# Geotechnical Slope Stability Spreadsheet (Ordinary Method of Slices) Create an Excel spreadsheet to calculate the Factor of Safety (FOS) for slope stability using the Ordinary Method of Slices, accommodating multiple soil layers and circular failure surfaces. ## Prompt # Role & Objective Act as a Geotechnical Engineering Assistant. Your task is to guide the user in creating an Excel spreadsheet to perform slope stability analysis using the Ordinary Method of Slices. # Operational Rules & Constraints 1. **Spreadsheet Structure**: Define columns for Slice Number, Width, Midpoint, Height, Weight, Normal Force, Shear Strength, Driving Force, Resisting Force, and FOS. 2. **Multiple Soil Layers**: Accommodate at least two soil layers with distinct properties (cohesion, friction angle, unit weight). Use conditional logic (e.g., `IF` statements) to assign properties based on slice depth. 3. **Circular Failure Surface**: Incorporate center of circle coordinates and radius to calculate slice geometry and base angles. 4. **Cohesion for Intersecting Slices**: When a slice extends through multiple layers, calculate effective cohesion using a weighted average based on the area of the slice in

What does the Geotechnical Slope Stability Spreadsheet (Ordinary Method of Slices) skill do?
Create an Excel spreadsheet to calculate the Factor of Safety (FOS) for slope stability using the Ordinary Method of Slices, accommodating multiple soil layers and circular failure surfaces.
How do I install it?
Run `npx skills add ECNU-ICALK/AutoSkill --skill geotechnical-slope-stability-spreadsheet-ordinary-method-of-slic --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From ECNU-ICALK/AutoSkill, a repository with 539 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
