What is the difference between context engineering and prompt engineering?

Prompt engineering focuses on crafting individual queries to get good responses. Context engineering is a systematic discipline that designs the entire information environment surrounding your AI interactions—including instructions, background context, task definitions, output formats, and variable injection points. Think of prompt engineering as writing a good question, while context engineering designs the entire conversation architecture.

How do I handle context window limits when my context block is large?

Use the tiered context strategy: place essential instructions and output format in the Priority 1 layer (always included), domain knowledge and examples in Priority 2 (included when space permits), and nice-to-have references in Priority 3 (trimmed first). Monitor your token usage and compress verbose sections using structured formats like tables instead of prose.

Can I reuse context blocks across different AI platforms?

Yes, well-engineered context blocks are largely platform-portable. The ICTO framework produces context that works across Claude, ChatGPT, Gemini, and Copilot with minor adjustments. Platform-specific parameters (like Claude's XML tag preferences or GPT's system message format) should be isolated in a thin adaptation layer rather than woven throughout your context block.

How do I measure whether my context engineering is actually effective?

Use the Context Effectiveness Scorecard: measure Output Consistency (same input produces same quality across 10 runs), Task Completion Rate (percentage of outputs requiring zero human editing), Edge Case Handling (how gracefully the AI handles unexpected inputs), and Token Efficiency (output quality relative to context size). A/B test context variations and track these metrics over at least 20 interactions per variant.
