This lane focuses on production-minded system concerns, which is one of the
main opportunities for this repository to stand apart from lighter agent
courses and cookbook repos.

## What belongs here

* Context engineering
* Protocol interoperability
* Evaluation
* Observability
* Reliability
* Safety and governance
* Deployment and operations

## Editorial intent

Pages in this lane should move beyond demos. The goal is to explain how agent
systems behave as real software systems with interfaces, traces, boundaries,
and operational tradeoffs.

## Current pages

* [Context Engineering](/systems/context-engineering): how systems write, select,
  compress, and isolate context for reliable multi-step work.
* [Agent Security And Prompt Injection](/systems/agent-security-and-prompt-injection):
  how teams contain untrusted inputs, dangerous tools, and external side
  effects in production-minded agent systems.
* [Agent UI Protocols And Generative UI](/systems/agent-ui-protocols-and-generative-ui):
  how AG-UI and A2UI separate user-facing interaction from tool and agent
  protocols.
* [Protocols And Interoperability](/systems/protocols-and-interoperability): how
  tool access, agent collaboration, and network discovery fit together.
* [Evaluation And Observability](/systems/evaluation-and-observability): how to
  measure capability, turn written intent into runnable evals, and explain
  failures in production-minded agent systems.

## Example starters

* [Weather MCP Server Starter](/systems/examples/weather-mcp-server-starter):
  a thin protocol-facing tool service sketch for future interop examples.
