Molnify App Builder Skill — Design skill for Claude Code

Molnify App Builder - Agent Skill

The official [Agent Skill](https://agentskills.io) for building **Molnify apps** - spreadsheet-driven web apps where Excel or Google Sheets formulas do the calculation and colored cells define the inputs, outputs, charts, and actions.

It covers the whole job: building an app from scratch, converting an existing spreadsheet into one, validating it, and styling it. Inside are a `SKILL.md` entry point, companion reference guides, worked examples, and Python tools for inspecting and validating `.xlsx` files.

It's plain text and Apache-2.0 licensed, so there's nothing to take on trust: every instruction the agent follows and every line the Python tools run is readable right here.

What you can build

Calculators and quoting tools, ROI and pricing models, dashboards, multi-step forms and wizards, inspection and field-report apps with PDF output, internal tools backed by a database. If you can model it in a spreadsheet, you can ship it as an app.

Use it with any AI

It's an open Agent Skill, so it works the same in Claude Code, OpenAI Codex, Cursor, Gemini CLI, GitHub Copilot, and the other skills-compatible agents. Add it once and build Molnify apps from whichever one you already use. Any other AI works too: just point it at `SKILL.md`.
