Windsurf

3.1 Understanding the Project (Codebase Awareness)

The most important feature in Windsurf is that the assistant does not deal only with the current file; it can reference other files and read relevant parts of the repository to form a “picture” of the project. The practical benefit appears in tasks such as:

• Updating the API interface and automatically modifying calls across multiple files.
• Tracing the definition of a function/type across import paths, and suggesting fixes at usage sites.
• Understanding the project layers (Controller/Service/Repository) and suggesting the most appropriate place to make the change.

3.2 Agentic Editing Mode (Agentic Editing / Multi‑file Edits)

Instead of settling for a text‑only answer, Windsurf can generate multiple changes across files, then present them to you for review. This greatly shortens many “refactoring” tasks or adding a small feature that requires cross‑cutting edits.

How do you benefit? For example, ask: “Add a new endpoint with tests, and update the documentation,” then review the resulting bundle before approving it.

3.3 In‑Editor Chat

A chat interface tied to the coding context that allows you to ask questions such as: “Why is this test failing?” or “Explain to me the execution path of this function.” The tool benefits from context (file/selection/search results) instead of relying on lengthy copy‑paste.

3.4 Smart Code Completion (Code Completion)

Windsurf supports code completion while typing in a style similar to modern completion tools. In practice, you’ll find it useful for:

• Quickly writing repetitive boilerplate.
• Completing API calls or handling types in TypeScript.
• Suggestions in similar functions within the context of your project.

3.5 Contextual Actions on a Specific Selection (Selection‑based Actions)

You can select a portion of the code and then request: “Tur…”
