Jetpack AI Sidebar: Add internal Proofreader sidebar feature flag by iamchughmayank · Pull Request #49825 · Automattic/jetpack

iamchughmayank · 2026-06-22T15:15:32Z

Proposed changes

Adds a host-side feature flag for a Proofreader (spelling & grammar) suggestion in the Jetpack AI Sidebar, mirroring the existing Generate Feedback flag. Internal
testing environments only; not user-facing.
- is_proofread_content_enabled() — internal-only, like Generate Feedback.
- Adds proofreadContent to the Jetpack AI Sidebar feature map, surfaced to the client at agentsManagerData.jetpackAiSidebar.features (built in
  get_jetpack_ai_sidebar_preview_config()).
- Re-asserts the flag after the jetpack_ai_sidebar_preview_features filter so a generic filter can't enable the internal feature outside internal testing environments.
The sidebar provider/UI lives in the companion Calypso PR; the backend ability lives in the companion wpcom PR.

Testing instructions

End-to-end testing (sandbox + this Jetpack branch + the Calypso provider) is covered in the companion wpcom PR: 224522-ghe-Automattic/wpcom

- Mirror Generate Feedback: dev-mode-only gate, emitted as proofreadContent in jetpackAiSidebarPreview.features for the sidebar provider to render the chip - Re-assert the flag after the preview-features filter so it cannot enable the internal feature - Include it in the master sidebar preview gate - Add tests for the default flag value and the filter guard Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Pull request overview

Adds a new internal-testing-only UI feature flag for a “Proofreader” suggestion in the Jetpack AI Sidebar Preview feature set, aligning it with the existing in-development suggestion gating approach (e.g., Generate Feedback).

Changes:

Introduce is_proofread_content_enabled() and expose proofreadContent in the sidebar preview features payload.
Re-assert proofreadContent after the jetpack_ai_sidebar_preview_features filter to prevent non-internal environments from enabling it via the generic filter.
Extend existing PHPUnit coverage to include the new proofreadContent flag behavior.

File	Description
projects/plugins/jetpack/extensions/plugins/ai-assistant-plugin/ai-sidebar/class-jetpack-ai-sidebar.php	Adds the Proofreader feature flag and includes it in the preview feature payload with post-filter re-assertion.
projects/plugins/jetpack/tests/php/extensions/plugins/ai-sidebar/Jetpack_AI_Sidebar_Test.php	Updates tests to assert `proofreadContent` is gated off outside internal testing and cannot be enabled by the generic features filter.
projects/plugins/jetpack/changelog/update-proofreader-ability	Adds a Jetpack plugin changelog entry for the new internal Proofreader sidebar flag.

- Drop redundant `Jetpack AI:` prefix in favor of `AI Sidebar:` (matches sibling entries; the plugin name is already implied in its own changelog) - `dev/internal mode` -> `internal testing environments`, matching the actual `jetpack_is_internal_testing_environment()` gate Addresses the Copilot review note on the changelog entry.
