Walkthrough

Version bumped to 0.2.1. The Chat action’s model prop now references a propDefinition from the Anthropic app. The constants file with static MESSAGE_MODELS was removed. The Anthropic app now defines a model prop with dynamic options fetched via a new listModels() method calling /models.

Changes

Cohort / File(s)	Summary of Changes
Dynamic model prop & API-backed options components/anthropic/anthropic.app.mjs	Added DEFAULT_MODEL and a public propDefinition model with async options() fetching models via new listModels(args={}) that requests /models; maps to label/value.
Chat action uses app propDefinition components/anthropic/actions/chat/chat.mjs	Version 0.2.0 → 0.2.1. Replaced explicit model prop (label/description/type/options/default) with propDefinition: [ anthropic, "model" ]. Removed dependency on internal constants.
Removal of static model constants components/anthropic/actions/common/constants.mjs	Deleted exported default containing MESSAGE_MODELS array; no options/defaults remain here.
Package version bump components/anthropic/package.json	Package version updated 0.2.0 → 0.2.1.

Poem

I thump my paws—new models bloom,
No dusty lists in constants’ room.
I sniff the /models breeze, so spry,
Options hop in, fetched on the fly.
Version bumped, I twitch with cheer—
Dynamic fields are crystal clear! 🐇✨

🧪 Early access (Sonnet 4.5): enabled

We are currently testing the Sonnet 4.5 model, which is expected to improve code review quality. However, this model may lead to increased noise levels in the review comments. Please disable the early access features if the noise level causes any inconvenience.

Note:

• Public repositories are always opted into early access features.
• You can enable or disable early access features from the CodeRabbit UI or by updating the CodeRabbit configuration file.

8-21: Add error handling for the dynamic options resolver.

The options() function calls listModels() without error handling. If the API call fails (network issues, authentication problems, rate limits), users will see an unhelpful error when trying to select a model.

Consider adding error handling and a fallback:

     async options() {
-      const response = await this.listModels();
-      return response.data.map((model) => ({
-        label: model.display_name,
-        value: model.id,
-      }));
+      try {
+        const response = await this.listModels();
+        return response.data.map((model) => ({
+          label: model.display_name,
+          value: model.id,
+        }));
+      } catch (error) {
+        console.error("Failed to fetch models:", error);
+        // Fallback to default model if API call fails
+        return [{
+          label: "Claude Sonnet 4.5 (default)",
+          value: DEFAULT_MODEL,
+        }];
+      }
     },

🔇 Additional comments (4)

components/anthropic/package.json (1)

3-3: LGTM! Version bump is appropriate.

The patch version increment from 0.2.0 to 0.2.1 is appropriate for adding dynamic model fetching functionality.

components/anthropic/anthropic.app.mjs (1)

42-47: LGTM! The listModels implementation is clean.

The method correctly uses the existing _makeRequest infrastructure and follows the established pattern. The GET method is correctly inferred by default.

components/anthropic/actions/chat/chat.mjs (2)

5-5: LGTM! Version bump is consistent.

The version bump to 0.2.1 aligns with the package version change.

---

11-16: LGTM! Clean refactoring to use propDefinition.

The migration from inline model configuration to propDefinition eliminates code duplication and centralizes model management. The model value is correctly consumed at line 83 in the createMessage call.
