# Gemini Feedback
Get feedback from Gemini API on a diagram image.
## Usage
```
/gemini-feedback <path-to-image> [context]
```
## Instructions
When this command is invoked:
1. Read the image file at the provided path
2. Call the Gemini API to get feedback on the diagram
3. Use this Python snippet to call Gemini (uses the newer `google-genai` package):
```python
import base64
import os
from google import genai
client = genai.Client(api_key=os.environ['GEMINI_API_KEY'])
with open('<IMAGE_PATH>', 'rb') as f:
img_bytes = f.read()
prompt = '''Review this diagram for a textbook. Be concise and specific.
Context: <CONTEXT>
Please provide:
1. Overall assessment (1-2 sentences)
2. Specific issues to fix (be detailed about visual problems like alignment, overlapping, etc.)
3. Suggestions for improvement
'''
response = client.models.generate_content(
model='gemini-2.5-flash',
contents=[
prompt,
genai.types.Part.from_bytes(data=img_bytes, mime_type='image/png'),
],
)
print(response.text)
```
4. Replace `<IMAGE_PATH>` with the actual path provided
5. Replace `<CONTEXT>` with any context provided, or use "Technical diagram for ML/AI textbook"
6. Ensure GEMINI_API_KEY is set in environment
7. Run using: `uv run python -c "..."`
8. Present the feedback to the user
## Example
```
/gemini-feedback diagrams/generated/png/tool_use_generation.png "Diagram showing tool use interleaving in LLM generation"
```
