本文研究Claude Code的上下文管理，核心是Prompt Cache作为设计底座。文章提出三条铁律：前缀匹配、字节变化即失效、断点决定缓存起点。由此衍生四大策略（压缩、结构化笔记、子代理分解、按需检索）和31条具体机制，所有设计均以维持缓存稳定为目标。文章还列出8处官方文档与源码不符之处，并预告后续7篇系列文章。

Sudeep Das shares how DoorDash shifts from legacy one-shot predictions to an agentic recommendation platform. He discusses leveraging language-native consumer memory, RQ-VAE semantic IDs for...

Baruch Sadogursky and Patrick Debois discuss why coding agents fail due to bloated context windows and stuffed prompts. They explain practical context engineering fixes, including lazy-loaded...

Now generally available, Pinecone Nexus is a "knowledge engine" for AI agents that transforms enterprise data into a structured layer agents can query directly. It enables teams to ingest and...

AI makes the first 80% of development feel fast, but hides architectural complexity until it's too late. To prevent system instability, engineering leaders must shift from raw throughput to...

The Model Context Protocol team has promoted its Enterprise-Managed Authorisation extension to stable status, adding a centralised way for organisations to control access to MCP servers through...

Adi Polak discusses the architecture required to transition from stateless prompts to state-aware, context-rich AI agents. Drawing on 15 years in distributed systems, she shares how engineering...

Michael Stiefel spoke to Baruch Sadogursky about software architecture in the age of agentic AI. LLM can function, albeit stochastically, as reasoning machines capable of interpreting human...

Airbnb has redesigned its identity system to support privacy-first social features in Experiences. The platform introduces context-specific profiles that separate global user identity from...

Go 语言中的 `context` 包用于管理请求的超时和取消信号，以防止 goroutine 泄漏。出现 "context deadline exceeded" 错误通常是因为请求未在设定的超时时间内完成。为避免此错误，应合理设置超时时间，使用 `context.WithTimeout`，监控请求，优化代码逻辑，并记录和分析错误，以提高系统的可靠性和用户体验。
