EF.Constant inlines a captured value as a SQL literal, EF.Parameter turns a literal into a SQL parameter.

Volatile.Read is an acquire load of one location.

An agent skill is a folder with a SKILL.md file that the agent loads on demand: only its name and description sit in the system prompt, the instructions arrive when a task matches, and bundled scripts run without ever entering context.

Since the September 2026 .NET SDKs (10.0.112, 10.0.401, 11 RC1), dotnet watch rejects browser-refresh WebSockets from unknown origins.

A coding agent refactors a component, renames a data-testid, and your Playwright suite goes red.
