Guide map

Start with a persona guide — Explorer, Builder, Operator, or Power user — or with the harness, a learning path, or the section that matches the job in front of you. The posts, articles, and repositories behind the pages are in Social references & inspirations.

Each card is a link. The pill is who that section is written for.

Sections

00 · Foundations

What an agent is, the loop, and how memory, tools, and planning share the work.

01 · Agent patterns

The harness is the frame. The other pages are ways of stressing one part of it.

02 · Tools and MCP

How an agent touches the world, and how one API can front many models.

03 · Prompting and skills

What belongs in a prompt, what belongs in a skill, and two creative stacks.

04 · Multi-agent

05 · Runtime and infra

06 · Evals

A primer on outcome, trajectory, and cost. The survey reading of SWE-bench Verified is on harness engineering.

07 · Security

08 · Case studies

One distillation for each cluster of posts.

09 · Playbooks

Hands-on recipes. Start with your first agent if the sections above are still vocabulary.

10 · Hosted agents

Closed products, read from official pages: Grok Bot, Muse, Dots, Claude Cowork, and computer use in Copilot Studio. Each one is placed on the six harness parts.
