Eidos
Eidos lets you keep a relational spreadsheet in a single TypeScript file that both you and AI agents can read and write, turning flat CSV‑like data into linked tables you can query programmatically.
- •You need a lightweight, version‑controlled data store for a prototype without setting up a full database.
- •Your AI agent (e.g., ChatGPT or Claude) must pull structured data and push updates during a workflow.
- •You want to share a single file with teammates that can be edited in a spreadsheet UI and also imported directly into code.
You are an AI sales assistant. Pull the latest high‑value customers from the spreadsheet `myData.eidos` and draft a personalized outreach email for each. Use the JavaScript snippet:
```js
const db = load('myData.eidos');
const prospects = db.query(`SELECT name, email FROM customers JOIN orders ON customers.id = orders.customer_id WHERE amount > 5000`);
// generate email for each prospect
```Skip the builder — one click puts this in Claude, Cursor, Antigravity and more.
Installs with a command or two; your AI agent can do it for you.
mkdir -p ~/.claude/skills/eidos && curl -fsSL https://workflowstacks.com/api/skills/eidos/claude-skill -o ~/.claude/skills/eidos/SKILL.mdOpens the app with this repo with the prompt ready to go — no copy-paste needed.
Eidos is a very large TypeScript project (~272k lines across 1056 code files, plus 23 test files). Setup is light: installs like a normal app. Reading the code is optional. Last commit this month, AGPL-3.0 license, has a test suite.
