Recent highlights

This week was all about agent tooling: Claude Code shipped background agents and a native PR review flow inside the terminal, while the MCP protocol v1.2 added resource streaming and granular authorization. Together they make production agents noticeably safer and easier to run.

On the research side, the strongest signal is that structured retrieval consistently beats “long context” on real-world tasks — reinforcing the move toward economical architecture, with prompt caching cutting real API bills by 70%+. Alongside, the practical guides keep coming: from building your own code-review agent to an honest take on when fine-tuning actually pays off.

Analyzing Claude Code Token Overhead and Caching Costs Against OpenCode

A systematic analysis of developer agents reveals that Claude Code injects around 33,000 tokens of system prompts, tool schemas, and reminders before reading your query, compared to OpenCode's minimal 7,000 tokens. This overhead escalates with system instructions, custom AGENTS.md files, and active Model Context Protocol servers, heavily impacting prompt-caching efficiency.

How to Optimize Claude Session Limits and Avoid Context Bloat

A widely circulated habit of keeping a single massive chat thread to maintain context actually backfires by exhausting Claude's session limits. Because Anthropic calculates limits based on total tokens processed per turn, starting clean sessions and utilizing Claude Projects is far more efficient.
