## What capsule-creator does, in the publisher's words

SQLite Capsule explores a simple idea: one SQLite file can be an application, a document, a data store, an interactive visualisation, and an agent-readable software artefact at the same time.

This repository contains a format contract, generic hosts, authoring and verification tools, and one complete example. It is a reference implementation, not a production sandbox for arbitrary third-party code.

The distributable example is capsules/diagram-studio.capsule.sqlite. It contains the Diagram Studio application, structured diagram data, named data access declarations, validation checks, documentation, launch instructions, and a compatible fallback host.

- Versioned v0.2 and v0.3 SQLite format contracts with embedded START_HERE runbooks. V0.2 remains the default for the checked-in Diagram Studio example; v0.3 separates signed application releases from mutable capsule instances.
- A Python standard-library host that binds only to loopback and exposes named, parameterised endpoints instead of raw SQL.

## Skills

- create-capsule: Create, extend, build, verify, run, and black-box test exceptional product-independent SQLite Capsule applications from reviewable source. Use when Codex is asked to make a new capsule, turn an application or data brief into a `.capsule.sqlite`, scaffold a capsule project, design named database int…
