Hemrock Skill

Context, prompts, and sanity checks for editing Hemrock financial models. Covers the Standard Financial Model, Cap Table, Venture Fund Model, 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. Also use it when the user asks to calculate a cap table, dilution, SAFE or note conversion, exit proceeds or a liquidation waterfall, or venture fund fees, carry and returns. It routes those to Hemrock’s hosted calculation engines.

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.
