Rider 2026.2 EAP 5: Code Quality Checks for Your AI Agents, and More.
Rider 2026.2 EAP 5 is now available, bringing a faster startup flow with the new non-modal Welcome screen and quality-check hooks for AI agents.
If you’re catching up on the 2026.2 EAP cycle, be sure to check out the blog posts we’ve already published about other updates unveiled so far, including WPF Hot Reload, the finding-tests skill for AI-assisted test generation, and the earlier EAP builds.
Quality-check hooks for Claude Code
Rider now ships quality-check hooks for Claude Code in any language supported by Rider.
Enable the skill in the Settings, and Rider will validate every change an agent makes before it’s allowed to continue, catching code issues, inspection findings, and even formatting inconsistencies. Errors will block the task from being marked complete, while warnings come back as feedback the agent can act on. You and your IDE set the quality bar, not the agent.
You can enable code quality hooks from Settings/Preferences | Tools | AI Agent Hooks. Rider will automatically configure the required hook entries for Claude Code.
Support for Codex is coming.
Easier access to Explain with AI
The Explain with AI action is now easier to discover when you need it most: while dealing with build errors and runtime exceptions. Instead of copying diagnostics into chat or manually describing what went wrong, you can trigger an AI explanation directly from the place where Rider surfaces the problem.
For .NET developers, this is especially useful because build output often combines Roslyn diagnostics, analyzer warnings, MSBuild issues, NuGet restore problems, and multi-targeting failures. Explain with AI helps turn noisy or context-dependent errors into a clearer explanation with likely causes and next steps, so you can move from failure to fix faster.
