Agent systems, without the fog.

This is where the fun gets serious: context, memory, tool authority, MCP, A2A and multi-agent delegation. The goal is not to collect protocol names. It is to know who owns each decision when the system is busy, wrong or under pressure.

1

Start with the harness

A bounded loop, a clear stop condition and authority you can explain.

2

Understand the boundary

MCP and A2A connect systems; they do not replace policy or responsibility.

3

Operate the system

Every handoff needs evidence, identity, limits and a failure path.
