Eidos File · SQLite
A single-file relational spreadsheet, for you and your .
Prompt for your agent
Help me use Eidos File for my next structured-data task.
If either tool is missing, choose the command for this environment, explain what it will install, and wait for my confirmation before running it:
Eidos CLI · macOS and Linux:
curl -fsSL https://download.eidos.space/cli/install.sh | sh
Eidos CLI · Windows PowerShell:
irm https://download.eidos.space/cli/install.ps1 | iex
Eidos Skill · Node.js 18+:
npx skills add https://github.com/mayneyao/eidos/tree/cli-v0.36.6/skills/eidos --skill eidos -g
Before making changes:
1. Ask about my goal, data source, and .eidos file location.
2. Read the file context and current revision. Do not mutate yet.
3. Propose the smallest useful schema, field types, relations, and views, then wait for confirmation.
Use typed operations and revision checks from Eidos CLI or Eidos Skill. Do not bypass Eidos Runtime by writing internal tables directly. After making changes, run validation and briefly summarize what changed, the validation result, and the next step.
Start by asking what I want to accomplish; do not install tools or modify any files until I confirm.Tables, relations, formulas, and views live in one standard SQLite file. Use the same file from the desktop, browser, CLI, or an agent.
