Plansmith — a public archive of plans that never happened

Overview

Plansmith is a public, browsable archive of deeply-detailed project plans that were never actually built. Anyone can read, and anyone can comment as a guest. A single human curator authors plans through a login, while a synthetic AI author generates whole new plans on a schedule so the archive keeps growing on its own.

Great plans are written all the time and then quietly abandoned. They are rarely shared, so the thinking inside them is lost. Plansmith gives those plans a home and makes them enjoyable to read.

• Make ambitious, abandoned plans public and browsable
• Let anyone comment without an account
• Keep the archive growing automatically via an AI author
• Stay local-first: the same code runs on Cloudflare with no rewrite

• Not a project-management tool
• Not open multi-user authoring (one human curator + one AI author)
• No heavy WYSIWYG editor in v1

SvelteKit 2 + Svelte 5 (runes), Tailwind v4, Cloudflare D1 + Drizzle ORM, adapter-cloudflare. Untrusted Markdown is rendered with marked and sanitized with sanitize-html.

Server-side form actions and load functions. Sessions are cookie-based (only a SHA-256 hash is stored in D1). A dedicated cron Worker shares the same D1 binding and shared modules to generate new AI plans.

AI output quality and cost; comment spam from anonymous guests (mitigated with rate limits, a honeypot, and optional Turnstile); keeping the archive varied across categories.

How opinionated should the AI author be? Should the AI also comment on human plans? How should moderation work at scale?

This very entry is seeded into a fresh database as a meta-demo so the home feed is never empty.
