Prompting got you in the door. Context is what keeps the model right for the next
10,000 tokens — and the next 10,000 sessions. This is the world where you stop writing clever
sentences and start architecting what the model actually sees.

🎯 WHY THIS IS A FLAGSHIP WORLD
Every model release since 2025 has made one thing obvious: the model is rarely the bottleneck
anymore. Context is. A 1M-token window doesn't mean
better answers — it means more rope to hang yourself with if you don't curate what the model
actually sees. Andrej Karpathy called context engineering "the essential AI skill of 2026."
Anthropic's own engineering team frames it as a resource-allocation problem: context is finite,
with diminishing returns, and your job is finding the smallest set of high-signal tokens that
maximizes the model's odds of getting it right.
Prompt
Engineering (2025)
How you phrase one request,
inside one chat, one time.
Context
Engineering (2026+)
What the model carries across
an entire session, a whole codebase, and every session after this one.
🗺️ THE 10-MISSION ARC
Each mission is a layer. You build upward — from "why prompts fail" to a full context
architecture you could ship inside a real agent.

Context Engineering — Live Missions
Ten missions, progressive complexity. Each one teaches a real failure mode, a real
fix, and ships at least one copy-ready artifact — a system instruction, a CLAUDE.md, an AGENTS.md, a
compaction prompt — that you can drop into your own stack today.
