Windsurf Wave 10
The presentation of this update was spread over several days, which allowed for more blog posts and YouTube videos – this was done for Wave 8 and probably works well from a marketing perspective.

A "Planning Mode" button appeared - this is a correct and obvious step (a response to MCP https://www.task-master.dev/). First, the task is broken down into subtasks using a "thinking" model, and then the coder (a simpler model) doesn't get confused about what to do, but follows the steps (it's also cheaper for them this way). Works well with memory.

Again, there were MCPs. Now they've been redesigned into one button to launch a managed Chromium instance so that the chat can directly see what's happening in it.

One cluster has been launched in Europe. Now the PCW metric is used not only for autocompletions in the editor but also to assess how the chat agents are performing.

Percentage of Code Written (PCW)

PCW — is the percentage of code written with the help of AI tools. Helps assess the real benefit of AI in development and excludes metric inflation (unlike competitors' "adoption rate"). Only code that makes it into a commit is considered (unsuccessful edits are not counted), while the metric does not take into account architecture, debugging, or reviews.

• W — bytes of code from Windsurf (Tab, Cascade).
• D — bytes of code written manually.
• PCW = (100 × W) / (W + D).
