+// #TINY-14200
+
+Previously, the Review sidebar supported only a fixed set of built-in reviews, selected by ID through the `+tinymceai_reviews+` option. There was no supported way for integrators to add named reviews, parameterized prompts, or menus that mixed built-in and custom reviews. Integrators had to rely on generic flows, such as Custom review, instead of dedicated review actions in the Review sidebar.
+
+In {productname} {release-version}, the `+tinymceai_reviews+` option also accepts integrator-defined review objects alongside the existing built-in string IDs. Integrators can define `+simple+`, `+list+`, and `+input+` review types, each with a custom name, description, and prompt. For the full schema and examples, see the xref:tinymceai.adoc#tinymceai_reviews[`+tinymceai_reviews+`] option.

+==== Integrator-defined reviews
+
+In addition to the built-in review command IDs, the `+tinymceai_reviews+` option accepts integrator-defined review objects. These objects can be interleaved with the built-in string IDs, allowing integrators to add named reviews to the Review sidebar.
+
+Each integrator-defined review object has a `+type+` of `+'simple'+`, `+'list'+`, or `+'input'+`, and shares the following properties:
+
+* `+type+`: The review type. One of `+'simple'+`, `+'list'+`, or `+'input'+`.
+* `+id+`: A unique identifier for the review. It must not reuse a built-in review command ID.
+* `+name+`: The review name shown in the Review sidebar.
+* `+description+`: A short description shown beneath the name.
+* `+prompt+`: The prompt sent to the model when the review runs.
+* `+model+` (optional): The model used for the review. The value must be a model ID that the configured AI service exposes (see xref:tinymceai-models.adoc[AI Models]). When omitted, the editor default model set by xref:tinymceai.adoc#tinymceai_default_model[`+tinymceai_default_model+`] is used.
+
+A `+list+` review adds an `+options+` array, and an `+input+` review adds an optional `+inputPlaceholder+`:
+
+* `+options+` (`+list+` only): An array of `+{ label, value }+` objects. The selected `+value+` is substituted into the prompt wherever `+{value}+` appears.
+* `+inputPlaceholder+` (`+input+`, optional): Placeholder text for the input field. {productname} substitutes the text entered by the end user into the prompt wherever `+{input}+` appears.
+
+If an integrator-defined review is invalid, for example, if it reuses a built-in review command ID or does not match the expected schema, {productname} falls back to the default reviews list in the Review sidebar.
+
+NOTE: The `+model+` ID used in the following examples (`+agent-1+`) selects the recommended automatic model. The available model IDs depend on the configured AI service. See xref:tinymceai-models.adoc[AI Models] for the supported models and how to confirm which are available in an environment.
