CWC is a free and privacy-fist toolkit for AI coding with static context. Start in VS Code (Cursor, Antigravity, VSCodium, etc.), then continue in ChatGPT, Gemini, Claude, etc. or Bring Your Own Key and stay in the editor!

Tip

Elevate your workflow with smart workspaces (called projects, gems, or spaces).

Introduction

CWC provides developers with a complete and free toolkit for pair programming with AI that augments, rather than replaces, traditional coding.

Privacy

CWC operates 100% on your machine—no code, prompts or usage data are collected.

Static context

CWC constructs unified prompts with all relevant files and instructions, so the model has everything it needs from the start. Steer it with examples, focus its attention on specific code, and make simple instructions just work!

Prompt types

CWC helps with all common use-cases like multi-file editing, planning, generating code at cursor or commit messages.

Edit files (click to expand)

Implement new features, fix bugs and refactor code across many files.

# Files

[SELECTED FILES]

# Output formatting
Whenever showing a new, updated, renamed, or deleted file, provide a brief explanation, then print the path in a markdown heading (e.g. ### New file: `src/examples/hello.py`, ### Updated file: `src/examples/hello.py`, ### Renamed file: `src/examples/hello.py` (old) `src/welcome.py` (new), ### Deleted file: `src/examples/hello.py`), followed by a markdown code block showing the original and updated code snippets with Git-style merge conflict syntax. Example:

[EXAMPLE]

---

[PROMPT]

Ask about files

Plan features or get explanations.

# Files

[SELECTED FILES]

---

[PROMPT]

Code at cursor

Quality TAB completions from SOTA reasoning models.

# Files

[SELECTED FILES]

- File `[ACTIVE FILE PATH]`:

```
[PREFIX]<missing_text>[PROMPT]</missing_text>[SUFFIX]
```

# Output formatting

Your response must begin with a markdown heading identifying the file and the cursor position, followed by a markdown code block containing the replacement text, followed by a brief explanation. The heading must be: "### Code at cursor: `[ACTIVE FILE PATH]` (ROW:COL)". Always refer to the symbol "<missing_text>" as "cursor position" and "replacement" as "completion". Example:

[EXAMPLE]

---

Find correct replacement text for the <missing_text> symbol.

Prompt caching

CWC orders context files by modification and selection recency. This, combined with instructions placement at the message's very end effecively utilizes prompt caching across tasks.

Enabling autofill

Install the browser extension and never copy and paste again.

Important

The Apply response button placed under responses is not a means of automatic output extraction, it's an alias for the original copy to clipboard button. Review the content script to learn about implementation details.
