Windsurf Upgrades to VSCode 1.110 with Agent Plugins

VSCode 1.110 Base Upgrade Brings Agent Plugins

Windsurf updated its underlying editor to VSCode 1.110 with the release of version 1.9600.1002, aligning the IDE with Microsoft's February 2026 release of the Visual Studio Code base. The upgrade is notable primarily for the addition of Agent Plugins, an experimental framework that enables AI agents to control the browser directly from within the editor. This capability opens the door to agentic workflows that span both code and live web interfaces — for instance, an agent that writes a form handler, then navigates to a staging URL to verify the form submits correctly, all without leaving Windsurf.

Alongside Agent Plugins, the VSCode 1.110 base introduces several improvements that Windsurf users benefit from immediately:

• Session memory improvements that allow agents to maintain better context across long-running tasks
• A new Agent Debug panel that surfaces internal agent state, making it easier to diagnose and interrupt stuck or misbehaving agent runs
• General editor stability and performance refinements from two months of upstream VSCode development

Granular Quota Cost Metrics Replace Dollar-Sign Indicators

The most immediately visible change for most Windsurf users is the replacement of dollar-sign cost indicators with granular quota cost metrics. Where the IDE previously showed a rough dollar amount per AI action, it now displays how much of the user's daily and weekly quota each action consumes.

This change is a direct response to community feedback following Windsurf's March 2026 transition from a credit-based billing model to a quota-based system. The quota system allocates users a fixed volume of compute per day and per week, and the lack of fine-grained visibility into how individual actions drew down that quota was a persistent source of confusion. With the new metrics, users can see at a glance whether a given Cascade task costs a small or large fraction of their daily allowance before committing to it — enabling more intentional use of high-cost actions like multi-file refactors or long-running agent sessions.

Large Repository Performance Improvements

Windsurf 1.9600.1002 also includes performance improvements specifically targeting large repositories. Windsurf has previously invested in scaling its codebase indexing and context retrieval for large monorepos, and this release continues that work with optimizations aimed at reducing latency when Cascade navigates, searches, or modifies files in codebases with tens of thousands of files.

The specific improvements are not enumerated in detail in the changelog, but the focus on large-repo scenarios signals continued investment in making Windsurf competitive for enterprise-scale development environments.

Diff Zone Fix for Editor Reliability

A targeted bug fix addresses an issue with diff zones — the inline display regions that show proposed changes from Cascade before the user accepts or rejects them. The fix resolves a case where diff zones could render incorrectly or become unresponsive, which required a manual editor reload to clear. While not a headline feature, this fix improves the day-to-day reliability of the core Cascade code-suggestion workflow that most Windsurf users interact with dozens of times per session.
