Autograph App Builder

Autograph App Builder is a portable Agent Plugin for turning product ideas into working applications. Codex is the first entrypoint, and the public MCP contract exposes exactly five tools: autograph_start, autograph_get, autograph_send, autograph_respond, and autograph_cancel.

Develop locally

Use mise run dev. Edit live code, let HMR or the affected process reload, and retry the behavior. Vercel Sandbox is the execution backend and project-scoped OIDC is the provider credential boundary. The checkout is writable and new or generated files are expected.

Do not rebuild packages, run broad suites, publish, or deploy after every edit. Caches are optional accelerators, and inspection is best-effort. The builder does not block on exact versions, source drift, package layout, topology, receipts, digests, quotas, or other speculative conditions. See the local-development lifecycle and execution boundaries.

Use mise run eval:design -- --help to score an existing preview on demand. Design-quality evals report Arrusted token evidence, responsive/browser findings, and an advisory AI design score without regenerating the app or adding a runtime gate. Use --additional-desktop-size WIDTHxHEIGHT to add one explicit desktop window observation; the default three desktop captures remain unchanged.

The only pre-operation controls are credential/cross-user isolation and approval before outward effects. Actual provider or repository command errors are handled when they occur.
