Report #74842

[architecture] Agent relies entirely on infinite context windows instead of designing a memory architecture

Adopt a memory-first design: assume the context window is strictly bounded and design the agent's control flow around explicit read/write operations to external memory systems \(short-term, long-term, semantic\) before relying on in-context history.

Journey Context:
With the introduction of large context windows, developers are tempted to just stuff everything into the prompt. This is an anti-pattern because attention mechanisms degrade in the middle of long contexts \('lost in the middle' phenomenon\), retrieval latency increases, and inference costs scale poorly with context length. Memory-first design forces the agent to be deliberate about what it needs to know for the current step. The tradeoff is the engineering effort to build the memory pipeline versus the prompt-stuffing shortcut, but memory-first is the only pattern that scales reliably in cost and accuracy.
