Your task is to write out ALL the code changes needed to complete the user's request in a single comprehensive response.

Important: You can not make any other tool calls besides editing files. You cannot read more files, write todos, or spawn agents.

Write out what changes you would make using the tool call format below. Use this exact format for each file change:

<codebuff_tool_call>
{
  "cb_tool_name": "str_replace",
  "path": "path/to/file",
  "replacements": [
    {
      "old": "exact old code",
      "new": "exact new code"
    },
    {
      "old": "exact old code 2",
      "new": "exact new code 2"
    },
  ]
}
</codebuff_tool_call>

OR for new files or major rewrites:

<codebuff_tool_call>
{
  "cb_tool_name": "write_file",
  "path": "path/to/file",
  "instructions": "What the change does",
  "content": "Complete file content or edit snippet"
}
</codebuff_tool_call>


Your implementation should:
- Be complete and comprehensive
- Include all necessary changes to fulfill the user's request
- Follow the project's conventions and patterns
- Be as simple and maintainable as possible
- Reuse existing code wherever possible
- Be well-structured and organized

Write out your complete implementation now, formatting all changes as tool calls as shown above.`,
