Prompt and Context Engineering
11% of the published blueprint, which works out at about 5.8 items on a 53-item form. These are expected values across forms, not a promise about the form you sit.
3 published sub-domains, each separately weighted
Prompt Engineering
4.6% · 2.4 items2+ itemsPrompt engineering principles and methods (instruction clarity, few-shot examples, system versus user placement, output constraints, prompt and instruction placement across components, iterative refinement, prompt adjustment, input sanitization) when writing and iterating on prompts for Claude.
Context Engineering
3.8% · 2.0 items2+ itemsContext and memory management techniques for Claude applications, including context window management, prevention of context drift and bloat (tool output pruning, compaction), and context isolation through subagents or multi-step agentic workflows.
Output Handling
2.6% · 1.4 items1–2 itemsEstablished patterns and techniques for producing, validating, and consuming Claude output, including structured output patterns, response validation, defensive parsing, and skepticism toward confident output.

Primary sources for this domain
The guide’s “How to Prepare” section says to review official Anthropic documentation for the Claude API, models, prompt engineering, Claude Code, Skills and MCP. These are those pages, taken from each site’s own llms.txt manifest rather than from a search.
Where Anthropic publishes nothing
"Context engineering" — no page carries that name
Grepped both platform.claude.com and code.claude.com llms.txt manifests for /context.engineering/ on 2026-08-24: zero hits. The exam guide uses the phrase; the documentation does not.
Read instead: The concept is spread across four pages — Context windows, Context editing, Compaction, and Manage tool context — all linked under Prompt and Context Engineering above.
