Agents Manager: Add filter to skip enqueue in block editor contexts by aaronfc · Pull Request #47248 · Automattic/jetpack

Related to WOOAI-332

Add agents_manager_enqueue_in_block_editor filter so environments like CIAB can prevent agents-manager from loading in block editor asset requests where it is already running from the parent page.

Proposed changes:

Add a new agents_manager_enqueue_in_block_editor filter that allows disabling the gutenberg assets in the editor on demand.

Why is this needed?

CIAB doesn't load the block editor the traditional WordPress way (full page render with <script> tags). Instead, the SPA dynamically fetches block editor dependencies via a REST API call:

GET /wp/v2/editor/assets: PHP fires WordPress hooks (admin_enqueue_scripts, enqueue_block_editor_assets) in a synthetic context, captures everything that was wp_enqueue_script'd into JSON
Frontend loadAssets() takes that JSON and creates real <script> tags in the DOM

Agents-manager hooks into admin_enqueue_scripts so when the editor assets endpoint fires admin_enqueue_scripts it enqueues the gutenberg variant.

Later in the frontend this is processed, leading to a double chat UI interface: one per the original wp-admin variant and one for the new gutenberg variant due to this dynamic assets loading for the SPA.

In https://github.com/Automattic/big-sky-plugin/pull/5700/ and https://github.com/Automattic/big-sky-plugin/pull/5700/, I was going to add a filter, but I think I could make this approach here work if we adjust it like this.

Never mind! I'm going to switch it to agents_manager_enabled_in_block_editor for my filter because it serves a different purpose and then it'll complement this nicely.

is that an approval then? 🍏 ? @jom

aaronfc · 2026-02-24T19:08:54Z

@jom I have added a "Why" section to the PR description. This is because of how SPA loads the editor assets. Feel free to suggest an alternative route, but this approach makes sense to me.
