Local drafts — a review loop for agent-authored HTML. Your coding agent writes a rich HTML/SVG draft to a file; marigold-draft open serves it in a comment shell in your browser; you highlight, comment, and edit in place; Send feedback to agent returns your review to the agent's blocked CLI call as JSON, and its next save live-reloads the tab with your comments re-anchored.

No database, no accounts, no network. One warm background daemon; comments persist in a sidecar file next to the draft.

npm i -g marigold-draft
marigold-draft agent-setup   # wires up Claude Code (skill) + Claude Desktop (MCP)

Or hand this prompt to your coding agent:

Install Marigold for me using npm i -g marigold-draft, then read https://marigold.page/draft/setup.md and set yourself up to use it.

Full docs: packages/local/README.md — the agent loop, in-place edits, .svg drafts, sharing, and graduating a draft to hosted Marigold when you want a link you can send to someone.

What's in this repo

Package	What it is
`packages/local`	`marigold-draft` (npm) — the CLI, daemon, review shell, and MCP server
`packages/core`	The shared anchoring engine: deterministic element instrumentation, composite comment anchors (`marigoldId → css → textQuote`), and the Marigold Way methodology packs. Bundled into the CLI at build time.

The anchoring engine is the same one hosted Marigold runs, so comments re-anchor identically across draft revisions locally and doc versions in the cloud, and a draft promoted to the cloud instruments byte-for-byte the same.

pnpm install
pnpm test        # vitest across both packages
pnpm build       # bundles packages/local/dist/cli.cjs

Relationship to hosted Marigold

Hosted Marigold ("Google Docs for AI-generated webpages" — share by email, comment on the rendered page, agents read feedback over MCP) is a separate, closed-source service. This repo is the open-source local tool, MIT-licensed, and is where its issues and pull requests live.

Development happens in a private monorepo that also contains the hosted service; the OSS subset is auto-synced here on every change, so this mirror is always current. PRs are welcome — they're reviewed here and ported onto the internal tree with your authorship preserved.
