CWA, Context Window Architecture

After thinking and response, let agent to choose to keep think procedure into the context or not.
The real value of an AI application isn't just the LLM, but the system intelligently managing its context.

Context Engineering Realized: Context Window Architecture
After working on this for some months now I would like to put it out there based on the considerable attention being put towards “context engineering”. I am proposing the Context Window Architecture (CWA) – a conceptual reference architecture to bring engineering discipline to LLM prompt construction. Would love for others to participate and provide feedback. A reference implementation where CWA is used in a real-world/pragmatic scenario could be great to tease out more regarding context engineering and if CWA is useful. Additionally I am no expert by far so feedback and collaboration would be awesome.

I recorded the requests Codex generated for a 16-character prompt and measured what changed as it loaded instructions, exposed tools, read files, ran commands, received images, and compacted its history
