Middleware hooks attach at three layers of the tool execution loop: Generate, Model, and Tool. Pre-built middleware covers retries with exponential backoff, model fallbacks to alternative providers, tool approval gates for human-in-the-loop workflows, skill injection from SKILL.md files, and scoped filesystem access. Custom middleware follows a simple name-plus-factory contract, and multiple middleware can be stacked in explicit order. A content filter example demonstrates how to enforce business rules deterministically in ~20 lines of Go code. The Genkit Developer UI supports inspecting and tracing middleware execution. ## Full article daily.dev links to this article rather than hosting it.
