demohouse/mutimedia/backend/pyproject.toml:1

• The project name contains 'veadk' but the directory path uses 'mutimedia' (should be 'multimedia'). This inconsistency suggests a typo in the directory structure.
  demohouse/mutimedia/backend/app/release-agent/src/release_agent/tools/video_combine_vod.py:1
• Missing await keyword for async function call. This will assign a coroutine object instead of the resolved URL value.
  demohouse/mutimedia/backend/app/release-agent/src/release_agent/tools/video_combine.py:1
• Error message states "10GB" but the actual limit check at line 131 is 512MB (max_file_size = 512 * 1024 * 1024). The error message should match the actual limit.
  demohouse/mutimedia/backend/app/market-agent/src/market_agent/hook/format_hook.py:1
• This creates a list of boolean True values, but line 93-96 attempts to zip it with resources and check boolean values. Should be: image_indices = [i for i, (_, is_image, _) in enumerate(is_images_results) if is_image] to get the actual indices.
