Agentic Craft The Practical Guide to Prompts, Models, Tools, and AI Coding

Turn a prompt into proof.

AI can produce an impressive answer in seconds. Getting dependable work from it takes a different skill: choosing the right tools, defining the task, and checking what actually happened.

Agentic Craft teaches that skill through 24 practical chapters. Move from everyday ChatGPT and Claude workflows to coding agents, reusable skills, plugins, MCP connections, APIs, and multi-agent systems. Learn how to choose a model, calibrate reasoning effort, provide useful context, and give an agent enough authority to finish the job responsibly.

• Clear distinctions between models, product modes, reasoning effort, tools, and agent runtimes.


• Worked prompts and workflows for research, documents, coding, and automation.


• API examples that explain structured output, tool calls, validation, and recovery.


• Visual maps of context, connections, delegation, and verification.


• Practice labs with answer rubrics, reusable templates, and a capstone project.


• A directory of 91 official OpenAI and Anthropic sources, checked October 11, 2026.

The goal is practical judgment: know which control to change, what evidence to request, and how to tell whether a task is finished.
