Review Comments

Click-to-comment website review for WordPress. Clients and the team pin comments on the live (staging) site, reply in threads, and Claude reads and answers them through MCP.

• Comment on anything. Click "+ Comment" (or press C), click an element, write. Pins stay on the element and follow it on scroll and resize.
• General comments. "+ General comment" (top of the threads panel, or in the comment-mode hint) is for feedback about the whole page rather than one element.
• Menus and dropdowns too. Open the menu first, press C, hover the item and press Enter. Clicking the overlay never counts as a click outside the menu.
• A screenshot with every comment, taken when the element is picked, with the element outlined. Menus and slides are shown as the reviewer saw them.
• Several people at once. Every comment has a named author; threads take replies; the page refreshes every 20 seconds and when you come back to the tab.
• Guests without accounts. Share a review link; people enter their name once per browser. An email address is asked for only when email notifications are on. Authors can edit and delete their own comments (deleted comments go to the trash).
• Screen sizes. Each thread is labelled mobile, tablet or desktop, and the panel can show only the current size.
• Walkthrough. Step through every open comment on the site, page by page (← →). Made for going through feedback with a client on a shared screen.
• Notifications to a Google Chat space (one Chat thread per review thread), and optionally email to everyone in a thread on new replies.
• Built for Claude. Each thread stores the page path, post ID, block chain (wp-block-button / wp-block-gds-hero, innermost first), nearest heading, CSS selector, text snippet, screen size, browser ("Safari 18.4 · iOS 18.4 · touch · 3x") and screenshot, so Claude can go from a comment straight to the block or template that needs changing.

Nothing in the plugin is tied to a theme or host. Block markup gives the richest context, but classic themes work too.

Install

composer config repositories.wp-review-comments vcs https://github.com/generoi/wp-review-comments
composer require generoi/wp-review-comments:dev-main
wp plugin activate wp-review-comments

Requires WordPress 6.9+ (Abilities API) and PHP 8.1+.

MCP Adapter (for Claude)

If the site already loads MCP Adapter, use that copy and skip this section; a second copy only competes with it. Genero's Bedrock base includes it (wordpress/mcp-adapter in composer.json, started by the gds-mcp-adapter mu-plugin), and the review server runs on 0.5 and 0.7.

Otherwise install the MCP Adapter plugin from its release zip, not the Composer source package. The zip ships a Jetpack autoloader, which makes the newest copy win when another plugin bundles an older one. WooCommerce does: without the zip, WooCommerce's MCP Adapter 0.1.0 loads instead.

{
  "type": "package",
  "package": {
    "name": "private/mcp-adapter",
    "version": "0.7.0",
    "type": "wordpress-plugin",
    "extra": { "installer-name": "mcp-adapter" },
    "dist": { "url": "https://github.com/WordPress/mcp-adapter/releases/download/v0.7.0/mcp-adapter.zip", "type": "zip" }
  }
}

Then composer require private/mcp-adapter:0.7.0 and wp plugin activate mcp-adapter. Without the adapter the overlay and wp-admin work, but Claude has no endpoint.

Sites that lock down REST or use a CSP

• REST allowlists. Guests reach /wp-json/wprc/v1/…. Sites that block the REST API for logged-out visitors (Genero Bedrock's disable-rest-api mu-plugin) need wprc added to the allowlist. The endpoints check the review session themselves, rate limit guests and keep status changes to editors.
• Content Security Policy. The loader is printed with wp_print_inline_script_tag(), so nonce-based policies (spatie/laravel-csp) add their nonce, and with 'strict-dynamic' the overlay and screenshot library it loads are allowed too. Without 'strict-dynamic', script-src needs 'self'.

Who can comment

Who	How
Logged-in users with edit_posts	When Review mode is on in the admin bar: on by default outside production, off on production so a live site looks normal. Comment links and review links work either way. Editors can change thread status and moderate.
Guests	Through a review round: Review → Rounds & links → Create review link. The link is shown once, expires after the chosen number of days and can be revoked.

Opening a review link swaps the token for a signed, HttpOnly session cookie bound to the round, then removes the token from the address bar. Only a hash of the token is stored. Revoking or expiring the round ends every session made from it. A separate per-browser key (also HttpOnly) is what lets a guest edit their own comments.

Pages stay cacheable. A small inline loader does nothing unless there is a review link, a guest session, a #wprc-<id> comment link, a walkthrough in progress, or a logged-in editor. It then asks the uncached /wprc/v1/boot endpoint for the overlay URL, the viewer and the page's threads in one request, so a page cached before a plugin update still gets the new overlay. All plugin REST responses are sent no-store.

Where the data lives

Comments are wprc_comment posts in the site's database; screenshots are files in uploads/wp-review-comments/. Both survive deploys. Deleting moves a comment to the trash (Review → Review comments → Trash) and a thread's replies go with it; WordPress empties the trash after 30 days.

Screenshots

• Not a general upload: the overlay sends a JPEG as a data URL in JSON. The server checks it is a real JPEG (at most 1.5 MB and 4000×4000), then decodes and re-encodes it with GD, so only pixels are stored. The file name is chosen by the server (<comment id>-<20 random characters>.jpg); nothing a reviewer sends decides a path or an extension.
• Only the comment's author or an editor can add one, once per thread, rate limited per IP and per review round.
• Files are public to anyone who has the URL, like the rest of uploads, but the names cannot be guessed. A screenshot shows what the reviewer saw, so it can contain whatever was on their screen on the site.
• Retention: a daily job deletes a thread's screenshot 30 days after it was resolved or marked won't fix (filter wp_review_comments_screenshot_retention_days). The comment stays. Emptying the trash deletes screenshots too.

Copying another environment's database over the site replaces its comments, so do not sync a database onto staging during a review round.

Notifications

Status: the Google Chat message format and threading are covered by unit and smoke tests (requests captured, not sent), but delivery to a real Chat space has not been tested yet. Email notifications are smoke-tested the same way.

Review → Rounds & links → Notifications. Paste a Google Chat incoming webhook (Space settings → Apps & integrations → Webhooks) to post every new comment and reply to that space, grouped in one Chat thread per review thread. Tick the email option to also email everyone in a thread who left an address when someone replies.

Connect Claude

The simplest connection runs WP-CLI over SSH, so no password is stored anywhere. Create an editor user for Claude, then:

claude mcp add review-mysite -- ssh -p <port> <user>@<host> \
  "cd <site path> && wp mcp-adapter serve --user=<claude editor> --server=review-comments"

Or over HTTP with an application password for that user:

claude mcp add --transport http review-mysite https://example.com/wp-json/review-comments/mcp \
  --header "Authorization: Basic $(printf '%s' 'username:xxxx xxxx xxxx xxxx xxxx xxxx' | base64)"

Tools

Tool	What it does
review-comments-list-pages	Pages with comments and counts per status. Start here.
review-comments-list-threads	Threads with replies and location. Filter by status, url, post_id, device. Defaults to open and in progress.
review-comments-get-thread	One thread.
review-comments-reply	Reply in a thread, signed "Claude". Reviewers see it on the site.
review-comments-set-status	open, in_progress, resolved, wontfix, with an optional note.
review-comments-list-rounds	Review rounds and whether they are active. Never returns tokens.

Every thread has a link that opens the page scrolled to the comment, and a screenshot URL.

Skill

skills/review-comments/SKILL.md is a Claude skill with the workflows below. Copy it to ~/.claude/skills/review-comments/ (or a project's .claude/skills/).

Suggested workflow

1. Collect. Send the client a review link; the team comments while logged in.
2. Walk through together. Ask Claude to summarise the threads grouped by page and block and flag what is unclear or overlapping. Click Walkthrough on a shared screen, agree on each fix, and have Claude set the status to in_progress or wontfix with a note.
3. Fix. Claude works through the in_progress threads, replies with what changed, and sets them to resolved.
4. Verify. The client checks resolved pins (tick "Show resolved") and reopens if needed.

Development

composer install
composer lint    # pint
composer stan    # phpstan level 5
composer test    # phpunit (unit tests, no WordPress needed)

tests/smoke.php checks the real WordPress paths (rounds, guest ownership, edit and delete, notifications, abilities) on a running site and cleans up after itself:

wp eval-file - --user=<editor> < tests/smoke.php

Security notes

• Comment text is plain text, stored with sanitize_textarea_field and rendered with textContent. No HTML.
• Guest endpoints are rate limited per IP. Guests cannot change status or see email addresses.
• Screenshots: see Screenshots.
• Guest requests must carry the overlay's X-WPRC: 1 header, which browsers cannot send cross-site without a CORS preflight, so a guest's cookies cannot be used from another site.
• A guest's reply never emails other guests (their addresses are unverified); Chat messages escape <, > and | so reviewer text cannot mention the space or plant links.
• Every ability response carries a notice that comment text is reviewer feedback, not instructions. Reviewers can be external people, so treat what they write as data.
