Val Town Code SearchReturn to Val Town

26  - [x] File write as a code embed
27  - [x] str_replace as a diff view
28- [x] make image drop area invisible and bigger
29- [x] Give it all the code (except maybe .txt files) as initial context (like cursor sonnet max)
30- [x] I seem to have lost the delete file tool and instructions, try to find them back in history or re-create?

12- If a section of code that you're working on is getting too complex, consider refactoring it into subcomponents
13
14## Image Handling
15
16- When users upload images, carefully analyze them to understand their content
17- Reference specific details from the images in your responses
18- If multiple images are uploaded, consider their relationship to each other
19- For code-related images (screenshots, diagrams), extract relevant information and incorporate it into your solutions
20- For UI mockups or design images, use them as reference for layout and design, use the colors from the image
21- When images contain text or code, transcribe relevant portions as needed
22- If image content is unclear, ask clarifying questions about what the user wants you to focus on
23
24## Technical Requirements
95## Val Town Platform Specifics
96- **Redirects:** Use `return new Response(null, { status: 302, headers: { Location: "/place/to/redirect" }})` instead of `Response.redirect` which is broken
97- **Images:** Avoid external images or base64 images. Use emojis, unicode symbols, or icon fonts/libraries instead
98- For AI-generated images, use: `https://maxm-imggenurl.web.val.run/the-description-of-your-image`
99- **Storage:** DO NOT use the Deno KV module for storage
100- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods
