Three layers, one repo: a tour of google/adk-recipes
Summary
- Google introduced google/adk-recipes, a restructured single source of truth repository powering Google Cloud's Agents CLI, Agent Garden, and Gemini Enterprise app.
- The repository is organized into three top-level layers: core/ for reference patterns, plugins/ for installable vertical skills like retail, and contrib/ for deployable services.
- Every recipe contains machine-readable manifests and AGENTS.md instructions designed specifically for AI coding assistants to discover, scaffold, and validate solutions.
- The core layer includes Horizon, a reference harness for long-horizon memory agents, while the retail plugin layer provides vector search product discovery and virtual try-on skills.
Why it matters
The adk-recipes repository streamlines agent development by standardizing agent patterns, vertical skills, and deployments into a machine-readable format built for AI coding assistants.
