Bringing Code Review to Claude Code
- Claude Code now has a built-in code review workflow — ask Claude to review your changes the same way you'd request a teammate review
- This moves Claude Code from 'write code for me' toward 'be my full development partner', covering the review step that was previously manual
- Official Anthropic blog post — code review is one of the most common developer workflows, and having it native to Claude Code removes the context-switch to a separate reviewer
- Pairs naturally with the Claude Code GitHub Action v1.0 (released last week) for automated PR review pipelines

Why the 1M context window burns through limits faster and what to do about it
- Every message you send re-sends your *entire* conversation to the API — message 50 includes all 49 prior turns before Claude starts on your new one. Without caching, a 100-turn Opus session would cost $50-100 in input tokens alone
- Anthropic caches aggressively (90% off for cache hits). One measured session hit 96.39% cache hit rate: 47M tokens sent, only 1.6M needed real compute
- The real cost driver is cache *busts* caused by the 5-minute TTL. A 6-minute coffee break on a 500K-token conversation costs ~$3.13 just in cache-write fees (billed at 125% of normal input rate)
- Common accidental cache busters: timestamps or dynamic content in your system prompt, switching models mid-session, adding/removing MCP tools (tool definitions are part of the cached prefix)
- Fix: keep system prompts fully static, don't swap models mid-session, batch MCP tool changes to the start, avoid pauses longer than 5 minutes when your context is large

MEX: structured context scaffold for Claude Code with drift detection
- MEX replaces one monolithic context file with a routing table in `.mex/` — Claude loads only the context relevant to the current task (working on auth? loads `context/architecture.md`, writing new code? loads `context/conventions.md`)
- A CLI runs 8 zero-token, zero-AI drift checkers: finds referenced file paths that no longer exist, npm scripts your docs mention that were deleted, dependency version conflicts, scaffold files not updated in 50+ commits
- When drift is found, `mex sync` builds a targeted repair prompt and fires Claude Code on only the broken files
