| name | htmldrop |
| description | Reach for this skill when an HTML artifact — report, deck, brief, mockup, dashboard, proposal, spec, or landing page, whether the user already has it or you just generated it — needs to reach other people or get tightened before it ships. Three situations: (1) they want a shareable link — public, or password-protected so only a client or specific people can open it; (2) they want reviewers to comment/annotate on it, then pull that feedback back to answer, fold, or synthesize into a revised version; (3) they want to co-edit it with you live and locally first — pointing at sections and commenting while you edit in real time, nothing deployed — to polish before sending. Cues: share, publish, get a link, password-protect, send to the client, collect or incorporate feedback, review it together, iterate in edit mode. Not for deploying apps/frameworks (Vercel, Next.js, npm), CSS/layout debugging, PDF annotation, A/B testing, or emailing screenshots. |
htmldrop — Share HTML as Hosted Links
Publish any HTML file and get a shareable URL instantly via the htmldrop CLI. Three modes:
- Simple share (Surge.sh hosting) — get a public or password-protected link to a static page.
- Collaborative feedback + converge — publish with an embedded annotation widget so reviewers can highlight text and comment with no account, then pull the feedback, add evidence-backed comments programmatically, and synthesize an improved version with AI.
- Edit mode (local, pre-publish) — serve the file on
127.0.0.1 and iterate on it live with the user: they annotate and comment on one surface; you edit the file (it hot-reloads), reply, or ask them a question. No hosting, nothing published. This is the loop to firm a doc up before sharing it — or between rounds of external feedback. See references/edit-mode.md.
Design applies to every mode: before generating or serving any HTML, match the design system of the project the artifact is about, so it looks like the real product rather than a generic page. See references/design-and-visuals.md — read it whenever you author or edit HTML here.
Prerequisites
- Node.js >= 18
npm install -g @yeefeiooi/htmldrop@latest (the binary is still htmldrop)
- For simple share: run
htmldrop init once (sets up Surge account + subdomain)
- For feedback/converge: run
htmldrop auth setup once (generates an author API key in ~/.htmldrop/config.json)
- For edit mode: nothing — it's fully local (no
init, no Surge, no auth key). Lowest-friction entry point.
Critical Rules
- Check prerequisites first — the relevant setup must be done before any push
- Never store credentials — Surge auth lives in
~/.netrc; the feedback author key lives in ~/.htmldrop/config.json
- For password-protected files — report both the URL and the password to the user
- Use absolute paths when calling
htmldrop push
Mode 1: Simple Share (Guided Flow)
This is the most common case — "just give me a link." Follow this sequence.
Step 1: Verify Environment
which htmldrop
test -f ~/.htmldrop/config.json && echo "initialized" || echo "not initialized"
If not set up, direct the user to run htmldrop init interactively. The first deploy triggers Surge's interactive email/password login. After that, the token is saved in ~/.netrc and future deploys are automatic.
Step 2: Ask Privacy Preference
Present two options:
- Public — Anyone with the link can view it
- Password-protected — Content is AES-256 encrypted; viewers need a password to unlock
Step 3: Handle Based on Choice
If public — ask one follow-up: "Block search engines and AI crawlers from indexing?"
- Yes →
htmldrop push --noindex /path/to/file.html
- No →
htmldrop push /path/to/file.html
If password-protected — ask for a password or offer to generate a memorable one (e.g., coral-sunset-42):
htmldrop push --password <pass> /path/to/file.html
Step 4: Report Results
Public:
Published: https://subdomain.surge.sh/filename.html
Password-protected:
Published with password protection!
URL: https://subdomain.surge.sh/filename.html
Password: coral-sunset-42
Share both with your recipients.
Skip the Flow When Intent is Clear
If the user explicitly states preference in their request, skip the question:
- "Share report.html publicly" → push directly
- "Share spec.html with password hello123" → push with provided password
- "Publish this privately" → go to password flow
Simple-Share Commands
| Command | Purpose |
|---|
htmldrop init | One-time setup (subdomain + Surge login) |
htmldrop push <file> | Publish a file (flags: --password, --noindex, --open) |
htmldrop list | Show all published files with URLs |
htmldrop delete <file> | Remove a file and redeploy |
htmldrop open <file> | Open published file in browser |
Mode 2: Collaborative Feedback & Converge
Use this when the user wants people to review and comment on an HTML doc, spec, or report — or when they want to pull, answer, or synthesize that feedback. Publishing with --feedback embeds an annotation widget in the page.
The Single-URL Model
htmldrop push <file> --feedback prints one shareable Feedback URL like:
https://htmldrop-feedback.htmldrop.workers.dev/doc/<uuid>
That single /doc/<uuid> link serves everyone:
- Reviewers open it, highlight any text (or drag a box over an area via the ▢ toggle) and leave comments — no account, no login. They comment anonymously (an optional name field is available).
- The author uses the same link to see the page with all comments rendered inline.
There is no separate "viewer link" vs "author link." Share the one URL and you are done.
The link is stable. Re-pushing the same file with --feedback reuses its docId, so the URL never changes and existing comments stay attached. This is why the agent loop below works: you can keep updating the document at the same link as feedback comes in. Use --new-doc only when you deliberately want a fresh, empty doc.
Prerequisites for this mode
htmldrop auth setup run once (creates the author API key). Add --force to regenerate it.
converge additionally needs an LLM API key (Anthropic, OpenAI, or Gemini) in the environment — ANTHROPIC_API_KEY, OPENAI_API_KEY, GEMINI_API_KEY, or LLM_API_KEY. The provider is auto-detected from the key; override with --provider/--model. No SDK install needed.
Feedback & Converge Commands
| Command | Purpose |
|---|
htmldrop auth setup [--force] | One-time: generate an author API key. Required before any feedback feature. |
htmldrop push <file> --feedback | Publish with the annotation widget; prints a stable Feedback URL. Re-push same file → same link, comments preserved. |
htmldrop push <file> --feedback --password <pw> | Feedback-enabled private doc — the widget appears after the viewer decrypts. Review link is the password-gated URL (reviewers need the password). |
htmldrop push <file> --feedback --new-doc | Force a fresh feedback doc/link (clean slate). |
htmldrop feedback pull <file> [--json] | Retrieve feedback for your own file (uses local manifest + author key). |
htmldrop feedback read <docId|url> [--json] | Read feedback for any doc by id or link — no ownership/manifest. Use this when reviewing a teammate's doc. |
htmldrop feedback list | List which published files have feedback enabled. |
htmldrop feedback add [file] --text "..." [--doc-id <id|url>] [--name "..."] [--on "<anchor>"] [--parent-id <id>] | Post a comment (the agent write path). --doc-id comments on a doc you didn't publish; --on anchors to text; --parent-id replies. |
htmldrop feedback clear <file> | Delete all feedback for a file (owner only). |
htmldrop fetch <url> [--password <pw>] [--out <f>] | Fetch + decrypt a published doc so the agent can read its content (use with a teammate's link + password). |
htmldrop converge <file> [--dry-run] | One-shot: pull all feedback → LLM → write <file>.converged.html, auto-resolving disagreements (owner only). --dry-run prints the prompt without calling the API. |
htmldrop studio [--port <n>] [--no-browser] | Open the local "Converge Studio" dashboard to review feedback + trigger AI insights. |
Roles: anyone with the link is a reviewer (read + comment, via feedback read / feedback add --doc-id / fetch — no key). The owner (author-key holder who published) additionally runs converge and feedback clear. So a teammate's Claude/Codex session can fully review a shared doc, but only the owner synthesizes/converges it.
The Agent Loop
When Claude generates a doc/spec/report and the user wants collaborative review, this is the workflow:
-
Generate & publish — write the HTML, then:
htmldrop push /path/to/doc.html --feedback
Share the printed Feedback URL with the user. Reviewers comment on it directly.
-
Pull feedback — when the user asks what reviewers said, or before synthesizing:
htmldrop feedback pull /path/to/doc.html
-
Inject researched answers (optional but powerful) — Claude can respond to a comment with its own evidence after researching. Anchor the reply to the exact text being discussed:
htmldrop feedback add /path/to/doc.html \
--text "Verified against the 2026 pricing docs: the tier cap is 500 req/s, not 200." \
--name "AI Research" \
--on "the rate limit is 200 req/s"
Use --parent-id <id> to reply directly under a specific reviewer comment instead of anchoring to text.
-
Converge — synthesize all comments into an improved document. Two paths:
- One-shot (automated):
htmldrop converge /path/to/doc.html pulls all feedback, calls an LLM, and writes /path/to/doc.html.converged.html. It auto-resolves disagreements itself. Review it, then promote it over doc.html once it looks right. Use --dry-run first to inspect the prompt without spending an API call.
- Interactive (human-in-the-loop): when you edit the doc directly instead, work in two tiers — fold in the clear wins (objective improvements with nothing to decide, e.g. a vague success metric → a concrete, measurable target) but leave judgment calls for the human (genuine disagreements / strategic forks, e.g. "ship iOS-first vs Android-first"): don't silently pick one — leave that part unchanged and lay out both sides with a recommendation so the human decides.
-
Close the loop — post resolutions back as replies. After you fold in a comment or the human decides an open item, reply on that reviewer's comment so the resolution lives on the document (reviewer refreshes the link → sees their comment was addressed → and why):
htmldrop feedback pull /path/to/doc.html --json
htmldrop feedback add /path/to/doc.html --parent-id <id> --name "<author>" --text "<how it was resolved>"
For a password-gated doc, add --password <pw> to the reply (gated feedback requires the token derived from the password).
-
Re-push to the same link — publish the improved version so reviewers see it update in place:
htmldrop push /path/to/doc.html --feedback
Same URL, comments intact. The loop can repeat as more feedback arrives.
For the detailed walkthrough — single-URL mechanics, anchoring rules, the two-tier converge (clear wins vs. judgment calls), closing the loop with reply resolutions, and troubleshooting — read references/feedback-workflow.md.
Mode 3: Edit Mode (Local, Real-Time Iteration)
Use this when the user wants to refine an HTML doc or page with you, live, before publishing — not to collect async feedback from others. It runs entirely on 127.0.0.1; nothing is hosted.
The core is a listen loop: you serve the file, the user annotates/comments in the browser, and you poll to receive their input, edit the file, and it hot-reloads. Minimal shape:
htmldrop edit start /abs/path/doc.html
htmldrop edit poll /abs/path/doc.html --json
htmldrop edit reply /abs/path/doc.html --text "what you changed"
Keep edit poll running like any long-poll — it stays silent until there's input, so re-run it after each reply. When the doc is ready, publish with htmldrop push --feedback (Mode 2) for external review. To iterate on feedback you already collected, htmldrop edit start <file> --with-feedback loads those reviewer comments into the session.
Read references/edit-mode.md before running an edit session — it has the full command reference, the poll payload shape (messages / comments / layout warnings), the listen-loop pattern, and how design/theme matching applies here.
Generate Then Share
When the user asks to create an HTML artifact AND share/review it:
- Generate the HTML file and write it to disk — matching the project's design system (
references/design-and-visuals.md)
- Verify it exists:
test -f /path/to/file.html
- Pick the mode:
- Just a link → follow the Simple Share guided flow
- Collaborative (async) review → use
--feedback and follow the Agent Loop
- Iterate live with the user first → Edit mode (
references/edit-mode.md), then publish when ready
Troubleshooting
| Issue | Fix |
|---|
htmldrop: command not found | npm install -g @yeefeiooi/htmldrop@latest |
| Not initialized (simple share) | Run htmldrop init interactively |
| Auth error on push | Run htmldrop init to re-authenticate |
| Feedback command rejected / no author key | Run htmldrop auth setup once |
converge fails | Ensure an LLM key is set (ANTHROPIC_API_KEY / OPENAI_API_KEY / GEMINI_API_KEY / LLM_API_KEY); pass --provider if the key prefix is unrecognized |
| Feedback link changed unexpectedly | You likely passed --new-doc; omit it to keep the stable link |
| File not found | Use absolute path |
| Change password | Re-push with new --password (overwrites) |
edit poll returns nothing | Correct — it blocks silently until the user acts. Leave it running; re-run after each reply |
| Edit session won't start / stale | htmldrop edit stop, then htmldrop edit start <file> again |
