Eidos File · SQLite
A single-file relational spreadsheet, for you and your .
Prompt for your agent
Help me complete a structured-data task in a .eidos file. Set up Eidos first if needed.
Start by asking what I want to accomplish, which .eidos file to use—or whether to create one—and where any source data is located. Do not install software or modify files yet.
After I answer:
1. Run `eidos --version`.
2. If the command is unavailable, detect the operating system, explain that the official installer downloads and verifies the standalone Eidos CLI, and ask for confirmation before running one of these commands:
macOS or Linux:
curl -fsSL https://download.eidos.space/cli/install.sh | sh
Windows PowerShell:
irm https://download.eidos.space/cli/install.ps1 | iex
If the current shell has not refreshed its PATH, locate the installed binary and continue using its absolute path.
3. Initialize the matching Eidos Skill in the directory containing the file:
eidos skills init --space "<directory>"
Use `--global` only if I ask to enable it for all projects. If an existing Skill differs, do not overwrite it with `--force`; explain the conflict and ask me what to do.
Then read the generated `.agents/skills/eidos/SKILL.md` and the references it requires for this task before continuing in the current session.
4. Use structured `eidos --json` operations to inspect the exact file context and current revision. Do not mutate yet.
5. Propose the smallest useful change, limited to the relevant tables, fields, relations, views, or rows, and wait for my confirmation.
6. After confirmation, use typed Eidos operations with the expected revision. Never write raw SQLite or Eidos internal tables directly.
7. Validate the result and summarize the file changed, previous and current revisions, exact changes, and validation result.
If you cannot run shell commands or access the installer, show me the exact next command and stop.Tables, relations, formulas, and views live in one standard SQLite file. Use the same file from the desktop, browser, CLI, or an agent.

Structured data you can keep reading.
Every .eidos file is SQLite. Standard SQLite tools can read its real tables today or years from now.
