Publish with Pagecast

Pagecast turns a local HTML or Markdown file (a report, plan, doc, or dashboard) into a shareable public URL in the user's Pagecast Home. Execute an explicit Pagecast request immediately; offer once when publishing would be useful but the user did not request it.

Consent and intent

• “Publish this as a Pagecast”, “Pagecast this”, or equivalent is sufficient

consent. Run the publish command immediately and return the URL; do not ask again.

• A proactive suggestion still asks once before publishing.
• If the user asks only for the command, provide the command and do not run it.

Claude Code Artifacts are also a valid publishing path. Do not disable or block Artifacts. When the user explicitly asks for a Claude Artifact, claude.ai artifact, or org-private artifact, use the Artifact flow. When the user explicitly asks for Pagecast or a Cloudflare Pages link, use Pagecast. When the user only says "publish", "share", "make a link", or similar, ask them which publishing path they want before doing anything.

When to offer

Default to offering. Whenever you produce an .html/.htm or .md/.markdown file that a person could reasonably share, proactively offer to publish it — once, right after you finish making it. Do not wait to be asked, and do not stay silent because you are unsure whether it is "worth it." If it could be shared, offer.

This includes:

• A report you generated — test/coverage/Lighthouse/Playwright output, a data

dashboard, an analysis, a "here's what I built/found" summary.

• A written plan, proposal, design doc, spec, release notes, or doc.
• A static web project that was just built, with a generated entry file such as

dist/index.html, build/index.html, out/index.html, or public/index.html.

• Any time the user says "share", "publish", "make a link for", or "send" a doc.
• A PostToolUse hint fired saying an HTML/Markdown file was created — treat that

as a cue to offer.

If the user says only "publish this" or "make this shareable" for a local report/doc/dashboard, ask them to choose between Claude Code Artifacts and Pagecast. The built-in Claude Code Artifact publisher is useful for claude.ai private/org pages. Pagecast is useful for external Cloudflare Pages URLs that can be renamed, re-synced, revoked, password-protected, or expired.

The only files to skip (don't offer): scratch/draft notes the user is clearly keeping private, source code, config files, secrets, and repo-meta files (README, CHANGELOG, CONTRIBUTING, LICENSE, AGENTS.md, CLAUDE.md, TODO/tasks), or anything under node_modules/dist build internals. When it is borderline, offer — the user can just say no.

Ask at most once per file. If the user declines or ignores the offer, drop it and don't re-ask for that file. Never nag across multiple turns.

The question to ask

When the user has not specified a publishing path, ask:

"How do you want to publish this? 1. Claude Code Artifact — private/org claude.ai page that can update in place. 2. Pagecast — Cloudflare Pages link you can share outside Claude, rename, re-sync, revoke, password-protect, or expire. 3. Don't publish."

Accept the number or the name. Only proceed after an explicit choice. An explicit request for Pagecast already selects Pagecast and provides publishing consent. If they choose Pagecast, run the Pagecast CLI below. If they choose Claude Code Artifact, use the Claude Artifact publishing flow and do not run Pagecast. Publishing may make content reachable outside the current chat, especially with Pagecast — never publish without confirmation.

How to publish

Run the headless CLI with the absolute path and --json:

npx pagecast publish "/absolute/path/to/file.md" --json

(HTML and Markdown both work — Markdown is rendered to a clean page. If pagecast is installed globally/in the project, pagecast publish "<path>" --json is the same.)

New links are unlisted capability URLs: a memorable prefix plus 128 bits of opaque entropy. Anyone with the URL can view it; unlisted does not mean private. The user can rename a link, add password protection, or make a short, shareable "drop" link from the npx pagecast app. Existing word-only links remain valid.

Managed links live in one user-level Home at ~/.pagecast/home/, under /p/<slug>/. The same item in the same agent context updates the existing URL; a new item or context creates a new URL. Pagecast stores only a local hash of the agent context identifier.

Publish options

Add any of these to a publish command:

• --expires <7d|12h|never> — edge-enforced link expiry (default 30d). The page

returns 410 once expired; --expires never keeps it live until revoked. The result JSON reports expiresAt (or none when never).

• --label "<name>" — set the page's display name in the Pagecast app.
• --context-id "<id>" — explicitly select the local agent context.
• --new-link — force a fresh URL.
• --update "<url|slug|token>" — update a known publication.
• --non-interactive — never open browser authentication; return a structured

authentication-required result instead.

npx pagecast publish "/absolute/path/to/report.html" --expires 7d --label "Launch report" --json

Password handling

Never ask the user to provide a page password in chat and never place a secret in an agent-generated command or tool argument. Publish the page first, then tell the user to open the local npx pagecast app and set password protection there. This keeps the credential out of the model and tool transcript.

Publishing a plan (e.g. after plan mode): the plan lives in your context, not a file yet. If the user wants it shared, first write the plan markdown to a file (e.g. ./plan.md), then publish that path. Don't overwrite an existing file the user cares about — pick a clear new name.

Live goal / progress page

When you're working toward a `/goal` (you'll see the goal condition in your context) and the work will span many turns / a long autonomous run, the user often can't see what's happening. Proactively offer once:

"Want me to publish a live progress page for this goal? You'll get a public link you can open anytime to see status and what's done."

On an explicit yes:

1. Write a pagecast-goal.md in the working dir with the goal, status, a

done/next checklist, and a one-line "latest", e.g.:

   # <short goal title>

   **Goal:** <the goal condition, in your own words>
   **Status:** In progress · updated <time>
   **Progress:** 3 / 8 steps

   ## Done
   - [x] <step>

   ## Next
   - [ ] <step>

   ## Latest
   <one line: what you just did / any blocker>

1. Run npx pagecast goal publish "<abs path>/pagecast-goal.md" --json and give

the user the returned url.

1. After each meaningful step, rewrite pagecast-goal.md and re-run the

same npx pagecast goal publish … --json — it guarantees the dedicated goal URL and keeps goal lifecycle separate from normal context upserts.

1. When the goal is met, do a final update; optionally npx pagecast goal stop.

There is one goal page per workspace. If a command reports recreated: true, the old link was gone and the URL changed — tell the user the new URL.

For static web projects that should get a new shareable /p/<slug>/ link, build first and publish the generated entry file:

npm run build
npx pagecast publish "/absolute/path/to/dist/index.html" --json

If the user asks to deploy or update an entire static site/project, deploy the built folder directly to a named Cloudflare Pages project:

npx pagecast publish site "/absolute/path/to/dist" --project "project-name" --branch main --json

--branch is optional and defaults to main, so this also works:

npx pagecast pages deploy "/absolute/path/to/dist" --project "project-name" --json

Use this instead of raw Wrangler commands like npx wrangler pages deploy. Direct site deploys replace the target Pages project contents, so do not guess the --project; use the user's named project or ask for it. Direct deploys do not change Pagecast's managed /p/... target, so use a separate project unless replacing that managed site is intentional.

Parse the JSON on stdout:

• Success → { "ok": true, "action": "created" | "updated", "publicationToken": "...", "contextMatched": true | false, "url": "https://<home>.pages.dev/p/<slug>/", ... }
• Give the user the url, say whether Pagecast created or updated it, offer to drop it into a PR/Slack message, and

mention they can rename the URL, re-sync, or revoke it from npx pagecast.

• Not signed in → { "ok": false, "statusCode": 401, ... }
• Interactive publishing normally starts Wrangler's browser authorization and

resumes automatically. This result is expected only for CI, --non-interactive, rejection, or timeout; relay it without sending the user to Settings.

• Multiple accounts → { "ok": false, "statusCode": 409, ... }
• Open npx pagecast, choose the Home account in the main onboarding canvas,

then retry. Settings remains available for later account switching.

• Any other error → relay error concisely and offer to retry.

Cloudflare Pages commands

Use these lower-level commands when the user explicitly asks about Cloudflare setup, status, project listing, or direct Pages deployment:

npx pagecast pages setup --project "project-name" --json
npx pagecast pages status --json
npx pagecast pages projects list --json
npx pagecast pages deploy "/absolute/path/to/dist" --project "project-name" --branch main --json

If the user does not specify a branch, omit --branch; Pagecast deploys to main.

Notes

• Always pass an absolute path (resolve relative paths against the cwd first).
• Publish from a dedicated artifact folder or finished dist/build/out export.

Pagecast rejects development workspaces and limits new source copies to 512 MiB / 10,000 files. For a standalone report saved in a repository root, stage only the report and its required assets in a separate folder; never copy the whole workspace to work around a source-validation error.

• The first interactive publish starts Wrangler login, creates the Home, and

resumes automatically.

• Use npx pagecast publish site or npx pagecast pages deploy for direct

static-folder deploys to a named Pages project.

• Use npx pagecast for source-folder build settings, URL renaming, re-sync,

and revoke controls.

• Re-running publish for the same item and agent context updates the same URL.

Use --new-link only when the user asks for another URL.
