Hemrock Skill

Context, prompts, and sanity checks for editing Hemrock financial models. Covers the Standard Financial Model, Cap Table, Venture Fund Model (flagship + Quarterly Forecast), Fund Economics Tool, Venture Valuation, SaaS, Ecommerce, Unit Economics, and Runway. Point the AI at the template the user is editing; the skill supplies the sheet structure, task-specific prompts, and validation checks so edits match what the spreadsheet actually computes.

This repository is the canonical source for the Hemrock Agent Skill — a drop-in package of financial-modeling context, prompts, and sanity checks for Claude.

Canonical source: this repository is generated from the Hemrock content site. Don't edit files directly — edit the prompt library upstream and re-publish.
