AI-first code editor with Composer
Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionnano-bananaExecute the skills CLI command in your project's root directory to begin installation:
Fetches nano-banana from kkoppenhaver/cc-nano-banana and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate nano-banana. Access via /nano-banana in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Generate professional images via the Gemini CLI's nanobanana extension.
ALWAYS use this skill when the user:
Do NOT attempt to generate images through any other method.
gemini extensions list | grep nanobanana
gemini extensions install https://github.com/gemini-cli-extensions/nanobanana
[ -n "$GEMINI_API_KEY" ] && echo "API key configured" || echo "Missing GEMINI_API_KEY"
| User Request | Command |
|---|---|
| "make me a blog header" | /generate |
| "create an app icon" | /icon |
| "draw a flowchart of..." | /diagram |
| "fix this old photo" | /restore |
| "remove the background" | /edit |
| "create a repeating texture" | /pattern |
| "make a comic strip" | /story |
Note: Always use the --yolo flag to automatically approve all tool actions.
| Command | Use Case |
|---|---|
gemini --yolo "/generate 'prompt'" |
Text-to-image generation |
gemini --yolo "/edit file.png 'instruction'" |
Modify existing image |
gemini --yolo "/restore old_photo.jpg 'fix scratches'" |
Repair damaged photos |
gemini --yolo "/icon 'description'" |
App icons, favicons, UI elements |
gemini --yolo "/diagram 'description'" |
Flowcharts, architecture diagrams |
gemini --yolo "/pattern 'description'" |
Seamless textures and patterns |
gemini --yolo "/story 'description'" |
Sequential/narrative images |
gemini --yolo "/nanobanana prompt" |
Natural language interface |
--yolo - Required. Auto-approve all tool actions (no confirmation prompts)--count=N - Generate N variations (1-8)--preview - Auto-open generated images--styles="style1,style2" - Apply artistic styles--format=grid|separate - Output arrangement| Use Case | Dimensions | Notes |
|---|---|---|
| YouTube thumbnail | 1280x720 | --aspect=16:9 |
| Blog featured image | 1200x630 | Social preview friendly |
| Square social | 1080x1080 | Instagram, LinkedIn |

| Vertical story | 1080x1920 | --aspect=9:16 |
Default: gemini-2.5-flash-image (~$0.04/image)
For higher quality (4K, better reasoning):
export NANOBANANA_MODEL=gemini-3-pro-image-preview
# Modern illustration style
gemini --yolo "/generate 'modern flat illustration of developer coding at laptop, purple and blue gradient background, minimalist style, no text' --preview"
# Professional photography style
gemini --yolo "/generate 'professional editorial photo of coffee cup next to laptop on wooden desk, morning sunlight, shallow depth of field, no text' --count=3"
# Tech/abstract
gemini --yolo "/generate 'abstract visualization of neural network connections, dark background with glowing blue nodes, futuristic style' --preview"
gemini --yolo "/icon 'minimalist app logo for productivity tool' --sizes='64,128,256,512' --type='app-icon' --corners='rounded'"
gemini --yolo "/diagram 'user authentication flow with OAuth' --type='flowchart' --style='modern'"
All generated images are saved to ./nanobanana-output/ in the current directory.
After generation completes:
./nanobanana-output/ to find generated filesWhen the user asks for changes:
--count=3gemini --yolo "/edit nanobanana-output/filename.png 'adjustment'"--styles="requested_style" to the command| Problem | Solution |
|---|---|
GEMINI_API_KEY not set |
export GEMINI_API_KEY="your-key" |
| Extension not found | Run install command from setup section |
| Quota exceeded | Wait for reset or switch to flash model |
| Image generation failed | Check prompt for policy violations, simplify request |
| Output directory missing | Will be created automatically on first run |

Steps
Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
