Explain this as an HTML page — visual, not a wall of text.

Publish it to htmlbin.dev. Start at htmlbin.dev/api/onboard.

$ npm i -g @htmlbin/cli && htmlbin login
$ htmlbin publish ./plan.html
→ htmlbin.dev/p/gDMy7Vb

# one-time
$ npx skills add utsengar/htmlbin-cli --skill htmlbin-publish
# then just ask your agent to publish anything

versions

### Revise without breaking the link.

Publish again and it becomes v2\. The link you already sent still works, and `?v=1` still shows the old one.

tags

### Find anything you published.

Tag a page when you publish it. Search by any combination of tags afterwards.

patterns

### Start from a real structure.

Shared shapes for the pages you make often — PR write-ups, plans, roundups. Use ours or write your own.

passcodes

### Keep some pages private.

Add a passcode and the page asks for it first. A share gate, not encryption — we say so plainly.
