Send your agent's work as a link, not a file.

A URL that survives every revision. Free, no signup, works with any agent.

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

Free · no signup · one human click to start

This is the response, trimmed. Read all of it.

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.

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.
