Question

Output a project based on HTML, css and js only, which will have a chat interface for Gemini API. the main features is that, it will have datastructures which will hold data and checkpoints, divided into many categories.

-Memory: Small summary string, and its value contains detailed information that the model already stored. The model will have the summary passed with each iteration, and the model can select the index for the memory to fetch it if required.
-Immediate reasoning chain: Holds steps for continuous reasoning for a single reply. will automatically be passed on during each iterative reasoning process.
-Goals: COntains the goals and whatever, that the model has already stored in the beginning, to verify the final output. this will automatically be passed to the model. So, the model will think that it is outputting the final answer, but it wont be. this will be passed for verification, also, all the immediate reasoning data structure chain will also be passed so that it can verify. Then only it will be the final output.

-it will have a code execution environment that explicitly uses javascript only, and has proper and complete internet access. it can use that js environment as much as required. ALso, that will be the script directly executing inside the browser. No sandbox nothing. Directly in the browser. make sure that any kind of output from the js will be passed on to the model, or, the model can choose to include the output of the js directly to the final answer, using a variable in the final answer, which will be replaced by the project's script during the rendering.

-it will also have the canvas feature, which will display the html file for display. it can use that during the intermediate reasoning process too.

-also, the model's internal thought process that is chain of thoughts is different. there will also be a different iterative reasoning and tool use that is defined in this prompt, that the model must use. include proper prompts for each steps. Make sure you let the LLM know that, whatever there is available is inside the 'External Tools system'.

Design principle:- Swiss, minimalist, monochrome, mandatory geist fonts fetched from the internet.

Make sure that the identification for the models intention to use different tools is robust, the handling of everything is robust, the LLM would be aware of whats happening, and there must be 5 keys input for different keys, for when one API key has reached the rate limit. we have paid for 5 API keys. API keys will be stored in the localstorage so that each user has their own.

the thing is also that, make it stream and show output and make the page responsive in a sense. professional design with no emoji or stuff.

Output an html file, one css file, and many js files. For now, output only css and html file. we want this to be extremely detailed.

Answer 1

Below are the two files you asked for — a fully wired HTML shell and a comprehensive CSS stylesheet. They implement the Swiss/minimalist, monochrome UI, load Geist fonts from the internet, define the complete layout (chat, data structures, tools, execution, canvas/preview), streaming affordances, responsive behavior, and robust placeholders for the JS modules you’ll add next (Gemini client, tool router, memory/goals/checkpoints handling, streaming, code execution with unsandboxed iframe, etc.).

Everything JS-related is referenced but not shipped, per your request.

  <!-- Coordinator & Step Prompts (LLM-visible; JS will inject them) -->
  <template id="prompt-coordinator">
SYSTEM:
You are the Coordinator. You orchestrate tool usage to produce a correct, verified final answer.

CONTEXT PACK:
- goals: <GOALS[]>
- memory_summaries: <MEMSUMS[]>
- immediate_reasoning_chain (IRC): <IRC_STEPS[]>
- checkpoints: <CHECKPOINTS{}>

POLICY:
- Keep chain-of-thought PRIVATE; never reveal it verbatim to user. Maintain brief reasoning summaries only.
- For data retrieval/computation/drawing, prefer calling an External Tool from the "External Tools system".
- Use goals to verify candidate answers. If mismatch, iterate until consistent.
- When code execution is needed, use js.run (unsandboxed). Capture outputs for inclusion via template variables like {{varName}}.
- If HTML is to be rendered or used during reasoning, use html.preview to update the preview frame.
- If visual drawing helps, use canvas.render.
- Use memory.store / memory.get / goals.get / irc.append / checkpoint.save as required.
- Stream tokens when available; provide incremental, user-visible content without exposing private chain-of-thought.

OUTPUT CONTRACT:
- For tool usage, respond ONLY with a single fenced tool call:
  ```tool:<name>
  {json}

For user-visible text, provide clear, concise prose; interpolate any captured variables (e.g., {{analysis}}) which the app will replace on render.

VERIFICATION:

Before finalizing, compare draft answer against goals; if gaps remain, iterate tools again. </template>
<template id="prompt-js-run">

SYSTEM: You are executing JavaScript directly in-page. Return compact, serializable output.

CONSTRAINTS:

Avoid blocking UI. Prefer async patterns.
Return structured data (JSON) or concise strings.
Any console output will be captured.

RETURN:

A single JSON-serializable value (or plain string). </template>
<template id="prompt-web-fetch">

SYSTEM: You are performing an HTTP(S) fetch. Provide method, headers, and optional body. Decide if response should be text or JSON. </template>

<template id="prompt-verify"> SYSTEM: You are verifying a candidate answer against known GOALS and IRC notes. Return a short verdict: PASS or FAIL and a one-paragraph rationale. Do not include private chain-of-thought details. </template> </body> </html> ```

If you want, I can now generate the JS modules to make this fully functional (Gemini streaming, key rollover, tool router, unsandboxed JS execution with captured outputs, canvas ops, HTML preview loading, memory/goals/IRC storage, and verification passes).

Output a project based on HTML, css and js only, ...
