Taxonomy of agentic primitives in Amazon Quick

By · Published by Everything Blog

In short

The framework formalizes system architecture by decomposing agentic tasks into triggers, agents, capabilities, and execution boundaries. Triggers govern task timing and instruction delivery, falling into categories such as human conversation, agent delegation, scheduled routines, and external event signals. Furthermore, the model treats the underlying large language model as an interchangeable component, allowing a persistent learning agent to retain memory and adapt across varied environments.

Taxonomy of agentic primitives in Amazon Quick

Over the past year, as we built Amazon Quick, our agents went from answering questions to taking actions: scheduling meetings, running research, generating reports. As the system evolved, one problem kept resurfacing: there was no shared definition of the primitives that agentic work is built from. The same few ideas kept getting rebuilt under different names: an actor that does the work, a signal that starts it, a packaged procedure, and a memory that carries lessons forward. This repetition leaked into product design and onto the user.

Take the user who says “monitor my Slack channel and send me a daily digest”. Is that a new agent, a scheduled instruction to an existing one, a workflow, or a skill? These are different questions, but without a shared vocabulary they collapse into one confusing choice.

This post shares the taxonomy we converged on: one set of primitives found by decomposing agentic work into four plain questions: When?, What?, Who?, and How? Most of the framework stays invisible to end users by design,…
