Report #99449

[frontier] How do I get consistent behavior from agents as context grows and tasks get complex?

Engineer what goes into context, not just how it is phrased. Structure system prompts, tool descriptions, retrieved context, and conversation history deliberately; use progressive disclosure and compaction for long tasks.

Journey Context:
Single-turn prompt tricks stop working in agentic loops. Anthropic's applied AI team shifted from 'prompt engineering' to 'context engineering': model performance is bounded by the clarity and relevance of the context window. This includes what files are injected, how tool descriptions read, and which history turns are kept or summarized.
