15-20: Add explicit Optional type annotations.Per PEP 484, parameters with
Nonedefaults should useOptional[T]type hints. The current implicit optional style is deprecated.🔎 Proposed fix
Add the import at the top of the file:

36-41: Fix the python-compile hook to actually check committed files.The
pass_filenames: falsesetting prevents this hook from receiving the list of files being committed, so it won't compile anything. This makes the hook ineffective.🔎 Proposed fix
- id: python-compile name: Python compile check entry: python -m py_compile language: system files: \.py$ - pass_filenames: false.pre-commit-config.yaml-43-49 (1)
43-49: Fix the import-check hook logic.The command
python -c "import __init__"attempts to import a module literally named__init__, which won't verify the actual Python files being committed. This hook won't catch import errors in your code.🔎 Proposed fix
Consider one of these approaches:
Option 1: Check if files can be imported as modules
- id: import-check name: Python import check - entry: python -c "import __init__" + entry: bash -c 'for file in "$@"; do python -c "import sys; sys.path.insert(0, \".\"); exec(open(\"$file\").read())" || exit 1; done' -- language: system files: \.py$ - pass_filenames: false exclude: ^tests/Option 2: Import the package root (simpler but less thorough)
- id: import-check name: Python import check - entry: python -c "import __init__" + entry: bash -c 'python -c "import nodes; import core; import web"' language: system files: \.py$ pass_filenames: false exclude: ^tests/Makefile-46-51 (1)
46-51: Test target has shell compatibility and import issues.
- The
**glob pattern requires bash withglobstarenabled; it won't work in POSIX sh or older bash.import __init__is invalid Python syntax for testing package imports.🔎 Proposed fix

37-48: Update GitHub Actions to latest versions and use setup-python's built-in pip cache for cross-platform compatibility.Use
actions/setup-python@v6withcache: 'pip'to handle pip caching instead of manually managing the cache step.

Update torch to at least 2.6.0 to patch critical remote code execution vulnerability.
The dependency torch>=2.0.0 permits installation of versions ≤2.5.1, which are affected by critical CVE-2025-32434 patched in version 2.6.0. This RCE vulnerability has a CVSS 9.3 rating and is categorized as critical. Update the PyTorch requirement to torch>=2.6.0 immediately; all previous versions up to 2.5.1 remain vulnerable.
Additionally, other packages are significantly outdated: Pillow (latest: 12.0.0, requirement: 10.0.0), aiohttp (latest: 3.13.2, requirement: 3.9.0), and opencv-python (latest: 4.12.0.88, requirement: 4.8.0).

- def _enhance_prompt_with_gemini(self, prompt: str, api_key: str) -> str: + def _enhance_prompt_with_gemini(self, prompt: str) -> str: """Enhance prompt using Gemini for better image generation"""And update the call site at lines 230-232:
full_prompt = self._enhance_prompt_with_gemini( - full_prompt, api_key + full_prompt )
233-234: Addstacklevelto warningsWithout
stacklevel=2, the warning will point to this line rather than the caller's context, making debugging harder.🔎 Proposed fix
except Exception as e: - warnings.warn(f"Failed to enhance prompt: {str(e)}") + warnings.warn(f"Failed to enhance prompt: {e!s}", stacklevel=2)Apply the same fix to line 473:
- warnings.warn(f"Prompt enhancement failed: {str(e)}") + warnings.warn(f"Prompt enhancement failed: {e!s}", stacklevel=2)

6-6: LGTM! Torch vulnerability addressed.The update to
torch>=2.6.0correctly addresses the critical CVE-2025-32434 (RCE vulnerability) mentioned in the previous review.nodes/config/settings.py (1)
52-141: LGTM! Robust status display implementation.The
show_statusmethod correctly handles both JSON and text formats, provides comprehensive provider information, and includes proper error handling. The broad exception catching at Line 139 is appropriate for a diagnostic node that should gracefully display errors rather than crash.Makefile (1)
1-78: LGTM! Comprehensive development automation.The Makefile provides well-organized targets for development workflow (format, lint, type-check, test, build, clean) with clear help documentation and proper dependency chains. The static analysis warnings about help target length and missing "all" target are minor conventions that don't impact functionality.
nodes/utils/image_input.py (1)
92-112: LGTM: Type consistency issue resolved.The past review comment about mixing tensors and PIL images has been addressed. The code now consistently converts all inputs to PIL before adding to
all_images(lines 98-101 for individual images, lines 106-110 for batch images).server.py (3)
186-253: Well-implemented webhook signature verification.The signature verification logic properly handles:
- Stripe's t/v1 format with timestamp validation (5-minute window)
- Constant-time comparison to prevent timing attacks
- Provider-specific verification (Coinbase, generic HMAC)
- Malformed signature part handling
280-310: Good defensive coding for amount parsing.The safe conversion of amount strings to floats with try-except blocks (lines 280-285 and 303-308) prevents crashes from malformed payment data.
367-374: Excellent atomic write implementation.Using a temporary file with explicit
fsync()followed by atomic rename prevents corruption and race conditions in concurrent webhook logging.core/image_utils.py (2)
157-163: Exception wrapping is appropriate here.The broad exception catch at line 162 is justified because it wraps any base64 decode/image open errors into a ValidationError with context. This provides a clean API boundary.
359-369: Note: Wrapper function differs from class method.The
resize_for_apiwrapper (lines 359-369) uses a simple max_dim approach, whileImageConverter.resize_for_api(lines 166-213) uses provider-specific limits. This may cause inconsistencies if callers expect provider-aware resizing.Verify that callers of the wrapper function at lines 359-369 don't need provider-specific size limits. If they do, consider updating the wrapper to delegate to
ImageConverter.resize_for_apiinstead of reimplementing the logic:def resize_for_api(image: Image.Image, max_dim: int = 1024) -> Image.Image: """Resize image for API submission, maintaining aspect ratio.""" # Option 1: Use a custom provider with the max_dim # Option 2: Just use ImageConverter with default provider return ImageConverter.resize_for_api(image, provider="openai")Or add a provider parameter to the wrapper for consistency.
nodes/image/imagen.py (3)
477-529: Good backward compatibility handlingThe response processing correctly handles both the new
generated_imagesformat and the legacycandidatesformat. Thehasattrchecks provide safe attribute access.Minor: Consider moving
import base64(line 512) to the module level for consistency.
531-534: LGTM!Standard ComfyUI pattern for cache invalidation based on parameter changes.
270-277: Move client creation outside the retry loop and verifygenerate_imagesAPI signatureGoogle Cloud API clients should be long-lived and reused; creating a new client for each request wastes resources since connection pooling is done at the client level. If this client is indeed instantiated inside a retry loop, move it outside and reuse it across attempts.
Additionally, verify the
generate_imagesmethod signature. In the current Google Gen AI SDK, safety settings are passed inside the config object asconfig=types.GenerateContentConfig(safety_settings=[...]), not as a separate parameter. Confirm this matches yourgenerate_imagescall.

Fix the YAML syntax error by using proper string delimiters — backticks are not valid in YAML.
The workflow fails with "mapping values are not allowed here" at line 115 because the body value uses backticks () with unescaped colons in the content. Backticks are JavaScript syntax, not YAML. Use double quotes around the entire string, or replace the backticks with a pipe block scalar (|`) and properly indent the content:
Option 1 (quoted):
body: "👋 Welcome @${creator}! Thanks for opening your first issue in uz0/comfy! ..."Option 2 (block scalar):
body: |

Upgrade actions/stale to v10 (or v9 minimum).
Version 9 updated the runtime to Node.js 20, and version 10 upgraded to Node.js 24. Node 16 has reached its end of life, with workflows containing actions running on Node 16 displaying warnings starting October 23rd. The current official documentation shows v10 in all examples. Using actions/stale@v8 will trigger deprecation warnings and should be updated.
