**What it does.** Opens an HTML file, Markdown file, or localhost page in a browser editor where the user edits text directly, resizes images, and leaves Google-Docs-style comments; the edits and comments come back to the agent as structured feedback. Use it after writing anything the user will read (specs, plans, reports, newsletter drafts, landing pages, slide decks) instead of asking them to describe changes in chat. Announced in [this post](https://x.com/petergyang/status/2085006701984698712) as the follow-up to [[skill-no-ai-slop]].

## Install

- Any agent that reads SKILL.md files: `npx skills add petergyang/human-review` (the [skills CLI](https://github.com/vercel-labs/skills) installs into the folder your agent uses), or copy the file into `~/.claude/skills/human-review/SKILL.md` (Claude Code), `~/.codex/skills/human-review/SKILL.md` (Codex), or `.cursor/skills/human-review/SKILL.md` (Cursor).
- Raw file: `curl -sL https://raw.githubusercontent.com/petergyang/human-review/HEAD/src/SKILL.md`

## SKILL.md (verbatim)

```yaml
name: human-review
description: Open an HTML file, Markdown file, or localhost page in the browser so the user can edit text directly and leave comments on specific parts, then send all edits and comments back to you. Use after writing or updating something the user will read — specs, plans, reports, newsletter drafts, landing pages, slide decks, and locally running web pages.
```

# human-review

The user reviews your HTML, Markdown, or localhost page in a real browser: they fix small things
by typing, select anything to comment on it, and send you the whole batch at once.

Markdown files open rendered. Their quotes and edits reference the rendered text,
and the file itself is never touched — apply every change to the Markdown source,
keeping its formatting syntax.

## The loop

1. Write or update the HTML or Markdown file, or start the local page being reviewed.
2. Open it for the user:

   ```sh
   npx -y human-review path/to/file.html
   ```

   For a page served by a local development server, open the real route instead
   of recreating it as a separate HTML file:

   ```sh
   npx -y human-review http://localhost:3000/wiki
   ```

3. Wait for feedback. This command blocks until the user hits Send in the
   browser, then prints their batch and exits:

   ```sh
   npx -y human-review poll path/to/file.html
   ```

   The command exits only when the user clicks Send or closes the review.
   There is nothing to re-run, no interval to poll on, and no `--timeout` to
   add. It survives the local server restarting, and feedback is saved even
   if the poll dies, so nothing is ever lost. How you wait depends on your
   harness:

   - **Claude Code:** run it with `run_in_background: true` and end your turn.
     Claude Code wakes you with the output the moment the command exits.
   - **Codex, Cursor, and everything else:** run it in the **foreground**,
     inside your active turn, and stay on it until it prints `feedback` or
     `closed`. Do not detach it or start it as a background session: nothing
     wakes you when a detached command finishes. While the review is active:
     - If the user sends a message, answer it as commentary and immediately
       resume the foreground poll in the same turn. Do not send a final
       response until the poll returns `feedback` or `closed` — a final
       response ends the turn and kills the wait.
     - If your shell tool caps command duration, pass `--timeout` a little
       under the cap and run bounded polls back to back in the same active
       turn until one returns `feedback` or `closed`.

     Know the limit: this is reliable only while your turn stays active. A
     turn that has already ended is not woken when the user hits Send; the
     user has to message you, and you then run `status` and `poll` to pick
     the batch up. There is no integration that resumes an ended task when
     the poll exits.

   If it prints `{"status":"closed"}`, the review is over: the user ended it,
   closed the tab, or never had one open (`reason` says which). Stop and do
   not start another poll. `unsent` counts feedback they left behind; if it is
   not zero, tell the user in one line that it is kept and they can restore or
   discard it next time. `{"status":"superseded"}` means a newer poll of
   yours owns the wait — stop this one silently. `{"status":"timeout"}` only
   appears after 12 hours; run `status` and start the wait again if the
   review is still open.

4. Apply what comes back, then start the next background poll. `--ack` clears
   the batch you just handled:

   ```sh
   npx -y human-review poll path/to/file.html --ack
   ```

Repeat 3–4 until the user says they are done.

Not sure whether feedback is already waiting — say, at the start of a new turn
with no poll running? This answers instantly without blocking:

```sh
npx -y human-review status path/to/file.html
```

It prints `{"status": "feedback-waiting"}` when a batch is ready for a poll,
plus counts of unsent comments and edits still in the browser.

## What you get

One batch covers every page the user visited, grouped by file or localhost URL.

```json
{
  "status": "feedback",
  "pages": [
    {
      "file": "/abs/path/to/page.html",
      "edits_saved": true,
      "comments": [
        { "id": "c_1", "kind": "selection", "quote": "the exact text they selected",
          "anchor": { "prefix": "...", "quote": "...", "suffix": "..." },
          "feedback": "what they want changed" }
      ],
      "edits": [
        { "label": "Problem body", "kind": "edited",
          "before": "the original wording",
          "after": "their exact new wording",
          "after_html": "their exact new wording with <strong>formatting</strong>" }
      ]
    }
  ],
  "overall_note": "feedback not tied to any one page"
}
```

## Rules

- **`edits` are changes the user already made.** `after` is their exact wording —
  carry it across verbatim and never revert it. If the HTML was generated from
  something else (MDX, Markdown, a template), apply `after` to the **source** too,
  or their fix disappears on the next build.
- **`edits_saved: true` means those edits are already in the file on disk.**
  Plain HTML files autosave as the user types, so your copy of the file is
  stale. Re-read the file before touching it and make targeted changes only;
  never regenerate it from what you wrote earlier, or their work disappears.
  `edits_saved: false` (Markdown, localhost pages, self-rendering HTML) means the
  edits exist only in this batch — apply them to the source yourself.
- An edit with `kind: "deleted"` means the user removed that whole block:
  delete it from the source too, without asking why.
- An edit marked `truncated: true` had its text cut at 200k characters; read
  the block from the page itself rather than from `after_html`.
- When `before_html`/`after_html` are present, the user changed formatting, not
  just words — bold, italic, underline, links. Use the HTML version to carry the
  formatting into the source, translated to its syntax (e.g. `<strong>` → `**`
  in Markdown/MDX).
- A page with `kind: "url"` was edited directly in the review UI. Its `file`
  and `url` fields name the localhost route, not a writable file. Find the
  matching project source (such as MDX, TSX, or a template), apply every edit
  and deletion there, then acknowledge so the route reloads. Never write the
  rendered HTTP response back into the app.
- When an edit's `after_html` contains `<img src="assets/...">`, the user pasted
  an image: the file already exists in an `assets/` folder next to the reviewed
  file. Keep that relative path — in Markdown, reference it as
  `![](assets/...)`. Never regenerate or inline the image.
- On a localhost page, a pasted image arrives under `staged_assets`. Copy its
  local `path` into the app's appropriate asset folder, replace the temporary
  preview URL in `after_html`, and preserve the image at the user's insertion
  point. Never leave the temporary preview URL in source.
- An edit with `kind: "moved"` means the user relocated that whole block.
  Reposition it in the source without rewriting its content: it now sits right
  after the block whose text starts with `moved_after`, and right before the
  block whose text starts with `moved_before` (both are clipped to 90
  characters and may end in `…`). An empty `moved_after` means it is now the
  first block in its container.
- Find each comment by its `quote`. It is the **rendered** text the user
  selected, so in Markdown or templated HTML it may span formatting syntax or
  tags; `anchor.prefix` and `anchor.suffix` give the surrounding text to
  disambiguate.
- `kind: "element"` points at a whole block, so `quote` is its label, not body text.
- Copy any `staged_assets` files before you ack: `--ack` deletes them.
- A batch with only an `overall_note` has an empty `pages` array.
- Fix every page in `pages`, not just the first.
- **Do not write a reply.** There is no chat. The user sees your work when the page
  reloads, which happens on its own the moment you save the file.

## Better edit labels (optional)

Name the sections you author and the user's edit list uses your names instead of
guessing from the DOM:

```html
<p data-block="Problem body">…</p>
<div data-container="Metrics callout">…</div>
```

`data-block` names a region for the edit list. `data-container` also makes the block
clickable as a comment target.
