Frequently Asked Questions

(01)Is Prompt Engineering dead?
No, but it's been absorbed into Context Engineering. Writing good prompts is still important – it's just one component of a larger discipline that includes memory management, tool integration, trust boundaries, and retrieval.
(02)What is the RGST model?
RGST stands for Role, Goal, State, Trust – the four pillars of Context Engineering. Role defines who the model is, Goal specifies the outcome, State provides current memory and facts, and Trust establishes boundaries for what the model can and cannot do.
(03)What is Context Rot?
Context Rot is the gradual degradation of model quality as more (often irrelevant) information is added to the context. The solution is the Write-Select-Compress-Isolate loop: continuously curate what enters context, not just append.
