🤌 CWC is non-agentic, but why?
Large language models (LLMs) are trained on vast datasets targeting many use cases. For code generation, a model's training involves analyzing millions of simulated problem-solving flows, such as arriving at an accepted answer from a StackOverflow question. For the purpose of agentic coding, models are trained on an additional layer of data that simulates gathering context and planning next steps.
Because the model is only as smart as examples it has seen in its pre-training, the possible coverage of real-world coding scenarios when approached at a high level is fundamentally limited.
Therefore, CWC is designed to align with LLMs' true capabilities—that is, code generation in a controlled signal-to-noise ratio environment. Controlled by you, the engineer.
💅 The workflow
Select folders and files for context, enter prompt, pick edit format and send message via...
- new chat—to continue in the connected browser
- API call—to use a model provider of choice
Constructed message consists of the user's prompt, edit format instructions, and the selected context, as shown in the example:
Implement a subtract function.
<system>
Whenever proposing a new or updated file use the Markdown Code Block syntax. Each code block should be a diff patch. Don't use XML for files.
</system>
<files>
<file path="src/calculator.ts">
<![CDATA[
export const addNumbers = (a: number, b: number) => a + b;
]]>
</file>
</files>
Implement a subtract function.
<system>
Whenever proposing a new or updated file use the Markdown Code Block syntax. Each code block should be a diff patch. Don't use XML for files.
</system>
Note
The prompt and edit format instructions are repeated after the context for better accuracy.
Once the response is generated, a built-in parser extracts code blocks with suggested edits for one-click multi-file changes integration.
Install the open-source Connector in your browser and never copy & paste again.

Note
All web page interactions of submitting the message are handled by the content script.
Tip
With the browser extension you can include markdown-parsed websites in context! Go to target website, click the extension's icon in the browser's toolbar and click Enable for context. The website will appear in the context panel immediately, ready for selection like any other folder or file in the workspace.
Important
Legal disclaimer: The placed Apply response button is not a means of automatic output extraction, it's an alias for the original copy to clipboard button. The extension's sole purpose of chat initialization is complete once the first message is submitted.
Anything CWC can do in chatbots, it can do calling model providers directly from the editor.
🛠️ Edit Context
Modify, create or delete files based on natural language instructions.
🛠️ Code Completions
Get accurate code-at-cursor from state-of-the-art reasoning models.
🛠️ Intelligent Update
Handle the compact "truncated" edit format and malformed diffs.
🛠️ Commit Messages
Generate meaningful summaries of changes adhering to your style.

Code Web Chat operates exclusively on your machine. Your code and instructions are sent directly to chatbots via editor-browser communication channel run on local Websockets. For API tools, model providers are called directly.
If you have a question, or want to help others, you're always welcome in our community.
