-protocol.md, then report the top 3 findings and the saved file path.

Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.
