Claude Fable 5.2 Mastery Guide

Claude Fable 5.2 costs twice as much per token as Opus 5.5, yet on two of Anthropic's own tests it matched or beat Opus for half the cost per task or less. This free guide shows where Fable earns its price and how to brief it so it finishes the job: the F.A.B.L.E. brief, the routing rule against Opus 5.5, real costs with fast mode, the plan you need, and why it thinks long or stops early. You also get ten briefs built around what changed in 5.2, five project playbooks and a five-lesson course.

Context Engineering Mastery Guide

The model already has the skill. What it lacks is what only you know. This free guide teaches context engineering in nine short modules: the seven layers of a strong brief, six rules for high-signal context, patterns you can paste today, context for agents, and how to store your context once so every chat starts informed. It includes a ten-minute interview prompt that writes your AI context profile, plus ten templates to copy.

Harness Engineering Mastery Guide

When a coding agent fails, the model is rarely the cause. What surrounds it is. This guide teaches the harness in ten short modules: an instruction file the agent reads, memory that outlives the session, one feature at a time, verification it cannot argue with, and loops that prompt it for you. Comes with 12 template files to paste into any repo. Works with Claude Code, Codex and any agent that reads a repository. Free.
