🤖 Fix all issues with AI agents
In @docs/cli-reference.md:
- Around line 69-79: The Video Generation options table is missing the --image
flag used in the examples; add a new row in the "Video Generation (Veo 3.1)"
flags table documenting `--image` (type: string, default: none, description:
Path to an input image to base the generated video on, e.g., ./input.png),
ensuring it appears alongside the other flags (`--outputMode`, `--videoOutput`,
`--videoResolution`, `--videoLength`, `--videoAspectRatio`, `--videoAudio`) so
examples referencing --image are documented and unambiguous.

In @docs/configuration.md:
- Around line 197-213: The Video Generation (Veo 3.1) block is unclear and
mis-nested: make it a top-level peer section (match the heading level used by
other provider sections like "Evaluation & Analytics Controls" and "Conversation
Memory & Redis") and clarify credential options by labeling two explicit
alternatives—Option 1: Service account file (keep GOOGLE_APPLICATION_CREDENTIALS
and include GOOGLE_VERTEX_PROJECT / GOOGLE_VERTEX_LOCATION used by Vertex);
Option 2: Environment variables (use GOOGLE_CLOUD_PROJECT /
GOOGLE_CLOUD_LOCATION as an alternative mapping to the same project/location
configuration). Update the comments to state these are alternatives (not
required together) and explicitly note that GOOGLE_VERTEX_* are the
Vertex-specific vars while GOOGLE_CLOUD_* are equivalent environment variable
names, so users may use either approach.

In @docs/features/multimodal-chat.md:
- Around line 15-29: The example calls readFile and writeFile but omits their
imports, causing copy-paste failure; add the appropriate imports at the top
(e.g., import readFile and writeFile from fs/promises or the environment's file
API) so the calls to readFile("./product.jpg") and writeFile("output.mp4",
result.video.data) compile; ensure the example still shows neurolink.generate
usage and keeps provider/model/output options unchanged.

In @docs/reference/provider-feature-compatibility.md:
- Around line 36-46: The score totals are inconsistent because the new "Video
Gen" column is included for Vertex AI (showing 20/20) but not counted for other
providers (still 19/19); update the table so every provider uses the same
denominator—either add the Video Gen column value for all providers (mark as
❌/⚠️/✅ as appropriate) and adjust all totals to out of 20, or keep totals at 19
and annotate Video Gen as provider-specific in the legend; specifically edit the
"Video Gen" column entries and the bold totals (e.g., the row showing "Vertex AI
| ... | **20/20**" and rows showing "**19/19**") and add a clarifying note in
the legend/methodology referencing "Video Gen" and scoring rules.

In @docs/testing.md:
- Around line 345-380: The mock currently calls actual.generate(options) but
`actual` is the imported module from vi.importActual("@juspay/neurolink"), not a
NeuroLink instance, so calling actual.generate will fail; fix by either removing
the fallback and returning a default mock response for non-video modes inside
MockNeuroLink.generate, or if you need real behavior instantiate the real class
(e.g., new actual.NeuroLink(...)) and call its generate method instead; update
the mock returned by vi.mock to reference MockNeuroLink.generate and avoid
calling actual.generate directly.

In @docs/tutorials.md:
- Around line 89-93: The "Video Generation Options (Veo 3.1)" section in
docs/cli-guide.md is missing the --image flag; update that section to include
the --image CLI flag (same name used in examples and in
docs/features/video-generation.md) with a short description, mark it as required
for image-based video generation, and show its expected value (path to an image
file) so the section matches examples and other docs and improves
discoverability.
🧹 Nitpick comments (16)
docs/cli-reference.md (1)

278-309: Specify provider and model in the first example for clarity.

The first "Basic video generation" example (lines 283-287) doesn't specify --provider or --model, relying on defaults. However, video generation is a specialized feature that requires Vertex AI and Veo 3.1. New users might not realize this and could encounter errors if their default provider isn't Vertex AI.

📝 Recommended enhancement
 # Basic video generation
 npx @juspay/neurolink generate "Product showcase with smooth camera movement" \
   --image ./product.jpg \
+  --provider vertex \
+  --model veo-3.1 \
   --outputMode video \
   --videoOutput ./output.mp4

Alternatively, add a comment above the example:

# Basic video generation (requires Vertex AI with Veo 3.1)
npx @juspay/neurolink generate "Product showcase with smooth camera movement" \
  --image ./product.jpg \
  --outputMode video \
  --videoOutput ./output.mp4
docs/cli/commands.md (2)

61-69: Add context about video generation requirements.

Similar to the issue in cli-reference.md, this section doesn't clarify that:

  1. The --image flag (documented earlier in the file) is required for video generation
  2. Video generation requires Vertex AI provider and Veo 3.1 model
📝 Recommended addition
 **Video Generation (Veo 3.1):**
+
+> **Note:** Requires `--image` flag, `--provider vertex`, and `--model veo-3.1`. See [Video Generation Guide](../features/video-generation.md) for setup.
 
 - `--outputMode` – output mode: `text` (default) or `video`.
 - `--videoOutput`, `-vo` – path to save generated video file.

61-69: Consider consistency in default value notation.

Minor formatting inconsistency: Some flags show explicit defaults in the description (e.g., "default 720p", "default true"), while the "Default" column in the table format used elsewhere in the file typically contains this information.

For consistency with the rest of the document, consider using the table format used for the main generate command flags (lines 44-59). However, this is a stylistic choice and the current format is also acceptable.

docs/tutorials.md (2)

54-84: Document image format and size limitations.

The SDK example shows using an image input, but doesn't mention important limitations that are documented in the troubleshooting guide (line 68):

  • Supported formats: PNG, JPEG, or WebP only
  • Maximum file size: 20MB
  • Aspect ratio compatibility requirements

Consider adding a comment or note about these limitations to prevent common user errors.

📝 Suggested addition

Add a comment before the example:

 ### SDK Video Generation
 
 ```javascript
 import { NeuroLink } from "@juspay/neurolink";
 import { readFile, writeFile } from "fs/promises";
 
 const neurolink = new NeuroLink();
 
+// Note: Image must be PNG, JPEG, or WebP format, under 20MB
 // Generate video from image + text prompt
 const result = await neurolink.generate({

86-105: Add note about automatic provider selection for video generation.

The troubleshooting guide (line 69) mentions that "provider auto-switches to vertex when output.mode: "video"", but this important behavior isn't documented in the tutorial. Users might be confused why the --provider vertex flag is shown in the full example if it's automatic.

Consider adding a note explaining this behavior, or clarifying that the --provider flag is optional for video generation.

📝 Suggested addition
 ### CLI Video Generation
 
 ```bash
+# Note: Provider automatically switches to 'vertex' for video generation
 # Basic video generation
 npx @juspay/neurolink generate "Product showcase video" \
   --image ./product.jpg \
   --outputMode video \
   --videoOutput ./output.mp4
docs/cli-guide.md (1)

127-135: Add default value for --videoAspectRatio.

All other video generation options document their default values, but --videoAspectRatio (line 133) does not. Consider adding a default (likely 16:9 for landscape, which is more common) or explicitly state that this parameter is required.

Comparison with other options:

  • Line 131: --videoResolution has default 720p
  • Line 132: --videoLength has default 6
  • Line 134: --videoAudio has default true
  • Line 133: --videoAspectRatio - no default specified
📝 Suggested fix
-- `--videoAspectRatio <ratio>` - Aspect ratio: '9:16' (portrait) or '16:9' (landscape)
+- `--videoAspectRatio <ratio>` - Aspect ratio: '9:16' (portrait) or '16:9' (landscape, default)

Or if required:

-- `--videoAspectRatio <ratio>` - Aspect ratio: '9:16' (portrait) or '16:9' (landscape)
+- `--videoAspectRatio <ratio>` - Aspect ratio: '9:16' (portrait) or '16:9' (landscape) [required]
docs/use-cases.md (2)

91-91: Replace console.log with proper logging.

The PR checklist indicates that "logger used instead of console.log" is required. While this is example/documentation code, users often copy examples directly into production. Consider replacing this with a comment suggesting proper logging or use a logger library in the example.

📝 Suggested improvement
-  console.log(`Video generated: ${videoResult.video.metadata?.duration}s`);
+  // Use your application's logger in production
+  logger.info(`Video generated: ${videoResult.video.metadata?.duration}s`);

69-92: Add error handling to the example.

The video generation example lacks error handling, which could mislead users implementing this feature. Video generation can fail due to various reasons (quota limits, invalid input, timeouts, etc.), as documented in the error-handling.md file.

🛡️ Add error handling
+try {
   const videoResult = await neurolink.generate({
     input: {
       text: `Smooth camera movement showcasing ${product.name} 
       with elegant rotation revealing product details`,
       images: [await readFile(product.heroImagePath)],
     },
     provider: "vertex",
     model: "veo-3.1",
     output: {
       mode: "video",
       video: {
         resolution: "1080p",
         length: 8,
         aspectRatio: product.platform === "instagram" ? "9:16" : "16:9",
         audio: true,
       },
     },
     enableAnalytics: true,
+    timeout: 180, // 3 minutes for video generation
   });
 
   if (videoResult.video) {
     await writeFile(`${product.id}-showcase.mp4`, videoResult.video.data);
     logger.info(`Video generated: ${videoResult.video.metadata?.duration}s`);
   }
+} catch (error) {
+  if (error.code === 'VIDEO_POLL_TIMEOUT') {
+    logger.error('Video generation timed out. Try reducing video length.');
+  } else if (error.code === 'VIDEO_QUOTA_EXCEEDED') {
+    logger.error('Vertex AI quota exceeded. Check billing and quotas.');
+  } else {
+    logger.error('Video generation failed:', error.message);
+  }
+}
docs/error-handling.md (1)

83-100: Consider using a proper logger in the error handling example.

The PR checklist indicates "logger used instead of console.log" is satisfied, but this example uses console.error throughout (lines 84-86, 88-90, 92-94, 96, 98). While console.error is appropriate for documentation examples, consider using a logger to align with the project's logging standards and provide a better pattern for users.

📝 Logger-based error handling
 } catch (error) {
   if (error.code === "PROVIDER_NOT_CONFIGURED") {
-    console.error(
+    logger.error(
       "Vertex AI credentials not configured. Set GOOGLE_APPLICATION_CREDENTIALS.",
     );
   } else if (error.code === "VIDEO_POLL_TIMEOUT") {
-    console.error(
+    logger.error(
       "Video generation timed out. Try again or reduce video length.",
     );
   } else if (error.code === "VIDEO_INVALID_INPUT") {
-    console.error(
+    logger.error(
       "Invalid image format. Ensure PNG, JPEG, or WebP under 20MB.",
     );
   } else if (error.code === "VIDEO_QUOTA_EXCEEDED") {
-    console.error("Vertex AI quota exceeded. Check your billing and quotas.");
+    logger.error("Vertex AI quota exceeded. Check your billing and quotas.");
   } else {
-    console.error("Video generation failed:", error.message);
+    logger.error("Video generation failed:", error.message);
   }
 }
docs/framework-integration.md (5)

1343-1343: Replace console.error with proper logging.

The PR checklist indicates logger usage instead of console methods. Consider using a logger in the example to demonstrate best practices.

📝 Use logger
-    console.error("Video generation error:", error);
+    // Use appropriate logging in production
+    logger.error("Video generation error:", error);

1344-1346: Type-safe error message access.

Accessing error.message without verifying the error is an Error instance could fail if the caught value is not an Error object.

🔒 Safe error handling
     return NextResponse.json(
-      { error: error.message || "Video generation failed" },
+      { error: error instanceof Error ? error.message : "Video generation failed" },
       { status: 500 },
     );

1398-1398: Type-safe error message access.

Directly accessing err.message without type checking can throw if the caught value is not an Error object.

🔒 Safe error handling
-      setError(err.message);
+      setError(err instanceof Error ? err.message : "Video generation failed");

1495-1495: Replace console.error with proper logging.

The PR checklist indicates logger usage instead of console methods. Consider using a logger for consistency with project standards.

📝 Use logger
-    console.error("Video generation error:", error);
+    // Use appropriate logging in production
+    logger.error("Video generation error:", error);

1496-1496: Type-safe error message access.

Directly accessing error.message without type checking can fail if the error is not an Error instance.

🔒 Safe error handling
-    res.status(500).json({ error: error.message });
+    res.status(500).json({ 
+      error: error instanceof Error ? error.message : "Video generation failed" 
+    });
README.md (1)

44-57: Feature list expansion is comprehensive and well-organized.

The expanded bullet list provides clear descriptions and links for all major features including Video Generation, making it easy for users to discover capabilities.

Note: Static analysis suggests "custom trained models" (line 52) could be hyphenated as "custom-trained models" for grammatical precision, but this is optional.

docs/sdk/api-reference.md (1)

212-221: Video result structure is comprehensive.

The video field in GenerateResult provides:

  • Raw video data as Buffer
  • Media type for format identification
  • Useful metadata (duration, dimensions, model)

Minor observation: height is marked as optional in dimensions (line 218), which seems unusual since videos typically have both width and height. This might be intentional for some edge case, but worth verifying.

docs/reference/provider-feature-compatibility.md (1)

34-35: Table header updated correctly for Video Gen column.

The new "Video Gen" column is properly integrated into the feature matrix header structure.

docs/dynamic-models.md (1)

14-14: LGTM! Clear and concise documentation of video generation capability.

The addition accurately documents the new Veo 3.1 video generation feature and fits naturally within the dynamic model system overview.

docs/factory-pattern-architecture.md (1)

538-764: Documentation contains significant inaccuracies that do not match the actual implementation.

The documented architecture and class structure do not align with the codebase:

  • Class name mismatch: Documentation shows VideoGenerationHandler class, but the actual implementation uses generateVideoWithVertex() function
  • Error class mismatch: Documentation references VideoGenerationError, but implementation provides VideoError
  • Type name mismatches: Documentation uses VideoGenerationOptions and VideoResult, but implementation defines VideoOutputOptions and VideoGenerationResult
  • File path mismatch: Documentation indicates src/lib/handlers/videoHandler.ts, but actual implementation is in src/lib/adapters/video/vertexVideoHandler.ts
  • Architecture mismatch: Documentation shows a class-based architecture with VideoGenerationHandler integrated into VertexAIProvider, but the actual implementation uses standalone functions

The error codes (VIDEO_GENERATION_FAILED, VIDEO_POLL_TIMEOUT, VIDEO_INVALID_INPUT) and polling constants do exist and match documentation, but the core architectural patterns shown in the code examples are incorrect and will mislead developers.

Likely an incorrect or invalid review comment.

docs/provider-comparison.md (1)

15-15: LGTM! Clear provider capability indication.

The new "Video Gen" row clearly shows Veo 3.1 support for Vertex AI while marking other providers as unsupported. The table formatting is consistent with existing rows.

11-31: No issues found. The example correctly uses result.video.data to access the video buffer, which matches the documented API structure and is consistently used throughout all examples in the codebase.

docs/configuration.md (1)

212-212: Verify the Video Generation Guide link exists.

Same issue as in cli-reference.md - the link to features/video-generation.md should be verified.

This verification was already requested for cli-reference.md. The same shell script can verify both references.

docs/troubleshooting.md (1)

62-72: LGTM - Comprehensive troubleshooting coverage.

The troubleshooting section provides clear error codes and actionable solutions for common video generation issues. The table format makes it easy to scan for specific problems.

Good practices observed:

  • Mentions both GOOGLE_VERTEX_PROJECT and GOOGLE_CLOUD_PROJECT as alternatives (line 70)
  • Documents automatic provider switching behavior (line 69)
  • Includes specific technical limits: PNG/JPEG/WebP, 20MB size, 1-2 minute generation time (lines 67-68)
docs/tutorials.md (2)

107-107: The Video Generation Guide (docs/features/video-generation.md) exists in the repository. The reference on line 107 is valid and will not result in broken links.


43-50: This review comment is inaccurate. GOOGLE_VERTEX_LOCATION is already documented in the troubleshooting guide at line 33 under "Model not available in region," which explicitly mentions updating GOOGLE_VERTEX_LOCATION when models are unavailable in a region. Additionally, API reference documentation (docs/getting-started/api-reference.md:1459) clarifies that GOOGLE_VERTEX_LOCATION is optional with a default value of us-east5, so the variable is appropriately documented as part of the prerequisites.

Likely an incorrect or invalid review comment.

docs/framework-integration.md (1)

1284-1565: No duplication found. The "Video Generation Integration" section appears only once in the document at line 1284. The AI-generated summary's claim of duplicate sections is incorrect.

Likely an incorrect or invalid review comment.

README.md (1)

40-40: Video Generation feature addition looks good.

The new Video Generation with Veo entry is well-documented with clear description and guide link.

docs/index.md (2)

40-40: Video Generation feature addition looks good.

The new Video Generation with Veo entry is properly documented with clear description and guide link appropriate for the internal documentation structure.


44-57: Feature list expansion is comprehensive and well-structured.

The expanded bullet list effectively documents all major features with proper relative paths for the docs directory structure.

docs/performance-optimization.md (2)

537-802: No action required — this section appears only once in the file.

The search confirms only a single occurrence of the "## 🎥 Video Generation Performance Optimization" header at line 537. There is no duplication in the document. The AI-generated summary's claim of duplicate content is incorrect.

Likely an incorrect or invalid review comment.


811-811: No action needed — the Video Generation Guide link appears only once in the file at line 811. No duplication exists.

docs/testing.md (3)

242-311: SDK test structure looks comprehensive.

The TypeScript test examples cover key scenarios:

  • Basic video generation from image
  • Error handling for invalid input
  • Audio support validation

The tests use appropriate assertions for Buffer data, media types, and metadata. The error test correctly validates that video generation without an image input throws VIDEO_INVALID_INPUT.


313-343: CLI test examples are well-structured.

The bash tests demonstrate:

  • Basic video generation with file validation
  • ffprobe usage to verify valid video format
  • Configuration options (resolution, length, aspect ratio, audio)
  • Error handling verification using grep

The use of ffprobe for format validation is a solid approach for integration testing.


382-429: Integration test structure is well-designed.

The bash script provides a complete end-to-end testing example:

  • Proper environment setup for Vertex AI
  • Basic video generation test with file existence validation
  • HD video test with ffprobe resolution verification
  • Cleanup to remove test artifacts
  • Error handling with set -e

The 3-minute timeout (line 403) is appropriate given video generation typically takes longer than text generation.

docs/sdk/api-reference.md (3)

154-154: GenerateOptions extension is well-designed.

The output configuration cleanly separates:

  • format for structured output (existing feature)
  • mode to distinguish text vs. video generation
  • video options only when mode is "video"

This design avoids confusion between different output types and keeps the API surface intuitive.

Also applies to: 171-177


296-331: Video generation example is clear and complete.

The example demonstrates:

  • Loading an image as input
  • Configuring video options (resolution, duration, aspect ratio, audio)
  • Saving the generated video
  • Accessing metadata

The note about Vertex AI requirements and the reference to the feature guide provide helpful context for users. The example is consistent with the testing documentation.


182-189: VideoOutputOptions interface definition is correct but documentation has incomplete scope.

The interface properly constrains options to Veo 3.1's supported values:

  • Resolution limited to 720p/1080p ✓
  • Length constrained to 4, 6, or 8 seconds ✓
  • Aspect ratios for portrait/landscape ✓
  • Audio toggle with sensible default ✓

Validation logic is comprehensive and working correctly.

However: The current documentation doesn't mention workflow-specific constraints. Per Google's Veo 3.1 docs, reference-image-to-video workflows may have restrictions (e.g., 8 seconds only, limited aspect ratios in some variants). If this feature is planned, update the documentation to clarify which options apply to which workflows.

@coderabbitai Response for your nitpick comments:

  1. Basic generation uses output mode to catch up on default model and provider, this reduces the hassle of defining model and provider being user friendly.
    Last 2: The README.mdand sdk/api-reference.md items were just observations that don't require changes

@Rahul-2903-juspay, thank you for the clarification!

  1. Output mode defaults: I understand the design rationale — using the output mode to automatically select appropriate defaults for model and provider is a good user experience optimization, reducing configuration overhead for basic use cases.

  2. Observations: Noted that the README.md and sdk/api-reference.md items were informational observations and don't require any action.

I appreciate you taking the time to explain the design decisions. The documentation looks comprehensive and well-structured! 🎉
