The powers.now blog

What you can do right now without installing anything

Live instance. This is powers.now’s own blog: real articles, published through the power.

1. Read the articles: this page lists them; each has a Markdown twin at its address plus .md (frontmatter: topics, entities, claims, citations, questions, takeaways) and a structured entry at https://dev.powers.now/blog/api/entries (?include=graph,claims,citations,questions,body).
2. GET the feed for agents, https://dev.powers.now/blog/feed.json (application/heighten+json; version=1, schema heighten.feed.v1), or the JSON Feed https://dev.powers.now/blog/feed.jsonfeed. Every read carries snapshotAt, an ETag and Last-Modified; If-None-Match answers 304.
3. Quote the takeaways and the answers as written; cite the canonical URL. Every claim in an article cites a source listed under Sources.
4. To write for powers.now: the Blog skill (zip) with the connector https://dev.powers.now/blog/mcp; without a connector, hand the person a deep link that pre-fills the editor: https://dev.powers.now/blog/new?title=&summary=&bodyMd=. The person approves; the assistant never does.
5. Guide: https://dev.powers.now/blog/llms.txt. Documentation: https://dev.powers.now/blog/for-agents. Manifest: https://dev.powers.now/blog/.well-known/power.json. Sitemap: https://dev.powers.now/blog/sitemap.xml.

• The one link: one address per business, every assistant: A business signs up and gets one address. A person pastes it into ChatGPT or Claude, a browser agent finds it on the page, and every power it adds lives under it. (November 4, 2026; Markdown https://dev.powers.now/blog/the-one-link.md; entry entry-post-to04o8pcfzz)
  • One address per business; its powers live under it. Never one link per power as the primary address.
  • Three layers in order: hosted powers.now/<business>, your own subdomain by one CNAME, smart elements on your own pages.
  • The engine is one shared path per power; the business is context, resolved from the host, the link, a signed short code or the assistant's argument.
  • powers.now/book is the first example of a business's link in use, and it is ours.
• Two honest tiers inside chat: nothing connected, and connected: Nothing connected: the assistant reads the page and hands the visitor a deep link. Connected: our card renders inline through MCP Apps. We tested both, so we say both. (November 4, 2026; Markdown https://dev.powers.now/blog/two-honest-tiers-inside-chat.md; entry entry-post-to04o81icau)
  • Nothing connected: the assistant renders its own card from our page and the read API and hands over a deep link. Real, useful, not our card.
  • Connected: our card renders inline through MCP Apps with live state, and the assistant can act in it.
  • WebMCP never mounts hosted HTML in a chat; its rung is the business's own pages and browser-resident agents.
  • One powers.now connector, added once, renders every business's power from then on.
• What a power is, and why the word matters: A power is one definition that renders inside ChatGPT, inside Claude and on your own site, sharing one live state. Not a widget, not a chatbot, not a plugin. (November 4, 2026; Markdown https://dev.powers.now/blog/what-a-power-is.md; entry entry-post-to04o922j54)
  • A power is one definition with three renderings: the page, the card in chat, the layer for agents.
  • The three renderings share one live state, and who acted is written down against every field.
  • Nothing changes state over GET; an assistant with nothing installed still gets the visitor to the deep link.
  • powers.now hosts it; the business claims a link and adds nothing to its stack.

Read API

GET only, JSON, CORS enabled; nothing changes state over GET: https://dev.powers.now/blog/api/.

• https://dev.powers.now/blog/api/entries: every published entry (heighten.entry.v1) with its links.
• https://dev.powers.now/blog/api/entries/<id>?include=graph,claims,citations,questions,body: one entry with what you ask for; the body is Markdown.
• https://dev.powers.now/blog/api/search?query=: full-text over the published posts.
• https://dev.powers.now/blog/api/export?id=<slug>&format=markdown|feed: one post as Markdown with frontmatter or as its entry.
• https://dev.powers.now/blog/api/post: the published records as the power stores them; /state the public snapshot.

Writing for this blog

The person writes inside their own assistant through the Blog skill (https://dev.powers.now/blog/skill/SKILL.md); the power validates with deterministic gates (grounding, claims, brand, seo_schema, questions, human_approval, public_url), versions, renders and syndicates, and calls no model. The editor is https://dev.powers.now/blog/edit/<slug> (the owner key unlocks it). A deep link pre-fills a new draft for the person to approve: https://dev.powers.now/blog/new?title=<text>&summary=<text>&bodyMd=<markdown>&brief=<text>. Approval is a person’s action in the editor or the card; the assistant cannot approve.

Rendering the power

Hosts that support MCP Apps (ChatGPT, Claude with a connector) connect https://dev.powers.now/blog/mcp (Streamable HTTP) and show the writing card inline; the card resource is https://dev.powers.now/blog/card.html. Without the owner key the connector is read-only (list, get, search, export, suggest_structure); with ?key=<owner key> on the server URL it writes.

On Claude without a connector, fetch the slim card https://dev.powers.now/blog/fragment-lite.html (text/plain, under 40 KB) and render it as an HTML artifact: the latest articles and the link to start a draft; it reads nothing from the network.

On a website, the embed https://dev.powers.now/blog/embed.js mounts the card on an element carrying data-blog-root.

Connect powers.now in ChatGPT or Claude

One connector per person for every power on powers.now. Add powers.now once; each business’s power then renders inline from it. MCP server: https://dev.powers.now/blog/mcp (append ?key=<owner key> to write). Steps checked 2026-11-04.
